iron ore fines processing

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 ironbearing minerals are oxides and iron ores consist mainly of hematite Fe2O3 which is

Processing All of the ore mined at Malmberget is crushed and screened and is then upgraded using magnetic separation technology Concentrator output is then processed to give sinter fines olivine pellets or concentrate for iron powder production In 2004 LKAB announced a 350m investment in a third pelletising plant for Malmberget

Impurities in hard rock and unconsolidated rock processing such as iron ore mostly consist of clayey and loamy components which are fine particles with a grain size of smaller than 0063 mm They are either loose or bonded between the usable particles agglomerates binders and coatings of concrescences in the raw material

Screening is the passing of material through definite and uniform apertures is the only true and accurate means of grading to a required particle size Air separation and hydraulic classification depend upon gravity and particle shape and result in the segregation and retention of material of higher specific gravity and lower surface area irrespective of size

Our heavyduty iron ore balling drums are relied on by some of the industry’s top producers to process iron ore fines into pellets for the steelmaking process The use of a disc pelletizer is a popular alternative approach to pelletizing iron ore fines as this offers more control over pellet size and produces a more refined pellet product
