Ethyl Thiocarbamate/ Sodium Diethyl

Description Chemical Identity & Description Product Name: Ethyl Thiocarbamate / Sodium Diethyl Dithiocarbamate Chemical Formula: (C₂H₅)₂NCSSNa Synonyms: Sodium Diethyldithiocarbamate, DEDTC CAS Number: 148-18-5 Molecular Weight: 179.26 g/mol Appearance: Yellowish to amber liquid or solid powder (depending on form) Solubility: Fully soluble in water Odor: Characteristic, slightly sulfurous Ethyl Thiocarbamate is typically supplied as a liquid or water-soluble salt, ensuring rapid dispersion in flotation circuits. It enhances the hydrophobic properties of sulfide minerals, allowing for better attachment to air bubbles during flotation. Technical Specifications   Property Specification Purity ≥ 95% (typical commercial grade) pH (1% Solution) 9.0 – 11.0 Density (25°C) 1.00 – 1.10 g/cm³ Solubility in Water Complete Form Liquid or crystalline solid Shelf Life 12 months (stored in original packaging) Packaging 200 kg drums or 1000 kg IBC containers Applications ⛏️ Mining and Mineral Processing Ethyl Thiocarbamate is primarily used in the flotation of: Copper sulfide ores Lead and zinc ores Polymetallic and complex sulfide ores Gold and silver-bearing ores It acts by forming stable, hydrophobic complexes with metal ions on mineral surfaces, improving recovery rates and concentrate grades even in low pH or high salinity environments. Advantages ✅ High Selectivity: Targets desired minerals while minimizing gangue flotation ✅ Efficient Collector: Requires low dosage for effective flotation performance ✅ Good Froth Stability: Supports froth formation, enhancing flotation recovery ✅ Compatible with Other Reagents: Can be blended with xanthates or other thiol collectors ✅ Lower Environmental Impact: Biodegradable formulation with reduced toxicity Storage & Handling Storage Conditions: Store in cool, dry, and well-ventilated spaces Precautionary Measures: Avoid contact with acids and oxidizing agents Personal Protection: Use gloves, goggles, and protective clothing Disposal: Follow local environmental regulations and SDS guidelines Conclusion Ethyl Thiocarbamate / Sodium Diethyl is a versatile and powerful flotation collector designed to optimize the recovery of metal sulfides and precious metals. Its high selectivity, low dosage requirement, and stable frothing ability make it a preferred choice in modern mineral processing operations. Whether used alone or in combination with other reagents, it provides a cost-effective and environmentally friendlier solution for ore beneficiation.
