某高硫铜硫矿工艺矿物学研究

研究了某高硫铜硫矿的工艺矿物学。结果表明,原矿中铜品位为2.85%,硫品位为24.32%,金含量为0.48g/t,铜、硫、金是主要回收的元素。原矿中的金属矿物有黄铜矿、黄铁矿、蓝辉铜矿。目的矿物黄铜矿和黄铁矿的嵌布粒度差异较大,且铜矿单体解离度相对较差。在选择工艺流程时应该注重氧化铜矿物的回收,同时要选择合适的磨矿细度,保证目的矿物单体解离。

Study on Mineralogy of a High Sulfur Copper Sulfur Ore Process

This paper studies the process mineralogy of high - sulfur copper - sulfur ore. The results show that: the copper grade in the raw ore is 2.85%, the sulfur grade is 24.32%, the gold content is 0.48g/t, is the main recovered element. The metallic minerals in the primary ore are chalcopyrite, pyrite and digenite. The chimeric grain size of chalcopyrite and pyrite are different, and the dissociation degree of copper monomer is relatively poor. Therefore, attention should be paid to the recovery of copper oxide mineral when selecting process flow, at the same time, the proper grinding fineness should be selected to ensure the dissociation of the target mineral monomer.
