| 摘 要： | 青海省某低品位浸染型辉钼矿矿石，原矿钼品位为0.21%，铅品位为0.0049%，针对该低品位钼矿石开展了工艺矿物学研究以及可选性条件实验。采用柴油作钼的捕收剂、水玻璃作为调整剂，经过了一段粗选五段精选二段扫选的浮选工艺流程，所得的钼精矿经检测Pb含量为0.98%，影响其销售价格。针对该含铅超标的钼精矿采用了再磨脱药以及添加抑制铅的抑制剂磷诺克斯相结合的工艺流程，钼精矿的含铅量从0.98%降低至0.074%，钼品位由原矿的0.21%提高到53.95%，钼回收率达到了90.18%，实现了钼的有效回收。

| Abstract: | The molybdenum grade is 0.21% and the lead grade is 0.0049% in a low grade disseminated molybdenite ore in Qinghai Province. Process mineralogy research and beneficiability condition test were carried out for the low grade molybdenum ore. Diesel oil was used as collector and sodium silicate was used as regulator. After flotation process of one stage roughing, five stages cleaning and two stages scavenging, the Pb content of molybdenum concentrate obtained was 0.98%. The sale price of molybdenum mines was affected due to exceed standards lead levels. In order to reduce the lead content of the molybdenum concentrate, the process of regrinding and detoxification combined with the addition of phosphoknox, an inhibitor of inhibiting lead, was adopted for the molybdenum concentrate containing excessive lead. Finally, the lead content of molybdenum concentrate was reduced from 0.98% to 0.074%, molybdenum grade is increased from 0.21% to 53.95%, molybdenum recovery reached 90.18%, realizing effective recovery of molybdenum. |
