| The features and problems of refractory As-C bearing gold ore reserves,as well as the situation of treatment technology are discussed in this paper.Based on the present research projects,the major breakthrough in the field of gold extraction processes,such as strengthened mineral processing and metallurgical technology new technology of no- cnanide extraction, new extraction technology of mineral processing- roasting- cyanide leaching,and mineral processing- thermopressure oxidation-cyanide leaching,is of great sig- nificance to the treatment of refractory gold ore. |
