Product Description

DESCRIPTION

Assay Litharge is a special type of Lead Oxide used for gold and other precious metal ore analysis.  It is made from specially refined lead and offers a very low level of precious metal impurities

Our litharge is  premium quality. We guarantee gold levels are<2ppb in all litharge and guarantee silver levels are <0.2ppm in our silver free/assay grade litharge. 

Fire Assay Flux is used in geochemical assay laboratories for detection of gold in ore samples. we are the Chinese premier manufacturer and supplier of quality, gold free flux and litharge. Our quality system guarantees the levels of gold in the fire assay flux are less than 1-1.5ppb in the litharge component of the flux, making it ideal for low level assay work.
