摘要
以复杂铜钴矿浸出溶液为原料,采用M5774萃取铜,硫酸反萃,铜的萃取率和反萃率均大于99%,萃余液用SO_2/空气混合气氧化中和除铁、锰,除铁后液铁和铝均小于0.005g/L,锰没有完全除掉,采用活性氧化镁沉淀镍和钴,在较优条件下,镍、钴沉淀率分别为97.73%和94.33%,用活性氧化钙沉淀锰和镁。
Extraction and stripping ratio of copper is 99% above applying leaching solution of complex copper and cobalt ores as raw material,M5774 as extractant,and sulfuric acid as stripping agent.Iron and aluminum in residual raffinate are both 0.005g/L below combined with incompletely removed manganese after removal of iron and manganese by oxidation of SO_2/air mixture gas.Nickel and cobalt precipitation rate is 97.73%and 94.33%respectively under the optimum precipitation conditions with active magnesium oxide.Manganese and magnesium are precipitated by active calcium oxide.
