Every physical characteristic your application depends on — particle size, dissolution rate, purity — is set during manufacturing, not sorted afterward.
Copper input is sourced and verified before it enters the reaction stage — the starting point that determines the purity ceiling of everything downstream.
Controlled reaction with sulphuric acid converts raw copper into copper sulphate solution under monitored temperature and concentration.
The solution is crystallised under controlled cooling conditions — this stage is where crystal size begins to be shaped, not corrected later.
Crystals are separated from the mother liquor, isolating the product from residual solution and soluble impurities.
Controlled drying brings moisture content down to the level your application's shelf life and handling requirements need.
Crystals are screened into defined particle-size grades — powder through large crystal — so the size on the spec sheet is the size in the bag.
Every batch is tested against Cu%, moisture, insolubles, and the relevant impurity profile before it's cleared to ship.
Packed to export-ready standard, with the documentation — COA, SDS, and application-specific paperwork — matched to the shipment.
Because we control every stage from raw copper to packed crystal, we can hold a grade to a specification — not just sort a generic batch into rough size categories after the fact. That's the difference between a supplier and a manufacturer.
