How Is Gold Processed? | ReferenceGold is processed by cyanide milling, a chemical procedure that separates 95 to 98 percent of the gold from raw mined ore It is then refined to the gold standard purity, according to Mineweb Heap leaching is a less expensive method of gold extraction, but it is a longer process and it recovers less gold than the cyanide milling processPURE GOLD AND IRON FROM ...
This is an effective goldrefining process that requires the use of a chemical solution (flux) known as Aqua Regia. The purpose of this method is to dissolve any other metals that may attach to gold in its ores or alloys. This process can be done smallscale and it is practically affordable because a 500ml of Aqua Regia kit costs about
Apr 24, 2017· Another largescale gold refining technique, the Wohlwill Process refines gold to % purity — the highest purity possible. Developed by Emil Wohlwill in 1987, this electrochemical process uses a 95% pure gold bar as an anode and small sheets of pure, 24karat gold as the cathode.
