Gold Recovery Study from a Small Scale Mine Tailings

Artisanal Gold Mining (AGM) in 2013 accounted for approximately 12 to 15% of all the gold produced in the world. In many countries, the main method of extraction is whole ore gold amalgamation using mercury in a grinding media. This technique loses to the environment 30 to 50% of the mercury added into the mill and only around 30% of the gold is extracted.
