黑龙江某金矿选矿试验研究

Experimental research on beneficiation of a golg mine in Heilongjiang

黑龙江某金矿矿石中硫化物较少,金矿物以粒间金及空洞边部金为主,属于易加工易选冶矿石。通过研究认为全泥氰化—炭浆吸附提金工艺在该矿有较好的应用前景。使用全泥氰化—炭浆吸附提金工艺流程,在磨矿粒度-200目占90%,氰化时间24小时,金浸出率:95.62%,金的回收率为95.38%。

Heilongjiang sulfide in certain gold ore is less; gold content is given priority to with intergranular gold and hole edge gold, belongs to the ore mineral smelting and processing easily. By study the mud - carbon plasma adsorption of gold cyanide process has good application prospect in the mine. Use all shme cyanidation - carbon slurry process for adsorption of gold, the gri＇nd size - 200 eyes （90%）, cyanide time 24 hours, the gold leaching rate： 95.62%, the gold recovery rate is 95.38%.
