Description

Starch Xanthate is a chemically modified starch derivative, produced by reacting starch with carbon disulfide under alkaline conditions. This modification imparts unique properties, making it a valuable functional polymer for industrial applications where controlled rheology, binding, or flocculation is required. It is primarily utilized in the mining, wastewater treatment, and paper manufacturing industries.

Application

• Mining & Mineral Processing: Acts as a selective depressant and flocculant in the froth flotation process for the separation of sulfide ores.
• Wastewater Treatment: Used as an effective, biodegradable flocculating agent for the removal of suspended solids and heavy metal ions from industrial effluents.
• Paper Industry: Functions as a wet-end additive to improve retention, drainage, and the strength properties of paper sheets.
• Textile Processing: Employed in sizing and finishing operations to modify fabric handle and as an auxiliary in dyeing processes.
• Soil Stabilization: Serves as a temporary binding agent in erosion control and dust suppression applications.
• Ceramics & Drilling Muds: Used as a rheology modifier and binder in ceramic slips and water-based drilling fluid formulations.
