Applications
⚒️ Mineral Flotation
Isopropyl Ethyl Thionocarbamate is primarily used as a selective collector for:
-
Copper sulfide ores
-
Lead-zinc sulfide ores
-
Molybdenite (MoS₂)
-
Silver-bearing sulfides
It is often applied in complex ore flotation circuits where selectivity over pyrite and iron sulfides is necessary. IPETC works effectively at low dosages, making it both cost-efficient and environmentally preferable.
🧪 Reagent Blending
Due to its chemical stability, IPETC is also used in custom flotation reagent formulations, where it is blended with xanthates or dithiophosphates to enhance flotation performance.

-
✅ High Selectivity: Excellent for separating valuable sulfides from gangue minerals
-
✅ Versatile pH Range: Works well in both alkaline and mildly acidic environments
-
✅ Low Dosage Requirement: Effective even at minimal concentrations
-
✅ Good Compatibility: Can be combined with other flotation agents for enhanced effect
-
✅ Stable and Safe: Lower toxicity and environmental impact compared to other collectors
Handling and Storage
-
Store in a cool, dry, and well-ventilated place
-
Avoid contact with strong oxidizing agents
-
Use protective gloves and eyewear during handling
-
Keep containers tightly sealed to avoid contamination
Conclusion
Isopropyl Ethyl Thionocarbamate (IPETC) is a powerful flotation agent that has proven its value in enhancing the yield and quality of non-ferrous mineral extractions. With its excellent selectivity, high performance, and adaptability, IPETC remains an essential chemical in modern mineral processing operations. Whether you’re optimizing copper, lead, zinc, or silver recovery, IPETC delivers the efficiency and reliability that industries demand.
