Mining Grade CMC: High-Performance Depressant & Binder for Mineral Processing

Introduction: Trusted CMC Partner for Mining Excellence

Qingdao Unionchem Co.,Ltd. is a leading manufacturer of mining-grade Carboxymethyl Cellulose (CMC), engineered for flotation separation and iron ore pelletization. With ISO 9001 and REACH certifications, our CMC meets global mining standards for selectivity, strength, and environmental safety. As the global mining chemicals market grows at 6.8% CAGR (2025–2032), we deliver 2,000 MT annually to 20+ countries, empowering clients like Vale and Rio Tinto to achieve 15% higher mineral recovery and 20% lower binder costs.

Product Portfolio: Tailored for Mining Applications

Grade	Viscosity (1% Solution, cps)	Degree of Substitution (DS)	Key Applications
IL9 (Low Viscosity)	20–50	0.7–0.9	Flotation depressant for talc, calcite separation
M2 (Medium Viscosity)	100–300	0.8–1.0	Iron ore pellet binder, silica depression
MG (Granular)	20–300	0.7–1.0	High-dispersion flotation systems, continuous dosing

Technical Advantages: Boosting Efficiency & Sustainability

1. Superior Flotation Selectivity

• Gangue Depression: Selectively inhibits calcite, talc, and silica with 0.05–0.2% dosage, increasing concentrate grade by 8–10% .

• pH Stability: Effective in pH 7–10, compatible with fatty acid collectors and frothers.

2. High-Strength Pellet Binding

• Green Pellet Strength: 0.1% addition increases compressive strength to 3.5 kg/pellet, reducing breakage during transport by 40% .

• Low Impurity: SiO₂ content <0.5%, eliminating the need for flux additives in blast furnaces.

3. Eco-Friendly & Cost-Efficient

• Biodegradable: 80% degradation in 28 days, meeting EU Mine Waste Directive 2006/21/EC.

• Low Dosage: 30% lower consumption than traditional depressants (e.g., water glass), reducing chemical costs by $0.5–$1.2/ton ore processed.

Industry-Specific Solutions

Iron Ore Processing

• Flotation: M2 grade depresses silica in hematite ore, increasing Fe recovery from 65% to 72% (Case Study: Brazilian Iron Mine, 2024).

• Pelletization: MG granular grade improves fired pellet strength to 2500 N/pellet, enabling 15% higher throughput in induration furnaces.

Base Metal Mining

• Copper-Zinc Separation: IL9 grade selectively depresses sphalerite, achieving Cu concentrate purity >25% with 90% recovery.

• Tungsten Scheelite Flotation: Enhances WO₃ grade from 0.5% to 55% by depressing calcite and fluorite.
