摘要
对青海某铅锌矿进行了浮选药剂制度优化研究。结果表明,采用新型螯合剂PT-8配合常规25^(#)黑药可有效强化铜铅硫化矿物的浮选回收,新型捕收剂SXF-10可以在低用量条件下高效回收矿石中的铁闪锌矿,明显提高铜、铅和锌金属的浮选回收率;在磨矿细度-0.074 mm粒级占70%条件下,铅浮选采用25^(#)黑药+PT-8,锌浮选采用SXF-10,闭路试验可获得Cu品位3.52%、Cu回收率70.08%、Pb品位62.53%、Pb回收率93.75%的含铜铅精矿以及Zn品位48.19%、Zn回收率87.97%的锌精矿。
The flotation reagent system was optimized for a lead-zinc ore in Qinghai based on experimental studies.It is shown that a new chelating agent(PT-8)combined with the conventional 25^(#)xanthate can effectively enhance the flotation recovery of copper-lead sulfide minerals.A new collector(SXF-10)at a low dosage can efficiently recover marmatite from the ore,significantly improving the recoveries of Cu,Pb and Zn from flotation process.With raw ore at a grinding fineness of-0.074 mm 70%,25^(#)xanthate and PT-8 are used for Pb flotation,and SXF-10 is used for Zn flotation.A closed-circuit test with such process flow can produce a Cu-Pb concentrate grading 3.52%Cu and 62.53% Pb at corresponding recoveries of 70.08% and 93.75%,respectively,and a Zn concentrate grading 48.19%Zn at 87.97%recovery.
