Chrome ore is mainly used in metallurgy, refractory and chemical industries, the proportion consumption of chrome ore in the metallurgy industry accounts for more than 80% [1, 2], and With the rapid development of stainless steel industry, this proportion will further increase [3]. In China, the chrome ore is mainly imported
chromium ore is defined as crude ore with average content of 45% Cr 2O 3 or chromium concentrate obtained by beneficiation. Chromium ore is widely used in metallurgy, chemistry, and refractory materials. Thus, based on elemental composition and industrial use, chromium ores are also classified into three types (Nacy, 1992): high-chromium …
