The 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 been ...

Extraction of metals and the reactivity series. The most reactive metals are at the top of the series; The tendency to become oxidised is thus linked to how reactive a metal is and therefore its position on the reactivity series; Metals higher up are therefore less resistant to oxidation than the metals placed lower down which are more resistant to oxidation

Gold Cyanide Solution (Leaching Gold With Cyanide) ... Another element that plays with the cyanide chemistry is nickel. Nickel, however does not interfere with the gold going into solution, but rather the precipitation of the gold from the cyanide solution. Arsenic and antimony do present a larger problem, by reacting with the cyanide and using up all of the excess oxygen, leaving little or no ...
