Sodium Hexametaphosphate 68% Mining Flotation Depressant Ore Processing Dispersant Powder
Sodium hexametaphosphate (SHMP) 68% serves as a selective depressant and dispersant in mineral flotation and ore processing. It effectively disperses slime and selectively depresses gangue minerals to improve concentrate grade and recovery.

25 kg polyethylene woven bags with inner liner, or 1000 kg jumbo bags. Delivery within 5-7 working days after payment confirmation.
SHMP is usually added as a 5-10% aqueous solution to the conditioning tank before flotation. Optimal dosage depends on ore type and pulp density.
In many circuits SHMP provides stronger dispersing power; we recommend a small-scale test to confirm performance for your specific ore.
