Product Description

Sodium Isobutyl Xanthate (SIBX) is a widely used and highly efficient flotation collector for various nonferrous metallic sulfide ores, including copper, lead, zinc, and pyrite. Its strong collecting ability and selective performance make it an indispensable reagent in modern mineral processing circuits. This article provides a detailed overview of the properties, applications, handling practices, and storage guidelines for SIBX.

 

1. Product Overview

• Chemical Classification: Sodium Organic Salt
• CAS Number: 25306-75-6
• Appearance: Pale yellow to yellow-green granules or free-flowing powder
• Purity: Available in 85% and 90% minimum grades
• Free Alkali: ≤ 0.2% Max
• Moisture & Volatile Matter: ≤ 4.0% Max
• Shelf Life: 12 months under proper storage conditions

SIBX is specifically formulated to act as a strong collector in flotation processes, where it demonstrates excellent performance in both natural circuits and high-alkali environments.

 

2. Application and Advantages

Primary Use:
SIBX is primarily used as a collector in the flotation of:

• Copper Sulfide Ores
• Lead-Zinc Sulfide Ores
• Pyrite

It is particularly effective in natural flotation circuits and can enhance recovery rates of valuable minerals even in complex ores.

Advantages of SIBX:

1. Strong Collecting Power:

   • SIBX is highly effective at attaching to sulfide mineral surfaces, ensuring the recovery of copper, lead, and zinc ores.

2. Selective Flotation:

   • Offers excellent selectivity, allowing for minimal interference from unwanted minerals while improving concentrate purity.

3. Wide pH Range Compatibility:

   • Functions efficiently across various pH levels, providing flexibility in flotation operations.

4. Versatile Feeding Method:

   • SIBX is typically prepared as a 10-20% solution for easy addition to flotation circuits.

5. Cost-Effective:

   • Lower dosage requirements (10-100 g/ton) reduce overall reagent consumption, making it a cost-effective choice for mineral processing plants.

 

3. Mechanism of Action

Sodium isobutyl xanthate works by forming a hydrophobic layer on the surface of sulfide minerals. This enhances the adhesion of air bubbles to the target minerals, enabling their selective flotation to the surface. Its strong chemical affinity for sulfide ores ensures:

• Efficient Recovery: Maximizes the extraction of valuable minerals.
• Separation of Pyrite: SIBX can suppress or separate pyrite under controlled conditions, improving the grade of the final concentrate.

 

4. Handling and Safety Guidelines

Storage Requirements:

• Store SIBX in tightly sealed original containers under cool, dry conditions.
• Avoid exposure to sources of ignition, such as open flames or high-heat environments.

Handling Precautions:

• Use protective equipment:
  • Gloves
  • Safety glasses
  • Non-sparking tools
• Ensure proper grounding of electronic equipment to prevent static discharge.
• Avoid inhaling dust or vapors, and always work in a well-ventilated area.

Explosive Environment Precaution:
Due to its flammable nature, SIBX should not be handled near sources of ignition. Special measures should be taken in explosive-prone work environments to prevent static buildup and accidental ignition.

 

5. Environmental Considerations

SIBX, like other xanthates, must be managed responsibly to minimize environmental risks:

• Residue Management: Unreacted SIBX residues should be treated and neutralized before being released into the tailings system.
• Water System Protection: Prevent direct discharge of SIBX into natural water bodies, as it may impact aquatic ecosystems.
• Waste Disposal: Follow regional guidelines for hazardous chemical waste disposal.

Proper management of SIBX ensures compliance with environmental safety regulations while supporting sustainable mining practices.

 

6. Packaging and Transportation

Available Packaging Options:

1. Steel Drums:

   • UN-approved 110 kg net weight steel drum (134 drums per 20'FCL; total 14.74 MT)
   • UN-approved 160 kg net weight steel drum (80 drums per 20'FCL; total 12.80 MT)

2. Wooden Box:

   • 850 kg net jumbo bags inside UN-approved wooden boxes (20 boxes per 20'FCL; total 17 MT)

Transportation Precautions:

• Avoid violent impacts or rough handling during shipping to prevent leaks or contamination.
• Maintain compliance with international hazardous material shipping regulations.

 

7. Conclusion

Sodium Isobutyl Xanthate (SIBX) is a robust and versatile collector for sulfide ores, particularly effective in copper, lead, and zinc flotation processes. Its strong collecting power, cost efficiency, and compatibility with varying flotation conditions make it an essential reagent in mineral beneficiation.

By following proper handling, storage, and environmental safety guidelines, SIBX contributes to efficient mineral recovery while supporting sustainable operations in the mining industry.
