珊瑚矿桕浮硫化矿分离选矿试验研究

摘要

Sulphide ores which outputs by desulphurization from selected sets of floating coral mining, contain copper, zinc, sulfur, arsenic, tungsten, tin and other useful minerals. Copper and zinc concentrate which contains copper 23.85%, 90.02% copper recovery and zinc 45.02%, 85.18% zinc recovery, respectively were available obtained by separation beneficiation test in the condition of grinding fineness-0.074mm accounted for 83%, using the first copper after zinc flotation process.%珊瑚矿精选桕浮脱硫产出的硫化矿，含有铜、锌、硫、砷、钨、锡等有用矿物。经选矿分离试验，磨矿细度-0．074mm占83％的条件下，采用先铜后锌的优先浮选流程，可获得含铜23．85％、铜回收率90．02％的铜精矿和含锌45．02％，锌回收率85．18％的锌精矿。
