Sustainable Mining and Metallurgy

In this paper, the principle of drying wet materials by microwave dryer and the properties of arsenic trioxide were studied to demonstrate the feasibility of microwave dryer drying arsenic trioxide. By introducing the overall structure of the microwave dryer, the advantages and disadvantages of the microwave dryer in the production of arsenic trioxide were expounded, and the operation parameters and drying effect of the microwave dryer were explored through trial production. The trial production showed that the arsenic trioxide microwave dryer had the characteristics of high quality, high efficiency, energy saving and environmental protection, and the production effect was good.
