Comprehensive Recovery of Clean Technology from Alrali Wastes and Suifur Dioxide in Antimony Smelting

Antimony smelting arsenic -alkali residue through leaching, absorption of alkaline solution containing arsenic with emissions of sulfur dioxide, sodium sulfide and other sulfide solvent for removing arsenic, and with ferric sulfate for the depth of the removal of arsenic, purification and concentration and drying process, arsenicalkali residue of difficult to handle and low content of sulfur dioxide emissions are thorough treatment. The treatment in the whole process, recycling rate of antimony is 99%, and open circulation rate of arsenic is over 90%, sulfur dioxide by absorbing is more than 95%, the gas for emission reach the standard, and alkali transformed into Sodium Sulfite. Waste in Antimony smelting reached comprehensive treatment, and is a clean process.
