Abstract：
 The present invention relates to metallurgical technology and technological process and features that gold is extracted from cyanide gold refining waste slag as material by means of catalytic oxidation process to leach gold wrapping mineral and the subsequent common cyanide gold refining process. The technological process is simple and can reach a gold extracting rate as high as 90 %. The present invention can reduce the harm of cyanide gold reinfing waste slag to environment while obtaining gold.
