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.

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.
