中文摘要: 针对低品位氧化铜钴矿硫酸体系铜、钴浸出过程，考察了矿石粒度、浸出酸量、SO2用量、液固比、浸出时间对Cu、Co及杂质Fe、Mn、Si的浸出影响规律。并进一步对单因素强化浸出措施进行了经济性分析，最终确定了较优的浸出控制条件，磨矿时间5 min、pH值~1.5、SO2量6.37 kg?t-矿-1、液固比3:1（mL/g)，浸出时间5小时。在该条件下，Cu、Co的浸出率分别为93.67%和75.90%，Mn的浸出率约为87.00%，Fe和Si的浸出率分别为2.66%和0.24%。
Abstract:The effects of ore size, acid dosage, SO2 dosage, liquid-solid ratio and leaching time on the leaching efficiency of Cu, Co and impurities Fe, Mn and Si were investigated during the sulfuric acid leaching process of copper-cobalt oxide ore. Furthermore, the economic benefits of single factor enhanced leaching were analyzed. The optimal leaching control conditions were determined, including grinding time of 5 min, pH value of about 1.5, SO2 dosage of 6.37 kg/ t-ore, liquid-solid ratio of 3:1 (mL/g), leaching time of 5 hours. Under these conditions, the leaching efficiency of Cu and Co were 93.67% and 75.90% respectively, Mn was about 87.00%, and Fe and Si were 2.66% and 0.24% respectively.
