HOTAZEL, South Africa — Dirk Jooste had by no means been a giant drinker. However when he confirmed up for his job as an electrician at a manganese mine within the Kalahari Desert one Monday morning, he was trembling a lot that his supervisor requested him if he was “babalas,” or hung over.
Jooste, then in his early 50s, quickly misplaced the power to maintain his steadiness, stroll straight and bear in mind issues as primary because the TV present he’d seen the evening earlier than, he recounted greater than a decade later. Finally, a health care provider delivered information that shocked Jooste: The powdery black manganese mud he’d labored with every day for years appeared to have prompted irreversible poisoning.
As demand for electrical autos has soared in recent times, automakers have quickly turned to manganese, a standard and comparatively cheap mineral that’s already utilized in about half of rechargeable batteries and is seen as key to creating provide chains extra dependable and vehicles extra inexpensive. The business’s demand for manganese has quintupled over the previous 5 years, and analysts predict it may improve an extra ninefold by 2030.
For years, nonetheless, manganese has taken a toll on the well being of those that mine and course of it, in accordance with scientific analysis that reveals that high-level publicity might be poisonous, inflicting a spectrum of neurological hurt. In South Africa, dwelling to the world’s largest manganese reserves, interviews with dozens of present and former workers in mines and smelters, in addition to with medical doctors and researchers, underscore the peril.
Amid the brand new world fervor for manganese, nonetheless, the business has proven little consideration of those occupational dangers, in accordance with analysts who concentrate on the vitality transition.
The shift to EVs already figures prominently within the world battle towards local weather change, and that transition is stoking demand for a variety of minerals utilized in manufacturing them, comparable to manganese, cobalt, lithium and nickel. To run, EVs sometimes require six occasions the mineral enter of standard autos, as measured by weight, excluding metal and aluminum. However there stays little recognition of the hurt that the extraction and processing of such minerals may have on employees and surrounding communities.
Dirk Jooste, 65, labored as an electrician blowing manganese mud out of damaged truck air conditioners on the Mamatwan mine close to Hotazel in South Africa’s Northern Cape.
“How lengthy is it going to take till folks begin realizing what is going on? One other 30 or 40 years? Should we wait till folks begin dying?”Dirk Jooste
Dirk Jooste, 65, labored as an electrician blowing manganese mud out of damaged truck air conditioners on the Mamatwan mine close to Hotazel in South Africa’s Northern Cape.
Present and retired manganese miners within the distant Kalahari Desert mentioned their recollections have declined after years of working within the mines, whereas former smelter employees discovered themselves unable to stroll a straight line. One latest research discovered that 26 % of manganese miners studied in Hotazel, the Northern Cape mining city the place Jooste labored, exhibited signs much like these of Parkinson’s illness. Many present and former miners mentioned they have been by no means warned concerning the potential risks of publicity. Former miners and smelter employees who raised issues mentioned they have been ignored.
Clear vehicles, hidden toll
A sequence unearthing the unintended penalties of securing the metals wanted to construct and energy electrical autos
Analysts who carefully comply with the EV business be aware that there was little dialogue amongst automakers and their suppliers concerning the potential well being hazards, including that the businesses are largely involved about whether or not there’s sufficient high-purity manganese — which is particularly required for EV batteries — to satisfy demand. Tesla, Ford and Chevrolet, which bought the most-popular EVs in america final 12 months, didn’t reply to requests for remark.
Aloys d’Harambure, govt director of the Worldwide Manganese Institute, which represents the manganese business, agreed that extra publicity to the mineral can result in irreversible neurological harm that’s related to the illness generally known as manganism. However, he added, “due to present applied sciences and labor laws, in addition to measures on security issues, manganism is never seen at the moment.” He mentioned using manganese in EV batteries remains to be such a small a part of the general market — the overwhelming majority of manganese goes towards metal — that “now we have not but seen any elevated dialogue or extra analysis on the subject of potential well being impacts of high-purity manganese.”
Manganese mining infrastructure in Hotazel.
The problem is very pressing in South Africa, which has seen its manufacturing of manganese improve by greater than one-third since 2017 and, because the world’s largest producer, now accounts for about 36 % of the worldwide whole, adopted by Gabon and Australia.
