摘要
针对毕力赫金矿矿石性质,考察了环保型浸金剂与氰化钠的浸出效果。结果表明:在相同工艺条件下,环保型浸金剂的浸金指标与氰化钠相当,且生产成本相差不大;磨矿细度-0.074 mm占90%,环保型浸金剂用量1.2 kg/t,浸出时间48 h时,金浸出率可达到92.59%。该环保型浸金剂浸出率高,生产成本低,可以替代氰化钠进行浸金作业,具有良好的应用前景。
According to the gold ore properties in Bilihe Gold Mine,the paper investigated the leaching effect of environmentally friendly agent and sodium cyanide.The results show that under the same process conditions,the leaching index and production cost of environmentally friendly agent and sodium cyanide are close;with grinding fineness of 90 %-0.074 mm,environmentally friendly agent dosage of 1.2 kg/t,leaching time of 48 h,the gold leaching rate can reach 92.59 %.The environmentally friendly leaching agent has high leaching rate and low production cost,making it an alternative to replace sodium cyanide in gold leaching process and showing good application potentials.
