Product information
Zinc sulfate heptahydrate is the seven-water hydrate of zinc sulfate. PubChem confirms CAS 7446-20-0, formula ZnSO4·7H2O and a molecular weight of approximately 287.6 g/mol.
In mineral processing, zinc sulfate is commonly used as a flotation modifier or depressant, particularly in circuits containing zinc-bearing sulfide minerals. Its behaviour depends on pH and the wider reagent scheme. Hamara’s “technical crystal” designation is a commercial-grade description and should be tied to an actual assay, impurity profile and crystal specification before publication.
