Iron Ore Processing Crushing Grinding Plant Machine
Iron ore is the key raw material for steel production enterprises. generally, iron ore with a grade of less than 50% needs to be processed before smelting and utilization. after crushing, grinding, magnetic separation, flotation, and gravity separation, etc., iron is gradually selected from the natural iron.
Iron processing - iron processing - ores: iron ores occur in igneous, metamorphic (transformed), or sedimentary rocks in a variety of geologic environments. most are sedimentary, but many have been changed by weathering, and so their precise origin is difficult to determine. the most widely distributed iron-bearing minerals are oxides, and iron ores consist mainly of hematite (fe2o3), which is.
