Purechem fire assay fluxes are manufactured from high purity raw materials with gold and silver values as low as 1.5ppb and lower. We manufacture and supply both lead-based flux and Nickel fluxes. Our premium nickel sulphide fluxes are NIMAC (for high grade concentrates) and FATNIS (for low grade feeds and tails). These fluxes are robust and eliminates the need for double fusion (Slag washing). Most importantly, the fluxes are optimized to suite different material types viz. Merensky, UG2 and Platreef sample types.
Purechem has the ability to manufacture customized flux which are tailored to suit your specific requirements.
