· It comprised several huge grinding mills, magnetic separation units, tailings circuits, pipes going everywhere, and all of this fed by significant water and power resources. Why? Because it was set up to produce magnetite concentrate—a higher grade product which requires an enormous amount of expensive processing and beneficiation.
The mechanism of high pressure roll grinding on improvement of compression strength of oxidized hematite pellets was researched by considering their roasting properties. The results indicate that oxidized hematite pellets require higher preheating temperature and longer preheating time to attain required compression strength of pellets compared with the common magnetite oxidized pellets. It is ...

Processing of Magnetite Iron Ores - Comparing Grinding Options. Although the majority of current steel production is supported by iron ore sourced from high grade haemetite deposits, the long-term growing demand for steel has led to higher raw material prices and opened the way for many new magnetite deposits to also be developed.
Wet drop and dry crush values increased after grinding the magnetite concentrate. However, they were significantly less than hematite pellets at similar bentonite doses. Consequently, particle size effects were not the dominant cause for higher strengths in the hematite concentrate.
Unlike the high-grade hematite ores which are easily processed into saleable iron products, through crushing, grinding or milling, concentration by screening, and/or using hydraulic or magnetic classiﬁcation, magnetite ores require extensive beneﬁciation to produce iron concentrates.

Magnetite is a hematite- and magnetite-related oxide mineral. Formed in the oxidation conditions, hematite deposit is huge and associated with hydrothermal activity or sedimentation. Hematite is a metamorphosed sedimentary iron ore, which is mainly composed of magnetite, hematite, martite, and intergrowth with quartz, chlorite and so on.

Hematite is weak magnetic ore, which can be easier separation by flotation than magnetite. In the old days, hematite was separated by gravity separation, however it was weed out for unreachable capacity. Now Hematite iron ore processing is as follows:
magnetite and hematite grinding mill crushing processing Processing of magnetite iron ores comparing grinding options although the majority of current steel production is supported by iron ore sourced from high grade haemetite deposits, the longterm growing demand for steel has led to higher raw material prices and opened the way for many new magnetite deposits to also be developed

Among them, magnetite-hematite is a common mixed ore, and its beneficiation usually adopts a combined process flow composed of multiple beneficiation methods. Single Magnetite-Hematite The single magnet-hematite is mostly fine-grained; the gangue mineral is mainly quartz, and some of it contains iron silicate.
Marked-ball grinding tests were carried out under different grinding conditions and environments. Three types of balls were used, namely, cast hyper steel, high chrome cast iron and EN-31 (forged), which cover a wide range of chemical composition, microstructure and media hardness.
