摘要
本文对原矿含砷0.65%,矿石氧化率为99.9%的难选氧化金矿石进行了浮选和氰化研究.浮选获得了金精矿含金品位285g/t,金回收率70.82%,砷脱除率达98.78%的浮选指标.氰化取得了浸出率99.37%的优异指标.
In this paper, studies are conducted on flotation and cyanidation of arsenic-bearing and oxidized refractory gold ore whose oxidation ratio and content of arsenic are 99.9% and 0.65% respectively. Through flotation, the gold concentrate with the grade of 285g/t is obtained, the recovery of gold reachesto 70.82% and the ratio of arsenic removal attains to 98.78%. Furthermore, the cyanide leaching rate of gold come up to 99.37% that is known as the excellent result.
