Product Description

Product Description

Assay Flux

Flux 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.

 

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. 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.

Company Profile

 

Hebei Fiza Technolory Co., Ltd, is a professional manufacturer of assay litharge, assay flux, crucible (Clay crucible, Ceramic Crucible), Magnesia cupel and Magnesia Bulion Block and with perfect management system and mature production technology.

The crucible, cupel and other fire assay consumables are made of high quality raw materials, high temperature resistance, good thermal conductivity, high melting purity, strong corrosion resistance and long service life.

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.  

Our staff of sales and technical support is available to help you in selecting the right protection for your application as well
as to provide you with samples of our products for evaluation. At High Five, we are committed to providing the highest level of customer service, competitive pricing, speedy delivery and a comprehensive, cutting-edge product offering. Our ultimate goal is your satisfaction.
