Core Process Route

The antimony smelting process employs pyrometallurgy, using antimony ore as the raw material. Reduction smelting in an antimony smelting furnace yields crude antimony. This crude antimony is then fed into a refining furnace, where oxygen blowing induces oxidative volatilization; this separates the antimony in gaseous form, simultaneously producing molten pure antimony and antimony-bearing flue gas.

Product Output Path

Antimony Ingots: The refined molten metal is transferred to a chain-type casting machine for automatic casting and molding, producing industrial-grade antimony ingots.

Antimony Oxide Powder: The antimony-bearing flue gas is cooled and condensed within cooling ducts, then efficiently recovered using a multi-stage bag-type dust collection system to yield antimony oxide powder.

Environmental Protection Systems

Following dust collection, the flue gas enters a desulfurization tower spray system to remove acidic gases such as sulfur dioxide, ensuring clean emissions that meet environmental standards.

Process Advantages

This process achieves both efficient resource recovery and clean production, and is the mainstream technology route in the current antimony smelting industry. From the reduction smelting in the antimony smelting furnace to refining, dust collection, ingot casting and tail gas treatment, the entire chain is closely connected, providing a reliable technical guarantee for the stable production of antimony products.
