Extraction of Gold

The extraction of gold by the cyanide-method 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 well-known solubility of gold in potassium

Gold Extraction Techniques Manhattan Gold & Silver

Apr 06, 2016 One of the earliest methods for extracting gold, salt cementation, was perfected through the Iron Age. When the Lydian Empire was standardizing the purity of the gold and silver they were using for the world’s earliest coinage, this was the method they relied on. When mined, gold is commonly merged with silver as an alloy called electrum.
