Lowergrade sources of iron ore generally require beneficiation, using techniques like crushing, milling, gravity or heavy media separation, screening, and silica froth flotation to improve the concentration of the ore and remove impurities. The results, highquality fine ore powders, are known as fines. Magnetite. Magnetite is magnetic, and hence easily separated from the gangue minerals and ...
Sintering is a thermal process (1300 1400 C) by which a mixture of iron ore, return fines, recycled products of the iron and steel industry (mill scale, blast furnace dusts, etc.), slag forming elements, fluxes and coke are agglomerated in a sinter plant with the purpose of
Evolution of binders for iron ore pelletizing Induration technologies Challenges and innovations in iron ore pelletizing 2. Pelletizing process and raw materials The iron ore is mined mostly from open pit deposits through mining operations and the raw product, run of mine, is subjected to mineral processing.
