Stainless steel industry consumes about 80% of ferrochrome produced (mainly high-carbon/charge grade). Chromite varies widely in composition according to the chemical formula (Mg, Fe +2) (Cr, Al, Fe +3) 2 O 4.Metallurgical Grade Chrome Ore Concentrate — Clover Alloys,Prior to being consumed in steelmaking, chrome ore must be smelted in an electric furnace together with a carbon reductant, which eliminates most of the impurities in the ore and produces a product known as ferrochrome. Ferrochrome is an alloy containing 48-75% chromium, 0-8% carbon and 0-6% silicon, with most of the remaining content being iron.

Ore is lighter, and so it comes on the surface and impurities are left behind. 6. Roasting and calcination: In metallurgy, the process of heating a concentrated ore in the presence of oxygen is known as roasting. This process is applied in the case of sulfide ores.

Pyrometallurgical Process an overview ScienceDirect Topics

Industrial processes for recovering metals from e-waste are based on combined pyrometallurgical, hydrometallurgical, and electrometallurgical routes. In pyrometallurgical processes, e-waste is blended with other materials and incorporated into primary/secondary smelting processes (e.g., into Cu or Pb smelters) at 1200°C (Table 3.3). CuRecycling and environmental issues of metallurgical slags,Recycling of different metallurgical slags Slags from ferrous metallurgical industry In general, steel production has the following two routes: using iron ore as raw material in Blast Furnace(BF) for ironmaking, basic oxygen steelmaking (BOF) for steel converting, and secondary metallurgical process Chromium processing The metal and its alloys Britannica,Chromium processing Chromium processing The metal and its alloys: By far the greatest use of chromium is as a ferrochromium alloying agent in steel manufacture. Pure chromium is added to nonferrous alloys and is also applied as a corrosion-resistant surfacing for other metals. Chromium surfaces are produced on other metals by electroplating and chromizing.
