Abstract:
    The present invention is floating process for enriching Cu, Ag, Au, etc from gold sulfide ore cyanizing gold extraction tailing, and belongs to the field of metallurgical chemical technology. The floating process includes the following steps: 1. setting the tailing into a conditioning tank and regulating the ore slurry density to 40-60 % via stirring at normal temperature; 2. setting into an acidifying tank, regulating the acidity with sulfuric acid to pH 5; 3. adding water to regulate the ore slurry density to 20-30 % and pH to 6 in the conditioning tank while continuous feeding and discharging; 4. adding floating reagent and foamer in a floating tank via stirring; and 5. closed path floating in the floating tank to enrich Cu, Ag, Au, etc. The present invention has simple technological process, high metal recovering rate and other advantages.
