  • Difference Between Hematite And Iron Ore

    Anshan type lean hematite ore, located in Anshan area of northeast China, is one of the mostly typical iron ores of super-large reserve. In the past, this low-grade iron ore was crushed and classified into coarse and fine fractions, with the coarse fraction reductively roasted and the fine fraction processed in a gravity-high-intensity magnetic separation-flotation flowsheet.
