摘要:
针对碳酸盐、砷和铜含量高的“三高”金矿选矿回收难度较大的问题,采用原矿焙烧脱碳除砷—NH4Cl“闪速”浸钙—(NH4)2SO4浸镁铜—非氰浸剂药剂(swust-1)浸金工艺流程综合回收矿石中有价元素。研究结果表明:当焙烧温度为950 ℃、焙烧时间为2 h、矿浆浓度为30%、-0.074 mm粒级含量为70%、NH4Cl浓度为3.0 mol/L和浸出时间为10 min时,矿石中Ca2+、Mg2+和Cu2+浸出率分别为82.88%、20.12%和16.75%;在(NH4)2SO4浓度为2.5 mol/L、矿浆浓度为30%和浸出温度为50 ℃的条件下,经过“两段”浸出,Mg2+和Cu2+浸出效果较好。经过“焙烧—浸钙镁铜”后,金的浸出率也大大提高。通过上述工艺流程处理后,钙、镁、铜和金的总浸出率分别可达96.18%、95.16%、80.51%和78.86%,提高了高碱性含铜金矿中有价元素浸出率和综合经济价值。
