An Overview of Currently Applied Ferrochrome Production Processes
Ferrochrome (FeCr) is the main source of virgin chromium (Cr) units used in modern-day chromium (Cr) containing alloys. The vast majority of produced Cr is used during the production of stainless steel, which owes its corrosion resistance mainly to the presence of Cr. In turn, stainless steel is mainly produced from Cr-containing scrap metal The book serves as a guide to mineral processing plant engineers for flow sheet development of various minerals, including coal and steel plant waste. It additionally includes alternative flow sheets and process routes for plant design. Purchase Mineral Processing 1st Edition. Print Book & E-Book.

Efficient utilization of nickel rich Chromite Ore Processing
To enrich the chromite values, researchers have treated the COPT in the different dry and wet beneficiation processes, and the summary of these studies are listed in Table 1.Most of these enrichment routes are stated to produce a marketable chromite-rich concentrate, but it generates more ultrafine tailings, which is again a waste for industry The Steel Policy of India, 2017 aspires to achieve 300 million tonnes of steel-making capacity by 2030. This would translate into additional consumption of manganese and chrome ore other than iron ore as essential raw material for steel making. Similarly, ferro-alloys are one of the important inputs in the manufacture of alloys and On the way up: manganese, chrome ore, and ferro-alloy in
