antimony ore leaching

Extraction of antimony from antimony sulfides bearing solids

When potassium hydroxide solutions are utilized to leach the antimony from the ores, the resulting potassium antimonate is water-soluble and the aqueous mixture resulting from the oxidation is a solution which is substantially free of a solid product. Accordingly, in this instance, sodium chloride is added to precipitate sodium antimonate.