South32 and Assmang, two main manganese mining corporations in South Africa, mentioned their risk-mitigation methods are knowledgeable by analysis on the potential well being results of publicity to manganese mud.
Docs and medical researchers agree that defending human well being will take higher recognition of the menace and extra vigilance than prior to now, together with rigorous monitoring, protecting gear and proactive medical surveillance applications.
Jooste, for one, has little confidence. Sitting in his physician’s workplace, Jooste, now 65, mentioned he fears that South Africa is repeating its ugly historical past with asbestos mining, which continued for years after the well being dangers to employees and close by communities have been identified.
“How lengthy is it going to take till folks begin realizing what is going on?” Jooste mentioned of manganese, his voice rising in irritation. “One other 30 or 40 years? Should we wait till folks begin dying?”
Within the huge panorama of the Kalahari Basin, manganese mining operations have expanded as demand for the ore grows. An extended historical past and a ‘new frontier’
Way back to 1837, a Scottish doctor, John Couper, detailed the struggling of employees uncovered to manganese at a bleach manufacturing unit outdoors Glasgow. He reported males staggering after dropping energy of their legs and struggling to talk clearly, their face muscular tissues paralyzed.
As extra research have been finished on the situation that grew to become generally known as manganism, researchers recorded different signs, together with tremors and emotional instability, typically termed “manganese insanity.” They decided that manganese poisoning happens when the substance is inhaled or ingested, will get into the bloodstream and is deposited within the basal ganglia, the a part of the mind that controls motion and steadiness.
Because of enhancements in office situations in latest many years, full-blown manganism is now uncommon, researchers say. What’s extra frequent, they are saying, are refined signs together with slowness of motion, stiffness in joints, irritability and forgetfulness, all of which might be tough to diagnose. Tomás R. Guilarte, a professor of environmental well being sciences at Florida Worldwide College, mentioned that though the hyperlinks between excessive manganese publicity and toxicity are clear, the genetics that make some folks extra weak nonetheless should be studied.

Brad Racette, chair of neurology on the Barrow Neurological Institute in Arizona, has studied the well being outcomes of manganese miners in Hotazel.
In Hotazel, a city surrounded by big mines crammed with darkish grey manganese ore, neurologist Brad Racette examined 187 manganese miners, whose common age was 42. Racette, chair of neurology on the Barrow Neurological Institute in Arizona, discovered {that a} quarter of those miners skilled Parkinsonian signs, comparable to abnormally stiff and gradual motion. His workforce, which carried out the research between 2010 and 2014, additionally discovered that these signs have been related to a decrease high quality of life, as reported by the employees in surveys.
“We’re nonetheless peeling the layers off this onion,” Racette mentioned. “My query at this level is how low the [exposure] ranges must go earlier than they’re protected.”

Research of employees at an Italian plant producing manganese alloys for steelmaking within the late Nineties additionally discovered that they exhibited uncommon slowness of motion and lack of steadiness, mentioned Roberto Lucchini, a professor of occupational and environmental well being at Florida Worldwide College. Lucchini, who remains to be finding out these employees, mentioned that through the years they’ve developed comparatively excessive ranges of a kind of plaque buildup within the mind that’s usually an indicator for Alzheimer’s illness.
He and different researchers mentioned authorized publicity ranges stay far too excessive in a lot of the world, together with South Africa. Research in Italy, Taiwan, Bangladesh and Ohio have highlighted the potential hazard even of exposures beneath the authorized limits.
As a result of EV batteries require high-purity manganese, Lucchini mentioned, there’s prone to be an excellent higher menace in refineries than in mines, the place the mud is coarser and thus much less prone to attain the mind straight.
“This,” Lucchini mentioned, “is a brand new frontier.”
Manganese mining operations within the Hotazel space. Issue dealing with a cup of espresso
After 10-hour workdays on the huge open-pit mine, Jooste mentioned, he would return to his home and discover his nostril, enamel and even tongue lined in positive black mud. “It was all black,” mentioned Jooste, who labored as a contractor blowing the mud out of damaged truck air conditioners on the Mamatwan mine. “The whole lot.”
