摘要/Abstract

摘要： 以赞比亚某低品位难处理铜钴矿石为研究样本，采用全湿法冶金方法，开展新工艺研究.研究可知:矿石Cu，Co和S质量分数分别为1.270%，0.071%，0.022%.矿石中铜矿物主要为假孔雀石和少量的孔雀石.钴矿物主要为钴锰矿和水钴矿，在褐铁矿和黑云母晶体中有少量铜、钴，矿石中铜钴元素赋存状态极其复杂.最佳的浸出条件为粒度小于74μm的矿粒所占比例70%、浸出温度65℃、浸出时间4h、矿浆质量分数30%、硫酸加入量55kg·t^-1.该条件下铜浸出率可达74.34%左右，钴浸出率可达43.32%左右.充分利用萃余液中的硫酸可降低酸耗，硫酸用量减少20%以上.在搅拌浸出过程中加入适量还原剂Na₂SO₃或FeSO₄，可将钴的浸出率从43%提高到78%.

Abstract: The features of low grade refractory copper-cobalt ores from Zambia were investigated and a novel hydrometallurgical process for them was provided. The results show that the contents of Cu， Co and S in the ores are 1.270%， 0.071% and 0.022%， respectively.Copper element is mainly in the pseudomalachite ore， while only a small amount is in the malachite. Cobalt element is mainly in the cobalt-manganese and heterogenite ores. There are also a small amount of copper and cobalt found in the limonite ore and biotite crystals. Therefore，the presence of copper and cobalt elements in the ore is very complex. In the process ，the optimum leaching conditions are as follows: the ore particles less than 74μm are 70%， the temperature is 65℃， the leaching time is 4h， the pulp density is 30%， and the amount of sulphuric acid is 55kg·t^-1 ore. Under such conditions， the leaching rate of copper and cobalt can reach about 74.34% and 43.32%， respectively.The sulfuric acid consumption can be reduced more than 20% by the replacement of the raffinate. The addition of the reducing agent Na₂SO₃ or FeSO₄ can increase the cobalt leaching rate from 43% to 78%.
