Ready-to-use litharge, borax, soda ash, silica and reducing agent blend for fire assay fusion.
Fusing crushed ore samples; cupellation preparation; precious metal grade determination.
A pre-blended mix of litharge, borax, soda ash, silica, and a reducing agent, formulated for the fusion stage of fire assay.
Consistency. A fixed, repeatable formulation removes batch-to-batch weighing variance, which matters because fire assay results depend on complete, consistent lead collection during fusion.
Assay labs and mine-site laboratories that need to determine precious metal grade in ore samples, including gold and silver.
High-purity yellow-to-red PbO, manufactured in-house for fire assay flux and flux-grade use.
Strong alkali for pH control and ore leaching, supplied as flakes, pearls, or solution.
Balanced xanthate collector for Cu, Pb, Zn and Au-bearing sulfide flotation.
