The results, high-quality fine ore powders, are known as fines. Magnetite is magnetic, and hence easily separated from the gangue minerals and capable of producing a high-grade concentrate with very low levels of impurities. Iron ore mining - Malvern Panalytical,To efficiently process iron ore for high quality steel production, frequent ore grade monitoring, during all steps of downstream processing, is mandatory. Independent from the ironmaking method, the optimal use of fuels and energy during sintering, pelletizing and direct reduction of iron ore (DRI) needs to be applied to stay competitive and,
