Cyanide Chemistry International Cyanide Management

The salts of sodium, potassium and calcium cyanide are quite toxic, as they are highly soluble in water, and thus readily dissolve to form free cyanide. Operations typically receive cyanide as solid or dissolved NaCN or CaCN 2. Weak or moderately stable complexes such as those of cadmium, copper and zinc are classified as weakacid dissociable WAD. Although metalcyanide

Extraction of gold using cyanide NZQA

Extraction of gold using cyanide Gold is found in very low concentrations in the ore from which it is mined. To collect the gold from the ore it needs to be separated from the other minerals in the ore. To do this the gold needs to be made into a soluble form so that it can be separated from the other minerals as gold is insoluble. To make gold soluble sodium cyanide

Extraction of Gold Element Gold, Au, Transition Metal

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
