加强充气搅拌预氧化可将含金硫化矿在磨矿过程中产生的、对氰化浸出有害的难免离子氧化成对氰化浸出无害的离子，同时在磁黄铁矿和白铁矿颗粒表面生成Ｆｅ（ＯＨ）３薄膜，阻止了它们的进一步溶解，从而大大提高了金银的氰化浸出率。某浮选金精矿预氧化处理后，金银的浸出率分别达到９８．９％和９２．５％。 Strengthen the aeration mixing pre-oxidation can be produced in the gold sulfide ore grinding process, cyanide leaching is harmful to the inevitable ion oxidation of cyanide leaching of non-harmful ions, while in the pyrrhotite and iron oxide particles on the surface Generate Fe (OH) 3 film, preventing their further dissolution, thus greatly improving the gold and silver cyanide leaching rate. After a flotation gold concentrate pre-oxidation treatment, the leaching rates of gold and silver reached 98.9% and 92.5% respectively.
