The rotary furnace is not only the core equipment in the high-temperature reduction smelting process, but also the key hub for promoting the efficient and environmentally friendly transformation of antimony resources, especially the transformation into high value-added products such as antimony trioxide.

The main process flow of pyrometallurgical and electrolytic refining of antimony ore is introduced in detail.

Refining process from crude antimony to antimony ingot and antimony trioxide

This process skillfully combines the essence of pyrolysis and electrolysis, taking advantage of their strengths and avoiding their weaknesses, demonstrating significant technical and economic advantages.

The core advantages of using rotary furnace pyrometallurgy to produce Sb2O3 from antimony ore are high recovery rate, continuous operation, relatively easy control and relatively reasonable energy consumption.
