某复杂含多金属硫化矿金矿石综合回收试验研究

Experimental research on integrative recovery of a complicated polymetal gold ore

对河南某复杂含多金属硫化矿金矿石进行了选矿试验研究,采用部分混合浮选—铅铜分离浮选—尾矿浮选硫工艺流程,获得含金银的铜精矿、铅精矿和硫精矿;最后的浮选尾矿通过重选获得钨精矿。试验采用的工艺流程综合回收了金、银、铜、铅、硫、钨,选矿指标理想。

Floatation experimental research is carried out on a certain complicated gold ore containing mixed sulphides in Henan province. With partial mixing floatation, led copper separation floatation and sulfur floatation from tailings process, copper concentrate, lead concentrate and sulfur concentrate as gold carriers are obtained. Tungsten concentrate is acquired by refloatation of tailings. The experiments recover gold, silver, copper, lead, sulfur and tungsten integratively. Meanwhile, the floatation indices are ideal.
