Abstract

Recent research work in hydrometallurgical processes for precious metals recovery from refractory ores is analyzed. Advantages and applications are discussed. Likewise, two methods, one stage direct pressure oxidation/cyanidation and pyrometallurgical recovery, are also described. In the first one, gold and silver oxidation and recovery can be carried out in the same reactor simultaneously. A higher than 96 % recovery in less than 90 min can be achieved. As for the pyrometallurgical recovery method, lead paste from automotive discharged batteries is use and no sulfur dioxide is generated. A precious metals recovery higher than 96 % is reached.
