Accurate control of the oxidation process and reliable equipment for the collection process are essential conditions for obtaining high-quality antimony trioxide powder.

The core purpose is to remove harmful impurities such as sulfur, iron, lead, arsenic, etc. remaining in crude antimony to obtain high-purity metallic antimony,

Pyrometallurgy is the mainstream process for extracting metallic antimony, and optimizing its technical process is of great significance for improving energy efficiency and achieving green production.

The direct discharge of high-temperature and complex flue gas produced by the rotary furnace in antimony ore pyrometallurgy can cause pollution and waste. Establishing an efficient flue gas treatment process is the key to green smelting, standard emissions, and resource utilization.

The importance of rotary kilns is reflected in three aspects.

In the antimony metallurgical industry, the refining furnace is a key piece of equipment for purifying crude antimony.
