Recommended Dosage
Copper-Molybdenum: 50-200g/t ore
Lead-Zinc Ores: 100-300g/t ore
Nickel Ores: 80-250g/t ore
Potash Flotation: 30-100g/t ore
* Optimal dosage determined by flotation tests. Dosage depends on talc/clay content.
Usage Instructions
Preparation: Prepare 1-2% solution by adding CMC to water with stirring
Mixing Time: Stir for 30-60 minutes until fully dissolved
Addition Point: Add to conditioning tank before flotation
pH Range: Effective from pH 7-11 (optimal: 8-10)
* Add slowly to prevent lump formation. Store in dry place away from moisture.
