China Chrome Ore Processing Plant in Oman

what is chrome?

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.

consist of chromite ore

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.

china chrome ore processing

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.
