摘 要：采用氯盐溶液对七宝山多金属硫化精矿进行了一系列的浸出试验。比较了不同浸出剂组成的浸出效果和浸出时溶液的电位变化。试验结果表明,含 Cu2+离子的浸剂特别适于浸出含锌的复杂硫化矿。用 CuCl2+FeCl3溶液进行二段递流浸出,浸出率大都在95%以上。文中对所得结果作了讨论。
Abstract: A series of leaching experiments were carried out for Qibaoshan polyme- tallic pyritic sulfide concentrate by using chloride solutions.Lixiviants of va- rious compositions used,the leaching effects and potential changes of solution were compared.Test results showed that the lixiviants containing cupric ion were particularly applicable to leaching zinc-bearing complex sulfide concetrates.In two-stage counter-currnt leaching with CuCl2+FeCl3 solution,the extraction rate of most metals was above 95%.The results ob- tained were discussed.
