摘要: 对安徽某高砷高硫难处理金矿进行了详细的矿物学研究,在此基础上提出了磁重联合试验方案,并通过磁选入选细度、磁场强度、重选入选细度等条件试验,最终得到含硫36.11%,含砷0.03%,回收率为17.81%的合格硫精矿及含金16.84g/t,含砷13.63%,金回收率为47.63%的金精矿。

Abstract: The detailed mineralogical study about a high arsenic & sulfur-containing gold ore is carried out,and based on this,a magnetic separation-gravity joint test process is proposed.After the conditioning tests of grinding size for magnetic separation,magnetic strength,fineness for gravity separation etc.,the qualified sulfur concentrate with a 17.81% of recovery containing 36.11% of sulfur and 0.03% of arsenic,and gold concentrate with a 47.63% of recovery containing 16.84% of gold and 13.63% of arsenic are obtained.

Key words: Refractory gold ore, Process mineralogy, Gravity concentration
