1. Overview of the Core Purpose

High-temperature reduction smelting of ore powder in a rotary furnace is mainly intended to reduce the antimony oxides in desulfurized ore powder to metallic antimony, producing crude antimony and providing raw material for subsequent refining and product manufacturing.

2. Specific Process Objectives

Under high-temperature reducing conditions, the antimony oxides in the ore powder react with a reducing agent, and the antimony is reduced to the metallic state, forming crude antimony. This process achieves the preliminary extraction and enrichment of antimony and is a key stage in the antimony smelting process.

3. Significance for Subsequent Production

The resulting crude antimony can serve as raw material for the refining stage and, after further purification, be used for product manufacturing. Therefore, high-temperature reduction smelting in the rotary furnace directly affects antimony recovery and subsequent product quality, and is an important step connecting desulfurized ore powder processing with refining production.

Conclusion

In summary, high-temperature reduction smelting in the antimony rotary furnace takes the reduction of antimony oxides to metallic antimony as its core objective. It achieves both the preliminary extraction and enrichment of antimony and provides a guarantee for subsequent refining and product quality, making it an important transitional stage in the antimony rotary furnace smelting process.
