There are roughly forty-five million people around the world directly involved in ASM, which represents an astonishing 90 percent of the world’s total mining workforce. Despite the many advancements in machinery and techniques, the formal mining industry relies heavily on the hard labor of artisanal miners to boost production at minimal expense. The contributions from ASM are substantial, including 26 percent of the global supply of tantalum, 25 percent of tin and gold, 20 percent of diamonds, 80 percent of sapphires, and up to 30 percent of cobalt.
