The technique of amalgamation, alloying with mercury to improve the recovery of gold, was discovered at about this time. The colonization of South and Central America that began during the 16th century resulted in the mining and refining of gold in the New World before its transferal to Europe; however, the American mines were a greater source of silver than gold.Get Price
In production practice, the commonly used process for beneficiation ofgold-bearing sulfide ore is: flotation first, and the flotation concentrate can be directly cyanidized or re-grinded and then cyanidized, or treated with gravity separation andamalgamation.

nature. Where amalgamation plants could recover about 60% of the gold present, cyanide could recover about 90%. Because of the improved recovery, many of the old tailings piles from other processes have been economically reprocessed by cyanide leaching. Cyanide is as close to a “universal solvent” for gold as has been developed.Get Price
