Experimental study on beneficiation of a lead-zinc ore
An The experimental study on the beneficiation process of a lead-zinc ore shows that the lead-zinc grade of the ore is high,the sphalerite distribution is uneven,the middle and fine particles are dominant,the lead-zinc minerals are closely related,and the lead-zinc separation is difficult The experiments of grinding fineness of lead roughing,regrinding fineness of lead roughing concentrate,lead roughing lime,lead roughing lime,lead roughing HB26,lead roughing HB535,lead roughing HB165,lead finishing I lime,lead finishing I HB26,lead finishing I HB535,zinc roughing 2#Oil,zinc finishing I lime and zinc finishing I butyl yellow were carried out,the lead grade 64.80%,the zinc content 7.07%,the lead recovery 93.67%,the zinc grade 50.11%,the lead content 0.98%and the zinc recovery 88.47%were obtained in the principle flowsheet,sulfur concentrate grade 50.02%,sulfur recovery 35.23%of the test indicators.
