Artisanal and smallscale gold mining operations have been conducted in Ghana for centuries. Over time technological advances in the industry occurred and miners separated from largescale mining and applied this knowledge to smallscale or individual mining practices
per cent of the global gold supply 80 per cent of the global sapphire supply and 20 per cent of . ASM relies on a mostly unskilled workforce using rudimentary tools and techniques. Unsurprisingly Artisanal and smallscale mining is also the
artisanal and smallscale gold mining due to its ease of use low cost and abundant supply. Whole ore amalgamation dramatically increases the potential for the mercury that is used to be released to the environment. In some cases this excess mercury approaches 90 of the total in use. Alternative techniques include many options for concentrating
