Reducing disease and death from Artisanal and Small-Scale Mining …

Abstract. Artisanal and small-scale mining (ASM) takes place under extreme conditions with a lack of occupational health and safety. As the demand for metals is increasing due in part to their extensive use in 'green technologies' for climate change mitigation, the negative environmental and occupational consequences of mining practices are disproportionately felt in low- and …

A Review of the Scope of Artisanal and Small‐Scale Mining Worldwide

Abstract. Some of the poorest people in the world's poorest countries eke out a living in artisanal and small‐scale mining (ASM). Equipped with primitive tools like picks, shovels, buckets, and gold pans, they work mining valuable resources, like gold, diamonds, tin, lithium, rare earth elements, tantalum, and cobalt, and any other usable commodity, for example, sand, coal, or mica.
