Chrome ore is rock that includes a high enough concentration of chromite to possess financial worth.Chromite may be the principle ore with the element chromium.Chromite is actually a essential industrial mineral utilised for manufacturing stainless steel as a result of its vey high melting point.
Chromite ore may be the key supply of chromium metal, chemical and refractory market. Depending on particular physical and chemical properties, the ore is categorized for diverse user industries.Through the beneficiation of chromite ore, about 50% of the total feed is discarded into tailing which consist of substantial quantity with the chromite values inside the ultra-fine size. Most of the heavy minerals like chromite are treated in gravity concentration at unique stages of upgradation. The popularity of gravity concentration is because of their simplicity, low operating price and ease of operation.
Chromate production from chromite ore is definitely an crucial standard metallurgical method but is usually a supply of serious pollution. The regular chromate production process utilised in China presently consists of three procedures: roasting of chromite ore, water leaching, and multi-stage evaporation and crystallization.Within the method of roasting, chromite is mixed with sodium carbonate in addition to a significant amount of limestone and dolomite additives, and after that calcined at 1200 in a rotary kiln.The utilization of reagents and power inside the calcination approach is very low. In certain, a big level of chromium-containing residue, chromite dusts and waste gases are discharged from chromate plants, which outcomes in severe pollution complications around the globe.Together with the adjust of reaction medium, the new approach achieves higher resource and energy utilization efficiency. In the identical time, the new method also changes the physical and chemical properties of other elements co-existing inside the chromite ore. The procedure supplies the possibility for virtually comprehensive utilization of chromite and zero emission of residue. Hence, the clean production of chromate is often realized.
This project is located in the Malay nicaea, mobile crushing mainly for the production of architectural sand aggregate screening system, the project by my company with Singapore T joint implementation process design, equipment manufacture, system installation and debugging, the system training delivery operation, this project because of considering the customer's periodic construction, at the same time in order to improve the efficiency of system installation, saving the cost of investment, the system is broken unit and screening unit adopts the tyre mobile solutions.Because the material source of the project is coarse aggregate produced by the original mine jaw broken by the customer, the project is designed with two-stage crushing and screening sections of medium and fine crushed cone, and equipped with vehicle-mounted container centralized control room.
Customer demand: 200 tons per hour

Introduction to Dolomite
Dolomite crystal belongs to carbonate mineral of trigonal series, including iron dolomite and manganese dolomite. Its crystal structure is like calcite, and is usually rhombohedral.Dolomite is mainly composed of calcium carbonate and magnesium carbonate. This stone appears to be very close to limestone in appearance. In fact, dolomite is often found in areas where limestone deposits are found.Dolomite can be widely used in building materials, ceramics, glass and refractories, chemical industry and agriculture, environmental protection, energy conservation and other fields.Moreover, the production of Dolomite ore in China is very large, which can not only meet the needs of relevant industrial production, but also has been exported abroad, and shows a good development trend.
