MINING APPLICATION

MINING REAGENT GRADE

Froth flotation activator for sphalerite. Lifts zinc recovery from below 50% to above 80% in rougher circuits. Engineered for mine-site conditions.

YOUR CIRCUIT HAS A RECOVERY PROBLEM. PURE Cu FIXES IT.

Sphalerite is naturally reluctant to float. Without proper copper activation, zinc recovery in rougher circuits routinely sits below 50% — leaving significant value on the table. PURE Cu Mining Reagent Grade is a specialised copper sulphate pentahydrate engineered specifically for froth flotation activation and hydrometallurgical refining. Low insolubles, rapid dissolution, and predictable dosing make it the reagent of choice for complex polymetallic circuits.

CIRCUIT ACTIVATION GRID

Surface Activation
Copper ions form a reactive sulphide film on sphalerite
Collector Attachment
Xanthates bind firmly to the activated surface
Recovery Lift
Rougher circuit recovery climbs from <50% to 80%+
Grade Optimisation
Depresses unwanted pyrites and gangue
