Abstract: In the research of biological oxidation gold pretreatment to recovere gold from the cold and high areas in Xinjiang, a gas-liquid mixing phase density model by the mechanism modeling method was established. By the calculation of the gas-liquid mixing phase density in the oxidation tank, the fitting curve that the influence of environment temperature, atmospheric pressure and mass concentration to mixture density was resulted, and the oxidation tank equipment improvement was developed. The results show that there are direct proportion relationship between mixture density with environment temperature and mass concentration. But there are inverse proportion relationship between mixture density and atmospheric pressure. This modified oxidation tank equipment can improve the reaction speed and efficiency of biological oxidation reaction.
