中文摘要: 针对某含铜氧化金矿开展高氰高碱综合回收金铜试验。结果表明,在矿石细度-0.074 mm占93.54%、氰化钠浓度1 000 mg/L、矿浆浓度40.00%、浸出时间48 h、炭用量10 g/L的条件下,金浸出率为89.67%,炭金品位313.20 g/t,铜品位1 304.48 g/t。炭浸贫液通过酸化法脱铜回收氰根,氰根回收率超过99%,同时铜以品位超过60%铜精矿回收。
Abstract:Comprehensive recovery of Cu and Au from a copper-oxide gold mine was studied under condition of high sodium cyanide and alkali. The results show that gold leaching rate is 89.67% with charcoal gold grade of 313.20 g/t and copper grade of 1 304.48 g/t under the conditions including ore fineness of -0.074 mm of 93.54%, sodium cyanide concentration of 1 000 mg/L, pulp density of 40.00%, leaching time of 48 h, and carbon dosage of 10 g/L. Cyanide recovery is 99% above and copper grade in copper concentrate is 60% above from CIL poor liquid by acidification process.