After that long-ago day when his supervisor requested if he had a hangover, Jooste headed to the clinic on the mine, which was then owned by the Australian mining big BHP Billiton and later spun off with different operations underneath the company identify South32. He mentioned the physician identified him with Parkinson’s illness.
However Jooste, a tall man with a shock of grey hair, seen that a few of his signs weren’t similar to these related to Parkinson’s. When one other physician prescribed treatment for Parkinson’s, it didn’t work.
Finally, Jooste landed within the workplace of Tidu van der Merwe, an occupational well being physician within the close by mining city of Kathu. Earlier in his profession, van der Merwe had presciently warned about hazardous situations at a manganese smelting plant, the place a spate of suspected manganism circumstances have been later reported. He knew that Jooste’s job on the mine had entailed excessive publicity — he’d worn solely a skinny masks — and acknowledged that his signs mirrored many within the medical literature. He identified Jooste with manganism.
Greater than a decade later, Jooste’s hand-eye coordination has grow to be so dangerous that he has hassle handing his spouse a cup of espresso with out spilling it. “That is no life,” mentioned Jooste, whose case was first reported final 12 months by Carte Blanche, an investigative outlet in South Africa.
A spokesman for South32 declined to touch upon particular person circumstances however mentioned in an announcement that the corporate takes “proactive steps to scale back the danger by making use of controls in step with worldwide finest apply,” together with using protecting tools for sure work teams, dust-suppression methods, and air flow in underground mines. The spokesman mentioned that if employees show “any signs of occupational sickness, we take it very severely,” and that after screening, they’d be despatched for medical analysis.
Tidu van der Merwe, proper, an occupational well being physician within the mining city of Kathu, identified Jooste with manganism after a earlier physician mistook his signs for Parkinson’s illness.
Whereas science is evident concerning the potential peril posed by manganese, the extent of the hurt being finished to employees in South Africa stays much less sure, partially as a result of there’s so little monitoring and so little analysis. Jaco Cilliers, a neurologist in Bloemfontein, mentioned that screening for manganese poisoning is uncommon and that when he meets together with his medical colleagues, it’s “not one thing that will get talked about.”
Ewert Bohnen, a health care provider whose agency is on contract with the businesses to run well being clinics at 5 manganese mines within the Northern Cape, mentioned he’s had no suspected manganese poisoning circumstances over 15 years. Nearly all of circumstances he’s heard about, he mentioned, come from smelters, which primarily course of manganese for steelmaking.
In cities close to the mines, many different medical doctors declined to speak to reporters about manganese. A physician at Assmang Black Rock mine hung up when a reporter mentioned why she was calling. 4 occupational well being medical doctors in Kuruman, who, in accordance with their receptionist, handled “heaps” of manganese miners, declined to remark. A physician in Hotazel mentioned in a quick cellphone interview that he’d had one manganism affected person, who died, however the physician declined to satisfy, saying questions ought to be directed to the mines.
Jonathan Myers, previously a professor of occupational well being on the College of Cape City, mentioned he carried out a research within the Northern Cape 20 years in the past that discovered no adversarial neurological results of manganese publicity in additional than 400 lively miners.
Van der Merwe mentioned he worries that circumstances could also be going unnoticed due to variations in language and tradition, particularly between administration and medical workers on one hand and Black miners, who’ve traditionally been the spine of South Africa’s mining business, on the opposite.
“I’m sticking my neck out speaking about this,” he mentioned, including that worry of the mining corporations is widespread.
Boipelo Sekwe, second from left, a miner who lives in Hotazel, celebrates her forty eighth birthday with mine colleagues. ‘We overlook stuff’
In two villages close to the mines, dozens of former miners, all Black and a few sporting their outdated mining uniforms, recounted their well being illnesses to visiting reporters at casual group heart conferences. A number of the former miners cited the identical refined signs that researchers have recognized, and plenty of mentioned that they had sought medical assist however run into useless ends. They instructed of medical doctors who mentioned the illnesses may very well be associated to manganese however who declined to supply official diagnoses.
“There isn’t any readability,” mentioned Looseboy Picoentsi, 62, in Ga-Mopedi village, who added that his physician instructed him his sharp decline in reminiscence may very well be associated to manganese. However when Picoentsi tried to get his well being data from the mine the place he’d labored, he was instructed they didn’t have them anymore.
