Taking copper sulphide mineral as study objects, the studies of chalcopyrite heating and pressure pre-oxidation leaching process were conducted in acid system adding chloride.
以硫化铜矿物为研究对象，在添加氯盐的酸性体系中，开展了黄铜矿加温、加压预氧化浸出过程研究。
The process is acid adding pre-leaching at normal pressure, pressurized oxygen leaching to leach out base metals and filtering separation to obtain solid noble metal concentrate.
其特征在于 采用常压加酸预浸、再加压氧浸出，将羰化合成残渣中的贱金属浸出，过滤分 离得到固体贵金属精矿。
