Magnetite ore has lower iron content (34-36% Fe) than hematite ore (58-64% Fe). It must be upgraded by a complex ore treatment process (beneficiation) to produce a high-grade (+65% Fe) concentrate for steelmaking. Its magnetic properties enable magnetite to be refined to a premium concentrate product that is globally accepted and highly sought after as to produce high quality, low impurity ...

Deposits of comparatively lower grade iron ore that remain relatively untouched or by-passed, are now most important because of increase in consumer demands. Deposits of comparatively low grade specular hematite amenable to beneficiation by flotation have produced concentrates superior in grade to direct shipping ores. Low grade deposits containing specular hematite (Fe2 O3) as the major iron ...
Metallic iron is virtually unknown on the surface of the Earth except as iron-nickel alloys from meteorites and very rare forms of deep mantle xenoliths. Iron meteorites themselves are thought to have originated from stellar bodies larger than 1,000 km in diameter. The origin of iron can be ultimately traced to formation through nuclear fusion in stars and most of the iron is thought to have originated in dying stars that are large enough to collapse or explode as supernovae. Although iron is the fourth-most abundant element i

23/10/2019 An additional explanation for the iron ore concentrate is its type, which is often classified into two groups: magnetite iron ore and hematite iron ore concentrate. The iron ore product used for concentrating can be either hematite or magnetite. The discrepancy between these two types of iron ore and the different uses of concentrate, which is sometimes for non-steel chains, may cause some ...

Hematite ore magnetic separation process mostly adopts weak-strong magnetic separation process, which is used to treat magnetite-hematite mixed ore. Tailings of low-intensity magnetic separation are sent to strong magnetic roughing and scavenging after thickening, and the strong magnetic roughing concentrate is concentrated and selected by the strong magnetic separator after the thickening.

Hematite is a black, grey or reddish-coloured mineral which is mined as the main source of iron. Hematite has traditionally formed the bulk of global iron ore production, and high-grade hematite is often referred to as “Direct Shipping Ore” or “DSO” because it is mined and beneficiated using a relatively simple crushing and screening process before being exported for use in steel mills.

Unlike hematite ore, magnetite concentrates do not granulate easily at low binder dosage to yield coarser granules due to the absence of nucleus particles. This motivates the present study to harness the complementary properties of hematite ore to enhance granulation of magnetite concentrates via blending. The current state-of-the-art in hematite and magnetite blend granulation is reviewed ...
The study aimed at investigating the chemical composition and microstructure of raw iron ore from the deposits in Muko area (south-western Uganda). The quality of this iron ore was evaluated to establish its suitability to serve as a raw material for iron production. Samples were taken from the six hills of Muko ore deposits and tests carried out to establish their composition and properties.
Several iron ores of different chemical compositions were used in the experimental work including four Chinese (S, Q, H and C) and one European (K) magnetite concentrate and a high-grade Australian hematite ore (A) .In plant sinter, the −1-mm fraction is thought to represent the adhering fines fraction which melts and reacts with the fluxes to form the solid sinter matrix whilst the coarse ...
