    Impacts Of Artisanal Mining On Some Heavy Metals

    The other heavy metals quickly decompose into compounds that are then dissolved away as they are exposed to weathering. The most common impurities in native gold are trace amounts of silver, copper, zinc, and lead. Native gold is gold as it is found, before any refining. Gold is often found as a by product of the mining of these other heavy metals.Placer gold mining, which extracts gold from buried or exposed alluvia, is often conducted on or near streams. Such mining has the potential to adversely affect water quality. Other heavy metals associated with the gold (such as arsenic, cadmium, lead, zinc, and copper) may be freed to enter streams.
