The use of mercury in gold mining is causing a global health and environmental crisis. Mercury, a liquid metal, is used in artisanal and smallscale gold mining to extract gold from rock and sediment. Unfortunately, mercury is a toxic substance that wreaks havoc on miners' health, not to mention the health of the planet.
There has been much interest in copper in the last 10 years, in Chile. More recently, small copper mining companies have found success in small scale leaching/ SX/EW copper operations in Chile. Most major (US/Canadian/British) companies in Chile require huge massive copper deposits to justify the Billion USD required to open a large copper mine.
