Types of Iron Ore: Hematite vs. Magnetite
· The deposit was discovered in 1844, and ore was first mined there in 1848, as per the Michigan government's website. Among the four types of iron ore deposits found in this area are magnetite ore and hematite ore. In Minnesota, magnetite ore is mined mainly in the Mesabi Range, one of the four ranges that make up the Iron Range of Minnesota....

· The magnetite–hematite ores of the Mikhailovskoye deposit are characterized by fine dissemination of ore and gangue minerals, the complexity of the structural and textural features and material composition, a lowlevel contrast in the magnetic properties of the separated minerals, and so forth. 28−30 The content of iron in these ores ranges from to %, the average content of ....
Estimation of Fe in Magnetite | Minalyze
A Swedish iron oxideapatite deposit, explored by Nordic Iron Ore, contains both magnetite and hematite. Drill cores from this project were analysed with Minalyzer CS. Magnetite content has been measured with a Satmagan. Some samples display higher Fe concentrations than can be explained by their magnetism....
Types of Iron Ore: Hematite vs. Magnetite(vs Taconite
· Additionally, its Hibbing taconite mine is in Minnesota's Mesabi Range and has an annual rate capacity of 8 million tons of magnetite ore." "Taconite is a lowgrade iron ore. When the highgrade natural iron ore was plentiful, taconite was considered a waste rock and not used. But as the supply of highgrade natural ore decreased, industry ......
EFFECT OF MAGNETITE, HEMATITE AND PELLET SCREENINGS .
This study compares usage of three LKAB iron ores as an addition to the sinter blend. In this work, concentrates from magnetite and hematite are compared to pellet screenings as raw material in sintering. In order to minimize variations in the production process, the sinter pot at SGA has been used to produce 4 different types of sinter....
Why Haematite iron ore is preferred against magnetite iron ...
· hematite ore generally contains large concentrations of hematite, magnetite ore generally holds low concentrations of magnetite. As a result, this type of iron ore ore must be concentrated before it can be used to produce steel. In other words magnetite ore requires more treatment than hematite ore wich must undergo only a simple crushing ......

Iron oxide coppergold (IOCG) deposits (Hitzman et al., 1992) are a diverse family of mineral deposits characterised by the following features: (1) Cu with or without Au, as economic metals, (2) hydrothermal ore styles and strong structural controls, (3) abundant magnetite and/or hematite, (4) Fe oxides with Fe/Ti greater than those in most igneous rocks, and (5) no clear ....
Why we use hematite over magnetite as iron ore?
Answer (1 of 5): The structure of hematite is hexagonal and that of magnetite is BCT or inverse spinel. During reduction, the phase change in hematite takes place at a temperature of 500 deg C. This change brings with it an increase in the volume thereby increasing the porosity and increased indi......
Difference Between Magnetite and Hematite | Compare the ...
· Magnetite iron is in +2 and +3 oxidation states whereas, in hematite, it is only in +3 oxidation state. This is the key difference between magnetite and hematite. Moreover, magnetite has higher iron content than hematite; therefore, its quality is higher. Apart from that, in colours too, there is a difference between magnetite and hematite....
