赣西北某矿床铜矿石选矿试验研究
|
摘要
以赣西北某矿床的铜矿石为研究对象,根据矿石性质,采用浮选工艺流程选别矿石。在条件试验的基础上,采用"一粗一扫三精"的浮选流程,闭路试验最终得到产率为3.29%的铜精矿,铜精矿中含铜、硫、钼、银分别为16.09%、31.74%、0.19%、124.5×10~(-6),铜、硫、钼、银回收率分别达到92.40%、86.95%、41.98%、51.20%,且铅、锌、砷含量满足铜精矿质量要求,矿石具有较好的可选性。
The copper ore of a deposit in northwest Jiangxi was taken as the research object in this study.According to ore properties,flotation process flow process was selected for ore separation.On the basis of conditional test,the preferential flotation flowsheet closed-circuit test(commonly called "one roughness,one sweep and three essence")was carried,obtained a qualified copper concentrate with final yield of 3.29%,containing copper grade is 16.09%,copper recovery is 92.40%,and silver grade is 124.5×10~(-6),silver recovery is 51.20%.In addition,the content of lead,zinc and arsenic meets the quality requirements of copper concentrate,and the ore has good dressing.
