摘要
对某碳质氧化金矿进行了矿石性质研究,用次氯酸钙对碳质矿进行适度地化学氧化,破坏或平定有害的碳组分,用氰化法提金,在原料磨矿粒度为-0.075 mm粒级占90%时,浸出48 h,最终获得浸渣金品位0.18 g/t、浸出率92.86%的较好指标。
After the study on the ore properties of a carbonaceous gold ore,calcium hypochlorite was selected for a moderate chemical oxidation of the ore and to destroy or annul harmful carbonaceous components,the oxidized ore was extracted with cyanide,and with a raw ore grinding fineness of-0.075 mm of 90% and a leaching time of 48 h,a final leaching residue with a leaching yield of 92.86% and a gold content of 0.18 g/t can be produced.
