Potassium Amylxanthate (PAX) CAS 2720-73-2: Comprehensive User Guide

1. Product Overview & Specification Comparison

Potassium Amylxanthate (PAX) (CAS 2720-73-2) is a xanthate derivative widely used as a flotation reagent in mineral processing. Key parameters include:

2. Detailed Applications

PAX is primarily employed in:

• Sulfide Ore Flotation: Selective collector for copper, zinc, and lead sulfides.
• pH Adaptation: Effective in pH ranges of 6-12.
• Analytical Chemistry: Chelating agent for metal ion detection.
• Corrosion Inhibition: Temporary protection in industrial systems.

3. Usage Scenarios

Copper Concentrate Production

Step 1: Grind ore to 75μm.

Step 2: Add PAX (50-150g/ton) and frothers.

Step 3: Achieve 85-92% copper recovery.

Zinc-Pyrite Separation

PAX dosage of 80-120g/ton enables efficient sphalerite activation while depressing iron sulfides.

4. Real Client Case Studies

Case 1: GreenMine Tech Co. (Chile)

Challenge: Low copper recovery (78%) in porphyry ore.

Solution: PAX at 110g/ton with pH 10.5 adjustment.

Result: Recovery increased to 89% with 24% concentrate grade.

Case 2: GlobalMetals Corp. (Canada)

Challenge: Zinc-iron separation inefficiency.

Solution: PAX/pH-controlled staged flotation.

Result: Zn grade improved from 42% to 54% with 8% Fe content.
