  • Optimization Of Cyanidation Parameters To Increase The

    although gold cyanidation plant practice in aghdarre has improved significantly in recent years, process optimization is still under development. cyanide has been the universal reagent for gold leaching on counts of higher stability, lower cost and better understood chemistry. the miller process uses gaseous chlorine to extract impurities when gold is at melting point; impurities separate into a layer on the surface of the molten purified gold. the miller process is rapid and simple, but it produces gold of only about 99.5 percent purity. the wohlwill process increases purity to about 99.99 percent by electrolysis.the plant cyanide addition rate. cyanide control in the metallurgical process of gold extraction in anglogold by b.j. vorster and s.r. flatman synopsis anglogold south africa region currently consists of twelve gold plants. these plants use a combined total of $20 million of cyanide per annum.
