摘要
某硫化物包裹型难处理金矿石Au品位为3.18g/t,44.18%的金被硫化物包裹,常规氰化浸出率低,仅为24.25%;通过采用浮选—细菌氧化—磁场强化氰化浸出工艺处理,金浸出率显著提高,金浮选、氰化综合回收率达82.55%。
The gold grade of a certain sulfide-inclusion type refractory gold ore is 3.18 g/t, and 44.18% gold is of sulfide-inclusion type. The traditional cyanidation leaching rate of gold is only 24.25%. With floatation-bacterial oxidation-magnetic field strengthening cyanidation leaching technique, the gold leaching rate is enhanced to 82.55%.
