Flotation Applications
Sodium Isobutyl Xanthate is used to improve mineral hydrophobicity and support froth flotation recovery in sulfide ore systems. It is commonly evaluated for:
- Copper sulfide flotation
- Lead-zinc sulfide ore beneficiation
- Gold-bearing sulfide ore flotation
- Plant trials comparing collector strength, selectivity and reagent dosage
For related flotation collectors and frothers, compare Sodium Ethyl Xanthate, Sodium Isopropyl Xanthate, Potassium Amyl Xanthate and Methyl Isobutyl Carbinol.
Packaging and Storage
Typical packaging includes 25–50 kg bags, 130 kg iron drums or 850 kg wooden boxes. Store SIBX in a cool, dry and well-ventilated warehouse. Keep containers sealed and protect the product from moisture, heat, direct sunlight, oxidizing materials and acids.