Lekgetho Mosimaneotsile, 64, additionally of Ga-Mopedi, had labored at Assmang’s manganese mine for 27 years, a lot of them spent blowing manganese mud out of storerooms. He mentioned he began experiencing chest pains and forgetting issues whereas he was nonetheless working within the mine. Now, he mentioned, his reminiscence is so dangerous that when he leaves his home to get one thing, he’ll overlook what it was. Generally when he wakes up within the morning, he can’t cease his physique from trembling.

A spokeswoman for Assmang mentioned it conducts a medical surveillance program and warns workers concerning the potential risks of manganese publicity. The spokeswoman, who spoke on the situation of anonymity, citing firm coverage, mentioned there have been no circumstances of manganese poisoning at Assmang’s mines.
In one of many Hotazel neighborhoods the place present miners reside in housing backed by the businesses, a number of complained of reminiscence loss and different illnesses. Elias Gasejewe, 53, who has labored in an underground manganese mine since 2005, mentioned he’s been forgetting issues for years and looks like his thoughts works extra slowly than it as soon as did. Though the mining firm encourages employees to put on masks, he mentioned, he nonetheless sees the black mud blended in his mucus.

Saichile Mashele, 28, shatters sheets of manganese steel.Shards of manganese steel are washed. The shards will then be crushed and ultimately shipped to MMC’s clients.
Ernest Hendrik, 53, has labored in the identical underground mine, and in addition mentioned he suffers from reminiscence loss, in addition to joint stiffness and problem with coordination. He mentioned he is aware of many miners who’ve fallen ailing, however usually after they retire.
When Boipelo Sekwe, a present miner, was approached by reporters and requested whether or not she had any well being issues, she was in the course of celebrating her forty eighth birthday. She paused from dancing to Afrobeats music and consuming beer and responded: “We overlook stuff. A hundred percent of us overlook stuff.”
The Samancor smelter in Meyerton, outdoors Johannesburg, the place dozens of employees within the early 2000s raised complaints about manganese. A combat for compensation
Ezekiel Makhanja’s questions began within the early 2000s when he seen his co-workers at a manganese smelting plant in Meyerton, outdoors Johannesburg, falling sick. Makhanja, who labored within the smelter’s lab, visited the medical clinic and requested the nurses: “What’s happening right here?”
That query could be on the coronary heart of a years-long effort by employees at two smelters to get the mining giants that owned them to acknowledge the peril posed by manganese.
On the Samancor plant the place Makhanja labored, then owned by BHP Billiton and now by South32, 5 employees who medical doctors mentioned had developed manganism in the end acquired settlements from BHP Billiton. These employees have been all White, held supervisory positions and exhibited “extreme and excessive” signs, mentioned Richard Spoor, a lawyer who represented them. The businesses didn’t reply to requests for remark concerning the settlements.
Makhanja and lots of of his co-workers, largely Black workers who have been laid off within the early 2000s, acquired nothing. Spoor mentioned his makes an attempt to get settlements for a lot of of these employees have been stymied as a result of medical doctors offered them official diagnoses solely in the obvious circumstances.
Looseboy Picoentsi, 62, of Ga-Mopedi village, labored on the Mamatwan open-pit mine for years. His physician instructed him his sharp decline in reminiscence may very well be associated to manganese publicity.

Looseboy Picoentsi, 62, of Ga-Mopedi village, labored on the Mamatwan open-pit mine for years. His physician instructed him his sharp decline in reminiscence may very well be associated to manganese publicity.
Makhanja, now 59, is usually confined to his mattress today. Struggling to talk, he mentioned it’s been a very long time since he may stroll with out falling down. He sweats profusely at evening. He shakes and forgets issues. He mentioned it was after his buddies and associates — a few of them of their 30s and 40s — began dying that he realized the reply to the query he’d requested on the clinic: “That is poison.”
At a smelter outdoors Durban owned by the Assmang mining firm, Spoor helped 10 employees identified with manganese poisoning get funds from the federal government company chargeable for compensating folks injured on the job.
