摘要
镇源金矿的炭质板岩型矿石与其它矿石类型比较,具有原矿品位低,且选矿回收率和精矿品位均较低的特点。为了综合利用,特加强对它的试验研究。本文主要进行了几个条件试验,包括:调整剂用量试验(CMC、腐植酸钠、硅氟酸钠)、石灰用量试验、丁基钠黄药用量试验、磨矿细度试验和几个流程试验。最后选定了二粗一扫两精流程,得到37.88g/t的精矿品位和78.89%的回收率,取得了较好的经济指标和技术指标。
The Carbonaceous slate ore in Zhenyuan Gold Mine is of lower grade and the concentrate grade and recovery are lower compared with other ore type. For comprehensive utilization, beneficiation tests have been carried out from aspects of CMC, sodium humate, sodium fluosilicate, lime and sodium butyl xanthate dose; ginding size and processing flowsheet. The final flatation circuit with two roughing stages, one scavenging and two cleaning stages has been selected, and the technical and economical indexes are good with concentrate grade of 37.88g/t and recovery of 78.89%.
