| Abstract: | Aiming at the valuable elements in the cyanidation tailings of gold mine production, copper, lead, zinc, gold, silver and NaCN is comprehensively recovered by lead-zinc selective mixed flotation, sulfuric acid decyanation activation and copper-sulfur separation process. The lead grade in mixed concentrate is 25.00 % and its recovery rate is 65.60 %. The zinc grade in mixed concentrate is 27.00 % and its recovery rate is 70.90 %. The grade of copper concentrate is 15.25 % and its recovery rate is 75.48 %. Meanwhile, some by-product gold and silver is obtained. |
