Gold Extraction & Recovery Processes

29/02/2016· Gold Recovery Gold recovery comprises similar stages to the processing of most ores First, the valuable minerals are separated from the gangue through concentration The final concentrate is obtained by repeated processing and is smelted or leached in order to get a Dore bar In generals, the concentration of gold includes three stagesThe extraction of gold by the cyanidemethod is of great technical importance It is effected by lixiviation with a solution of potassium cyanide, the gold being precipitated either by addition of zinc or electrolytically The process was suggested by Mac Arthur and Forrest in 1385, and is based on the wellknown solubility of gold in potassiumcyanide solution, a phenomenon said to have beenExtraction of Gold
