一、前言铜冶炼的原料一般是硫化物矿石或精矿,在冶炼时通过氧化将硫部分除去或完全除去,以获得中间产物,例如:焙砂、烧结块、冰铜或粗铜,同时放出SO_2气体。因此,在这样的冶金过程中,大都涉及气氛中的氧和硫以及SO_2的化学反应。通常可以认为属于Me—O—S及其它造渣成分组成的体系。logP_(O_2)—logP_(S_2)图是以各种化学反应达到 I. Preface The raw materials for copper smelting are generally sulfide ores or concentrates. The sulfur is partially removed or completely removed by oxidation during smelting to obtain intermediate products such as calcine, sinter cake, matte or blister copper SO 2 gas. Therefore, in such metallurgical processes, the chemical reactions of oxygen and sulfur in the atmosphere and SO2 are mostly involved. It is generally considered to be a system consisting of Me-O-S and other slagging components. logP_ (O_2) -logP_ (S_2) plots are achieved by various chemical reactions
