How to extract gold from its ore? The most common techniques in the United States use cyanide in various ways In one, the ground ore is put into a tank containing a weak cyanide solution and zinc is added The zinc causes a chemical reaction which separates the gold from the ore The gold is then removed from the solution with a filter pressThe GravityBorax Method GBM is still unknown to most Artisanal and smallscale gold miners (ASGMs) worldwide as most still use mercury to extract gold “Wholeore amalgamation” is a technique that requires the use of 10–25 g of mercury to produce 1 g of goldtechniques to extract gold from ore aircraftenginecz
