  • Efficient extractant for copper/zinc oxide ores through chelation mechanisms
  • Primary reagent in tin ore beneficiation when combined with P86 modifier

2.2 Analytical Chemistry

  • Precipitation agent for bismuth, copper, and nickel analysis
  • Colorimetric determination of tungsten and rare earth elements

2.3 Industrial Synthesis

  • Key intermediate in pharmaceutical hydroxamate derivatives
  • Precursor for corrosion inhibitor formulations

3. Operational Guidelines

3.1 Mineral Processing Protocol

  1. Prepare 0.5-1.0% alkaline solution (pH 8.5-10)
  2. Dose at 100-500g/ton ore depending on metal content
  3. Maintain slurry temperature between 25-40°C
  4. Combine with P86 modifier (1:3 ratio) for tin ore applications

3.2 Safety Handling

  • PPE Requirements: Chemical-resistant gloves, goggles
  • Storage: Dry environment below 30°C
  • Disposal: Neutralize with lime before wastewater discharge

4. Industry Case Studies

Case 1: Rare Earth Recovery Enhancement

Client: Southern China Rare Earth Group
Challenge: Low recovery rates (≤65%) for cerium oxides
Solution: Implemented SHAM-based flotation at pH 9.2
Outcome: Recovery improved to 82% with 94% purity

Case 2: Tin Concentrate Optimization

Client: Yunnan Tin Corporation
Challenge: High cassiterite losses in tailings
Solution: SHAM/P86 synergistic system (1:3 ratio)
Outcome: Tin recovery increased 18% versus traditional methods
