摘要:

采用环保型非氰浸金剂,结合全泥炭浆法浸出工艺,对甘肃某金矿的浸金工艺进行了研究。具体考察了溶氧量、矿浆浓度、pH值、矿物粒度、浸金剂用量、浸出温度和浸出时间对金浸出效果的影响,采用原子吸收分光光度计测定原矿和尾矿中的金含量,通过计算金浸出率来确定适宜的浸金工艺条件。结果表明:综合考虑经济和浸出率等因素,在矿浆浓度为40%、pH=11~12、浸金剂用量为300 g/t矿样、浸出温度为20~40 ℃及浸金时间为24 h的条件下,用自来水作溶剂在敞开环境下浸金,浸出效率最佳,金的浸出率可达80%。

Abstract:

Abstract: The leaching process of a gold mine in Gansu Province was studied by using environment-friendly non-cyanide gold leaching agent combined with all-sliming carbon-in-pulp process.The effect of dissolved oxygen,pulp concentration,pH value,mineral particle size,leaching agent amount,leaching temperature and leaching time on leaching efficiency of gold were investigated in details.The gold content in ore and tailings was determined by Atomic Absorption Spectrophotometer,and the appropriate gold leaching process conditions were determined by calculating gold leaching rate.Considering the economic cost of process,leaching efficiency and other factors,the results show that the feasible process conditions are as follows:concentration of the pulp is 40%,pH=11~12,leaching agent amount is 300 g/t mineral,leaching temperature is 20~40 ℃,leaching time is 24 h,with water as solvent in open environment.Under these conditions,gold leaching rate reaches 80%.

Key words: gold leaching process, leaching rate, gold, environment-friendly gold leaching agent, all-sliming carbon-in-pulp process, Atomic Absorption Spectrophotometer
