A new magnetic separator design with transverse magnetized disk permanent magnet is proposed in Calculation of magnetic field using finite element method. The results show that the maximum value of the force factor (about T2/m)Achieved in areas with the highest magnetic density. Analysis as a publication It has been shown that the calculation of the gap magnetic field between the working poles of the magnetic separator is a rather complicated task. For most magnetic system configurations, it has not been resolved until now, and the experimental method is quite laborious.

The space distribution of magnetic flux density in the working area of magnetic separator is designed. Survey materials and results. The influence of the structure of the magnetic system on the magnetic field topology is studied, and a new design of the disk separator is carried out Proposed by the author of the paper.
In this case, the adjacent coils that form the spiral with its spacing also maintain the same distance. Through this configuration of the magnetic systemCleaning the working surface of the disk from the extracted ferromagnetic inclusions greatly simplifies the process of unloading them without stopping the separation process. Fig. 1 shows the fragmentation of the spiral disk separator system containing four ring magnets, indicating the main design parameters :--air gap; a--

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.
Selected quality quartz as materials, combined with advanced ceramic processing workmanship, mainly used for melting platinum, gold, silver, copper and another high temperature alloy, high purity, anti-corrosion, anti strong acid and strong alkali, good hardness, high thermal shock resistance. The main component is SiO2 ≥80%, Al2O3 (≤17%) and other is 3%( K2O, Na2O, Fe2O3), There is no crack after 10 times sudden heat and sudden cold at 1100℃⇌ 20℃, and no crack after 10 times using oxygen cutting gun to spray 1700-1800 flame on the crucible.

The fire assay method is a classic analysis method that applies the principles and techniques of metallurgy to analytical chemistry, and is one of the oldest methods in analytical chemistry.
The fire assay method is to quantitatively determine the content of precious metals by adding flux to smelt ores and metallurgical products.
