| 摘 要： | 针对金以显微自然金形态包裹于黄铁矿和毒砂中,传统浸出提金工艺难以有效回收的含金硫精矿,进行深度精选,降低其钙、镁、硅、铝等的含量,并获得高硫(50.18%)、高铁(43.97%)的含金硫精矿.再对深度精选获得的高品位硫精矿的氧化过程进行理论分析和试验研究,结果表明,砷黄铁矿的氧化反应需要在相对较弱的氧化气氛和550%的...

| Abstract: | For the gold is wrapped by pyrite and arsenopyrite in the form of microscopic native gold,it was difficult to recovery gold-bearing pyrite concentration by traditional cyanation process.Further concentration was applied to reduce the impurity contents,such as calcium,magnesium,silica and aluminum gangue,and then high-purity of auriferous pyrite concentrates with sulfur 50.18% and iron 43.97% was obtained.Through the theoretical and experimental research on the auriferous pyrite concentrate in oxidation,the ... |
