1974—1979年期间,印度铬铁矿矿石的开采量一直徘徊在266到500千吨之间。但是铬铁合金的生产1979年却达22168吨。看来铬铁合金产量增长与印度1977年禁止高品位铬铁矿石出口有关。奥里萨邦有两个企业进行生产,每一个企业铬精矿年生产能力约50000吨(铬精矿含Cr_20_3 55—60％,Si4％,Cu 8％,P 0.04％)。预计低品位矿石将扩大使用。 During 1974-1979, the amount of chromite ore mined in India has been hovering between 266 and 500 kt. However, the production of ferrochrome reached 22,168 tons in 1979. Ferrochromium production appears to be related to the ban on high-grade chromite exports in India in 1977. There are two enterprises in Orissa producing about 50,000 tons of chrome concentrate per year (Chromium concentrate contains 55-60% Cr_2O_3, Si4%, Cu 8%, P 0.04%). Lower grade ore is expected to be expanded.
