Product Details

Product Introduction

Crucibles with fire assay flux and the sample is put into the fusion furnace. The lead captures the gold, silver and precious metals in the molten state to form a lead alloy (generally called a lead button). The lead alloy due to the high specificity sink to the bottom of the crucible. The base metal oxides and gangue react with fluxes (silica, borax, and sodium carbonate) to form slags (silicate or borate). Slags floats on the crucible due to its small specific gravity. So the gold and silver separate from the sample.

Our standard range of fire assay clay crucibles from 30g to 65g can usually be proceeded 5-times-firing and sometimes can be even repeatedly used in more than 9 times with some formula of flux. This feature provides our customers important benefits of reducing cost per firing and increasing profitability. And we can also design and supply to our customer's individual requirements and specifications in dimensions, shape and so on.

Quality China Fire Assay Crucible Manufacture And Factory Magnesia Cupel for Melting Gold Manufacturer | XTL

6A 7A 8A China Fire Assay Crucible Manufacture And Factory Magnesia Cupel for Melting Gold compared with similar products on the market, it has incomparable outstanding advantages in terms of performance, quality, appearance, etc., and enjoys a good reputation in the market. Xngtailong summarizes the defects of past products and continuously improves them. The specifications of 6A 7A 8A China Fire Assay Crucible Manufacture And Factory Magnesia Cupel for Melting Gold can be customized according to your needs.Cupel is a porous refractory for absorbing lead oxide when ash blows the lead buckle. The main component of magnesia is magnesium oxide, which is a very good refractory and can resist the erosion of alkaline flux. Lead oxide is a very strong alkaline flux. At high temperatures, the affinity between lead oxide and silica is very strong, which can invade the silicate in the cupel. There is more silicate in the ash cupel and cement cupel. After blowing with this kind of cupel, there will be pits on the surface of the cupel, and precious metals will be lost as a result. Using magnesia cupel, no such phenomenon after ash blowing, the surface is very smooth.
