摘要:

某低品位铜钼矿石中主要有价元素为铜和钼,铜、钼矿物嵌布粒度细,与脉石矿物复杂共生,但辉钼矿与黄铜矿主要嵌布在脉石矿物裂隙,有利于矿物的单体解离。在矿石工艺矿物学研究的基础上,探索了铜钼选别工艺,在最佳试验条件下,采用铜钼混合浮选工艺获得的混合精矿钼品位0.470 0 %、铜品位3.100 %,钼回收率可达76.22 %、铜回收率高达89.29 %;混合精矿铜钼分离,钼精矿钼品位49.390 0 %、钼作业回收率66.18 %,铜精矿铜作业回收率99.98 %。

Abstract:

The main valuable elements in a low-grade copper-molybdenum ore are copper and molybdenum.The copper and molybdenum minerals are finely embedded,associated in a complex way with gangue minerals,while moly-bdenite and chalcopyrite are mainly embedded in the fissures of gangue minerals,which is beneficial to the monomer disintegration of minerals.Based on the process mineralogy study,the separation process for molybdenum and copper is explored.Under optimal test conditions,the bulk flotation process of copper and molybdenum can obtain the mixed concentrate with molybdenum grade 0.470 0 %,copper grade 3.100 %,molybdenum recovery rate as high as 76.22 %,copper recovery rate as high as 89.29 %;the copper and molybdenum separation of the mixed concentrate can obtain the molybdenum concentrate with molybdenum grade 49.390 0 % and molybdenum operation recovery rate 66.18 %,and the copper concentrate with copper operation recovery rate 99.98 %.
