Foundry silica sand is the quartz as the main mineral composition, particle size of mm to mm refractory particles, according to the mining and processing methods of different can be divided into artificial silica sand and sand washing, sand washing, selection of natural silica sand such as sand (flotation).
Mineral ProcessingThe end product of mechanical mineral processing is an ore concentrate which is then put through a metallurgical process. Hydrometallurgy, pyrometallurgy or a combination of the two are used to "refine" the concentrate by detaching the atoms of the target elements from the crystal lattice at the atomic level. These metallurgical techniques have much in common with .
BAUXITE AND ALUMINA TESTINGGenerally, about 85% of the bauxite ore is alumina and can be processed to produce aluminum. To obtain alumina from the raw bauxite ore, a wet chemical caustic leach method known as the Bayer process is employed. This resulting alumina is further processed to .
