Product Description: Potassium Amyl Xanthate (PAX) is a highly effective collector used in the froth flotation process of sulfide ores in the mining industry. It is the potassium salt of aliphatic xanthic acid, renowned for its selectivity and effectiveness in promoting the separation of valuable minerals from gangue.
Key Features:
- High Efficiency: PAX exhibits strong collecting properties, significantly enhancing the selective flotation of sulfide minerals.
- Selective Flocculation: Provides selective flocculation capabilities, enabling the separation of minerals based on their hydrophobicity.
- Versatility: Compatible with various ore types and can be seamlessly used in combination with other flotation reagents for customized separation processes.
- Environmental Consideration: Biodegradable and less toxic compared to some other xanthate collectors, making it a safer choice.
Applications:
- Froth Flotation: Primarily used in the flotation of non-ferrous and precious metal sulfide ores, such as copper, lead, zinc, and others.
- Mineral Processing: Improves the efficiency of mineral beneficiation processes, leading to higher recovery rates and enhanced purity of the end product.
Safety Information:
- Handle with care, wearing appropriate personal protective equipment (PPE), including gloves, safety goggles, and a mask.
- Avoid contact with skin and eyes. In case of contact, flush immediately with plenty of water and seek medical advice if necessary.
Storage Conditions:
- Store in a cool, dry, and well-ventilated area away from direct sunlight and heat sources.
- Keep containers tightly sealed to maintain product integrity and prevent contamination.
Regulatory Information:
- Complies with relevant industry standards and regulations for use in the mining and mineral processing sectors.
