low grade iron ore for chromite

Chromite an overview ScienceDirect Topics

In Aladag (Adana, South Turkey) a low grade chromite deposit (5.42% Cr 2 O 3 grade) with 200160metric tons reserve has yet to be exploited. The produced chromite ore is consumed mostly by the iron steel (about 85%) and chemical industries (about 15%) (Yalcin, 2003).

Iron ore pricing explained Metal Bulletin

Inter grade price spreads tend to expand during these times, and high grade indices such as the MBIOI 65 BZ and Metal Bulletin 66% Fe Concentrate Index (MBIOI CO) usually extend their premiums to the MBIOI 62 and Metal Bulletin 58% Fe Iron Ore Index (MBIOI 58). Conversely, when margins fall away, mills look to the cheaper low grade ores to reduce costs and minimize their production rates.
