Abstract

The present work summarizes the experiences oriented to develop a hydrometallurgical process that will not need any kind of cyanide. It also has to be applicable to metals recovery from printed circuit boards. Therefore, solutions of aqua regia, ammonium thiosulphate, sodium thiosulphate and thiourea, were employed. By UV/Vis spectrophotometry it was able setting up an analisys cuantitative technique for gold detection. Besides it is exposed the results gathered after the CIP (carbon-in-pulp) adsortion/desortion tests.
