摘要
对西宁某原生铜矿石进行了选矿试验研究。通过对浮选指标各影响因素的优化,得出了适合铜矿石粗选的最佳工艺条件:磨矿细度70%-74μm的条件下,活化剂Na2S用量120 g/t,组合捕收剂异丙基黄药和丁基铵黑药分别为45、15 g/t,起泡剂11号油23 g/t。在此条件下进行两次扫选,混合精矿进行铜硫分离、再经过三次精选和两次扫选实验室闭路试验,可获得铜精矿品位为18.16%、回收率为86.21%,硫精矿品位为30.12%、回收率为82.07%的较好实验室闭路试验指标。
The beneficiation test of copper ore of Xining was conducted. The optimal roughing conditions achieved by optimizing the influence factors of flotation index were as follows： the ore being ground to the size of 70%-74 μm the dosage of Na2S being 120 g/t as activator, the dosage of combination collectors of isopropyl xanthate and aerofloat being 45 g/t and 15 g/t respectively, the dosage of No.ll pine oil being 25 g/t as frother. Twice scavenging was carried out after roughing h^llowed by the separation of bulk concentrate of copper and sulphur. Through closed-circuit test with triple cleaning and twice scavenging, the copper concentrate grading 18.16% Cu and the sulphur concentrate assaying 30.12% S were obtained, at recoveries of 86.21% Cu and 82.07% S respectively.
