Chromite ore is primarily used as the main raw material for the production of chromium metal and its compounds. The vast majority of chromite ore is used in the production of ferrochrome, which is an essential ingredient in stainless steel. Ferrochrome provides the corrosive resistance properties to stainless steel.
Chromite is the most important chromium ore mineral. It forms a complete solid solution series with many other members of the group, eg. in the Chromite-Hercynite Series, Chromite-Spinel Series, Chromite-Magnetite Series and the Chromite-Magnesiochromite Series.It is the iron analogue of Zincochromite, Cochromite, Manganochromite and Magnesiochromite and the Cr …
The most important use of chrome is in production of high-strength alloys and alloys which are heat, abrasion, corrosion and oxidation resistant. Approximately half of all chromite production goes into the manufacture of stainless steel. …
Chrome ore magnetic separation Chrome ore has weak magnetism.Therefore, magnetic separation would be a good choice for separating it. Low-intensity magnetic separation: This method is used to get rid of magnetite, increasing the Cr/Fe ratio and selecting the qualified chrome concentrate. This method means a lot to the unqualified chrome concentrate after …

Because chrome is a very hard metal and has a low coefficient of friction, chrome plating was also used for extending the life of parts that receive heavy wear, such as automobile cylinders, and was useful in boiler pipes to prevent build-up of scale (mineral deposits). Refractory materials are highly resistant to heat and are chemically stable.
Ferrochrome is created with iron, chrome, and oxygen. The high-grade chromite ore to be taken from the Ring of Fire area is grinded and put through a processing plant that requires high levels of energy to melt the ore and add carbon to separate the oxygen from the iron and chrome. The completed iron and chrome product is called ferrochrome.
