Chromite - Wikipedia
90% of mined chromite ore is used for stainless steel production. Chromite ore production has been on a steady incline, which causes a rise in demand for the stainless steel markets. Nichrome alloys. Chromite, when alloyed with iron and nickel creates an alloy called nichrome. Nichrome is described as being 80% nickel and 20% chromium.

SOME ASPECTS OF THE PRODUCTION OF FERROCHROME …
In the conventional production of stainless steels, chromium is generally introduced to the process in the form of Cr-Fe-C-Si alloys, principally as high-carbon ferrochrome or charge chrome. The level of carbon and silicon in the above alloys is important especially when refining is carried out by blowing oxygen in the melt.
The impact of platinum production from UG2 ore on ...
the latter process, even more UG2 can be used due to the higher chrome recovery of the process. The pellets are fed in various forms, including prereduced, sintered/pre-oxidized, cold or preheated, to a SAF. In terms of DC-arc furnace smelting, the process is inherently suitable for the use of UG2 ore.
Optimization of Process Parameter for Smelting and ...
quality raw materials (chromite ore, coke) for production of Ferro-chrome imposed the new challenges for the Ferro-chrome industries to deal with [2]. Therefore, an attempt have been made in the present investigation to optimize the process parameters for production of high grade Ferro-chrome
Chromium - Wikipedia
For the production of pure chromium, the iron must be separated from the chromium in a two step roasting and leaching process. The chromite ore is heated with a mixture of calcium carbonate and sodium carbonate in the presence of air. The chromium is oxidized to the hexavalent form, while the iron forms the stable Fe 2 O 3.
