Ferrochrome (FeCr) is the main source of 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 …

The beneficiation process aims to increase the iron content and reduce impurities in the ore, resulting in a higher-quality concentrate suitable for further processing and utilization. The specific beneficiation method employed depends on factors such as the mineralogy of the ore, the presence of specific impurities, and the desired iron content.
