The demand for manganese, a crucial component in rechargeable batteries, is rapidly increasing due to the surge in electric vehicle (EV) production. However, the industry’s focus on supply chains and affordability overshadows the significant health risks associated with manganese mining and processing. Manganese miners, particularly in South Africa, are facing serious neurological disorders due to prolonged exposure to manganese dust. Despite these health risks, the industry has largely neglected these occupational hazards. High-purity manganese, specifically needed for EV batteries, is a primary concern among automakers and suppliers. Yet, there is little discussion around the potential health impacts, underscoring the need for greater attention and stricter safety regulations in the sector.

Bullet Points:

• Manganese, used in rechargeable batteries for EVs, has seen a quintupled demand in the past five years, a trend predicted to increase ninefold by 2030.
• Health risks associated with manganese mining and processing, including irreversible neurological harm, have largely been ignored amidst the rising demand.
• Workers in the manganese industry, especially in South Africa—the world’s largest producer—are facing serious health issues due to exposure to manganese dust.
• The EV industry has shown little consideration for these occupational risks, focusing more on securing a reliable supply of high-purity manganese required for EV batteries.
• Companies need to acknowledge the potential dangers and implement rigorous safety measures, proactive medical surveillance programs, and improved risk-mitigation strategies to protect workers.
• The situation is notably urgent in South Africa, which has increased its manganese production by over a third since 2017 and now accounts for about 36% of the global total.
• Major South African manganese mining companies, South32 and Assmang, claim to base their risk-mitigation strategies on the potential health effects of manganese dust exposure.
• Some fear a repeat of the historical negligence shown in asbestos mining, where health risks were known but overlooked for years.
