processing consists of crushing and grinding raw materials, followed if necessary by size classification and raw materials calcining and drying. The processed raw material then may be dry-mixed with other minerals and chemical compounds, packaged, and shipped as product. All of these processes are not required for some refractory products.
Another oxide usually found in refractories is the oxide of calcium (lime). Fire clays are also widely used in the manufacture of refractories. Refractories must be chosen according to the conditions they face. Some applications require special refractory materials. Zirconia is used when the material must withstand extremely high temperatures.
Although the technology is already widely applied to base metal concentrates and ferrochrome products, ceramic filtration has only been applied in the iron-ore …

The use of thiosulfate to extract gold from refractory ores is promising because of its non-toxicity and high selectivity. Sulfide minerals (i.e., pyrite, arsenopyrite, chalcopyrite), major gold carriers in refractory gold ores, however, hinder gold extraction due to the high consumption of a lixiviant. In this study, a new method to improve gold …
Chemical mineral processing is a process in which the useful components in mineral raw materials are enriched or purified to obtain concentrates or separate products by using the difference of chemical properties between minerals and chemical processing or chemical processing and physical beneficiation combined.
When flotation of various non-ferrous metal sulfide minerals (such as copper, lead, zinc, etc.) with xanthate collectors, the ore usually contains a certain amount of iron sulfide minerals, such as pyrite, marcasite, pyrrhotite, arsenopyrite, etc., inhibiting iron sulfide minerals with lime helps the target minerals to float.
