Abstract

In this work, we focus on the up-gradation of the copper ore of Qilla Saifullah in Pakistan through the froth flotation technique. The chemical analysis of the head copper ore sample reveal the presence of 2.85% Cu, 22%  Fe2O3, 52.9% SiO2, and other minor minerals. The optimum grinding time and liberation size of the copper ore have been determined as 30 minutes and +149-105 µm, respectively, for further processing. The chemical reagents are optimized in order to get a maximum grade and recovery of the copper ore. After comparisons and analysis of the results obtained, it can be concluded that the maximum grade and recovery of the copper ore are achieved at the dosage 300 (g/t) of the collector potassium amyl xanthate (C6H11KOS2), 250 g/t of pine oil, 250 g/t of a depressant (Na2SiO3), conditioning time of 10 minutes for a collector, flotation time of 6 and 10 minutes, and pH of 10 using the froth flotation technique.
Froth浮选技术提高齐拉赛富拉铜矿品位工艺参数的优化
本文采用泡沫浮选技术对巴基斯坦齐拉赛夫拉铜矿进行了上级配研究。对原矿铜矿样品的化学分析表明,存在2.85%的Cu、22%的Fe2O3、52.9%的SiO2和其他次要矿物。已确定铜矿石的最佳研磨时间和释放尺寸分别为30分钟和+149-105µm,以供进一步加工。为了获得最大的铜矿品位和回收率,对化学试剂进行了优化。对所得结果进行比较和分析后,可以得出结论,在捕收剂戊基黄原酸钾(C6H11KOS2)300(g/t)、松油250 g/t、抑制剂(Na2SiO3)250 g/t,收集器的调节时间为10分钟,浮选时间为6和10分钟,使用泡沫浮选技术的pH为10。
