摘要
对某含砷含银复杂难选铜铅锌硫化矿进行了浮选试验研究。使用新型高效硫化矿捕收剂CYC和环保型铅抑制剂CYZ,采用粗磨⁃铜铅混合浮选⁃分级再磨⁃脱药⁃铜铅分离工艺流程,获得了铜品位22.42%、银含量11549.74 g/t,铜、银回收率分别为73.77%、83.85%的铜精矿,以及铅品位13.96%、锑含量6.61%,铅、锑回收率分别为19.45%、11.10%的铅精矿,实现了铜和铅的高效分离,伴生银、锑也得到了有效回收。
Flotation tests were conducted for a complex refractory copper⁃lead⁃zinc polymetallic sulfide ore bearing arsenic and silver.By using a new high⁃efficient sulfide ore collector(CYC)and an environment friendly lead depressant(CYZ),the test with a flowsheet consisting of rough grinding,copper⁃lead⁃silver bulk flotation,classification and regrinding,reagent removal and Cu/Pb separation produced a copper concentrate grading 22.42% Cu and 11549.74 g/t Ag with corresponding recoveries of 73.77% Cu and 83.85%Ag,as well as a lead concentrate grading 13.96% Pb and 6.61% Sb with corresponding recoveries of 19.45%Pb and 11.10% Sb.It is shown that with this technique,an efficient Cu/Pb separation can be actualized,while the associated Ag and Sb minerals can also be reclaimed effectively.
