Product Description
Fire Assay Flux is used in geochemical assay laboratories for detection of gold in ore samples. It is a dry reagent used as a key ingredient in the fire assay process. The composition of the flux should be adapted to suit the matrix of the sample being tested. Fluxes are combined with mineral samples containing precious metals and then heated in a furnace to initiate a fusion process precipitating a Lead (Pb) button. Further treatment of this Lead button through the process of cupellation produces a prill containing the precious metals that were present in the original sample. From this point, the assayer can decide on any number of methods to establish a precise breakdown of the precious metals. This method of mineral testing produces results that are so precise they can be specified in parts per billion.
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.
The raw materials are certified for the use of fire test flow, the main ones are litharge or lead oxide with SGS certified amounts of gold <1 ppb and Silver<1 ppm. In addition is used Borax anhydrous, sodium carbonate, silicon oxide, fluorite, and other elements to order of each customer.
For each batch that is made for a given customer, a counter sample is left, which is kept for three months.
Product Specification
Fire Assay Flux is available with a wide selection of ingredients, although the most common globally are Litharge, Soda Ash, Borax, Baking Flour/Corn meal, Silica Flour and Silver Nitrate. The Litharge is available in both powder and granular form and in different grades of purity to suit your application. Fiza will always provide the ingredients to give you the right result at the lowest possible price.
