Melting and casting crude antimony into qualified anode plates is a key step

As a key piece of equipment in antimony smelting, the rotary kiln exhibits fundamental differences in chemical purpose, temperature, and atmosphere control between its oxidation roasting and reduction smelting stages.

In high-temperature treatment processes such as antimony smelting, the stable operation of rotary kilns is crucial as the core equipment.

In the pyrometallurgical antimony refining process, after obtaining crude antimony metal, the production process enters the refining stage and splits into two independent paths, producing the final antimony ingot and antimony trioxide powder respectively

The core purpose of high-temperature roasting of antimony ore at 800-900 ℃ in a rotary kiln is "desulfurization".

Main equipment in the production process of antimony trioxide
