Abstract:The traditional zinc hydrometallurgy process has problems such as high flue gas treatment cost and low comprehensive recovery rate. In recent years, oxygen pressure leaching technology has been applied to the zinc smelting industry due to its advantages of strong adaptability to raw materials, high zinc recovery rate, and low environmental pollution. The production process of zinc concentrate oxygen pressure leaching was introduced. The basic principle of the leaching process reaction was discussed, and the influence and mechanism of ion catalysis, temperature, acidity, dispersants and other conditions on ion behavior during the leaching process were analyzed. The leaching behavior of accompanying elements such as Fe, Ga, Ge, In, and Ag in zinc concentrate and their changes under different leaching conditions were discussed.
