The Borax Method of Gold Extraction for SmallScale Miners

This method, along with many others, was eventually replaced by amalgamation, a process whereby mercury captures finegrained gold by forming an amalgam with the precious metal. The method is easy to learn and does not require expensive equipment. Today, more than ten million artisanal and smallscale gold miners (ASGM) Background.
