What Are Activators & Depressants in Flotation?
In flotation systems:
Activators increase mineral floatability
Depressants prevent unwanted minerals from floating
This selective separation is critical when processing complex ores.
Common depressants include starch and dextrin-but more operations are switching to CMC CARBOXYMETHYL CELLULOSE for better stability and selectivity.
Why CMC Carboxymethyl Cellulose Performs Better Than Traditional Depressants
1. Higher Selectivity = Better Concentrate Grade
CMC selectively adsorbs on gangue minerals such as silicates and clays without affecting valuable minerals.
2. Strong Anti-Slime Performance
Fine particles are one of the biggest challenges in flotation.
CMC CARBOXYMETHYL CELLULOSE effectively:
Disperses slimes
Reduces coating on valuable minerals
Improves separation efficiency
3. Stable Performance Across Conditions
Unlike starch:
Works in wide pH range
Consistent viscosity
Less sensitive to process fluctuation
4. Lower Overall Cost in Use
Even if unit price is higher than starch:
👉 Lower dosage
👉 Higher recovery
👉 Less reprocessing
= Lower total cost per ton
Typical Applications of CMC in Mining
CMC CARBOXYMETHYL CELLULOSE FOR MINING INDUSTRY is widely used in:
Iron ore flotation (silica depression)
Sulfide ore processing
Phosphate beneficiation
Gold & complex ores
👉 Works especially well in high-clay or fine-particle systems
How to Choose the Right CMC Grade
Choosing the wrong grade = poor performance.
Key factors:
Viscosity: LV / HV
Degree of Substitution (DS)
Purity level
Particle size (mesh)
We recommend testing based on:
Ore type
Process conditions
Target recovery

FAQ – Mining CMC Application
Q1: What is the typical dosage of CMC in flotation?
Usually between 50–300 g/ton, depending on ore type and process conditions.
Q2: CMC vs Starch – Which is better?
Starch: cheaper but unstable
CMC: higher performance, better selectivity, lower long-term cost
👉 Most modern plants are switching to CMC.
Q3: How to test CMC before bulk order?
We recommend:
Lab flotation test
Compare with current reagent
Adjust dosage
👉 We can provide free samples for testing
