What are the chemical or physical separation methods used

Jun 15, 2020Steven Cochran's answer to What is the chemical method used to refine gold? Now, if you're searching for how it is first separated from the rock, this is a simple explanation: When gold ore is dug out, the rocks crushed int small pieces, then ground down into finer pieces. This is treated with a cyanide solution to pull the gold into solution. Get price