An inquiry by South Africa’s Labor Division into the Durban plant concluded that Assmang had created a hazardous working setting and had didn’t warn employees about potential risks, in accordance with a 2010 report by the division’s inspector. The company advisable, partially, that publicity limits be lowered to beneath the authorized threshold, which the inspector discovered was “not protected sufficient.”
The Assmang spokeswoman mentioned the corporate was not conscious of the inquiry’s conclusions and disputed the manganism diagnoses, whereas acknowledging that the employees had been completely disabled.
A view of the Manganese Metallic Co. plant.Threat is inevitable
The Manganese Metallic Co.’s refinery in Mbombela sits simply throughout from the famed Crocodile River main into Kruger Nationwide Park, the plant’s black equipment contrasting with the encompassing inexperienced hills. The corporate, which additionally produces materials for welding rods and ship propellers, amongst different merchandise, is one in all only some outdoors China making the high-purity manganese wanted for EV batteries. Right here, ore from the Kalahari just isn’t smelted however slightly dissolved in huge purple vats of sulfate answer, then electrified to provide a high-purity steel that may later be transformed after it leaves the plant into the sulfate type required by battery cathode precursor makers.
Throughout a tour organized for reporters, indicators reminding employees to put on masks and protecting ear coverings abounded. Staff had on lengthy sleeves and lengthy pants. Hannes Raath, the physician who has run MMC’s occupational well being clinic for the previous 22 years, mentioned employees put on displays to make sure that the quantity of mud is inside protected limits. In among the locations with the best concentrations of manganese mud, there have been few workers to be discovered.
Raath mentioned he has seen 5 to seven manganism circumstances throughout his time on the refinery, however none in recent times. He mentioned that’s as a result of the corporate has put a precedence on medical surveillance, together with neurological screenings and follow-up MRIs if wanted.
Ezekiel Makhanja, 59, labored within the lab of the Samancor smelter in Meyerton, testing manganese samples. Now he’s too sick to get away from bed most days, sweats profusely at evening and suffers from frequent shakes.

Chief govt Louis Nel mentioned the corporate has taken steps to scale back threat as a lot as attainable, together with implementing security procedures and offering employees with protecting gear. However he acknowledged that some threat is inevitable. Certainly, close to the furnaces the place manganese is dried, black mud particles coated a reporter’s cellphone display screen. However Nel mentioned the corporate has tried to “engineer out as a lot of the danger as we are able to.”
It stays unclear how severely the broader business is taking the hazard. Analysts at 4 analysis and consulting companies that comply with the EV and minerals sectors mentioned that threat to manganese employees is never a subject of dialogue amongst automakers, suppliers and buyers.
“The main target is on find out how to meet demand in a manner that’s cost-beneficial,” mentioned Victoria Hugill, a battery analysis analyst with Rho Movement. “The extra worker-focused questions and issues are decrease on the meals chain.”
Sam Jaffe, vice chairman of battery storage at E Supply, one other consulting and analysis agency, mentioned the neurological dangers posed by manganese have been “in no way” on his radar. He famous that it’s notably tough to evaluate the hazards of manufacturing high-purity manganese as a result of so lots of the refineries are in China. Likewise, d’Harambure, of the Worldwide Manganese Institute, famous that greater than 95 % of refined manganese is produced in China, the place “the entry to data on employee publicity, protecting measures taken by producers, and attainable environmental and group impacts is extraordinarily restricted.”

Trucker Tawanda Kembo arrives at a mine owned by South32 to gather uncooked manganese ore and ship it to a port on the South African coast.
Wei Zheng, a well being science professor at Purdue College in Indiana, has been finding out manganese manufacturing in China for many years. He recalled watching employees at a refinery in Guizhou province who have been producing high-purity manganese for a wide range of makes use of, together with rechargeable batteries, take away their protecting gear as they walked into the plant, selecting consolation over security.
Zheng, who visited the refinery in Guizhou a number of occasions, mentioned the business must reckon not simply with the well being issues of employees but additionally with the broader environmental impacts of increasing manganese mines and processing services.
“It’s about households, neighbors and communities,” Zheng mentioned. “It’s not simply concerning the employees. It’s about everybody surrounding the employees.”
