But it is used for more than the production of stainless steel and nonferrous alloys; it is also used to create pigments and chemicals used to process leather. Chromite, the only ore of chromium, was first discovered in the United States sometime about 1808 on the farm of Isaac Tyson, Jr., just north of Baltimore, Md. Scattered deposits of ...
Case Study: Chromite mining and health concerns 5 Chromium mining and processing In nature, chromium is found as chromite ore, composed of elemental iron, oxygen and chromium (FeOCr 2 O 3). 1,2 heavily in about a 700 m vicinity around the Countries with commercially significant chromite mines include Russia, South Africa, Zimbabwe, Turkey, the
by the Institute of Process Engineering, at the Chinese Academy of Sciences, and later became a burgeoning treatment process for chromium salt preparation [10,35]. In this process, the chromite suspended in the molten (or sub-molten) alkaline medium is decomposed by oxidation, and then
Refractory manufacturing involves four processes: raw material processing, forming, firing, and final processing. Figure 11.5-1 illustrates the refractory manufacturing process. Raw material processing consists of crushing and grinding raw materials, followed if necessary by size classification and raw materials calcining and drying.

Chromite Wikipedia. Chromite is an iron chromium oxide: FeCr2O4. It is an oxide mineral belonging to the spinel The world's largest chromite mine is South Africa but it is also found in the The two main products of chromite refining are ferrochromium and metallic chromium; for those products the ore smelter process differs considerably.
Chromic oxide (Cr 2 O 3) is an important chemical with numerous industrial applications.The traditional process used for manufacturing chromic oxide from chromite ore has low resources and energy efficiency. Moreover, large quantities of chromium-containing toxic solid wastes are discharged, posing serious pollution concerns.
This process allows chrome recovery in the production of ferrochrome from smelting of chromium ore to be increased from a typical amount of about 70% to 84%, to more than 90%, typically about 95%. This invention relates to a process for recovering ferrochrome alloy and chrome from slag containing entrained ferrochrome alloy and Cr2O3.
Chromite today is mined particularly to make stainless steel through the production of ferrochrome (FeCr), which is an iron-chromium alloy. Chromite grains are commonly found in large mafic igneous intrusions such as the Bushveld in South Africa and Travancore in India.
Chromite ore can be mined to produce chromite concentrate.It can also be crushed and processed. Chromite concentrate, when combined with a reductant such as coal or coke and a high temperature furnace can produce ferrochrome. Ferrochrome is a type of ferroalloy that is an alloy in between chromium and iron. This ferroalloy, as well as chromite concentrate can introduce various health effects.
