Borax Method of Gold Extraction. Unfortunately, this method is ineffective in areas using whole-ore amalgamation, since up to 90% of the mercury is lost to the tailings (the waste product consisting of fine sand) and only 10% is lost by blowtorching of amalgam. Thus, only a small fraction of the mercury spill from whole-ore amalgamation can be ...
