Magnetite
Magnetite is a rock mineral and one of the main iron ores, with the stone formula Fe₃O₄. It is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself. It is the most magnetic of all the naturally-occurring minerals on Earth. Naturally-…
Ore Beneficiation - an overview | ScienceDirect Topics
Jan 04, 2007 · Hematite and magnetite are the most prominent iron ores. Most of the high-grade hematite iron ores (direct shipping ore (DSO)) are subjected to simple dry processes of beneficiation to meet size requirements.
Hematite Processing by Flotation
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 mineral as low as 25% Fe can be treated with “Sub-A” Flotation to produce concentrates that average better than 62% Fe with less than 9% SiO2 and with a high recovery.

Beneficiation of High-Aluminium-Content Hematite Ore by Soda Ash Roasting. High-aluminium-content iron ore is one of typical intractable iron ores, and magnetic separation and floatation processes are found impracticable to remove alumina from the ore effectively.
What Is Iron Ore Beneficiation? (with pictures)
Oct 26, 2019 · Iron ore beneficiation is a multi-stage process that raw iron ore undergoes to purify it prior to the process of smelting, which involves melting the ore to remove the metal content. The process of iron ore beneficiation has two complementary goals and these define the methods used to refine it.

Hematite Beneficiation Process Hematite is weak magnetic. It contains mainly Fe2O3, concluding Fe70 %, O 30%, which is the major iron ore. Based on the test report of ore provided by customer, we designed this hematite dressing technics: three stages crushing----one stage milling----two stages magnetic separation---- dehydration----final product.
Iron ore and its beneficiation: - Minerals, Mines, Metals ...
Magnetite is beneficiated by crushing and then separating the magnetite from the gangue minerals with a magnet. This is usually so efficient that lower grade ore can be treated when it is magnetite than a comparable grade of hematite ore, especially when the magnetite is quite coarse.

This process can be applied to hematite, hematite containing high fine granularity with uneven thickness impurities, and hematite with small amount of magnetite ore, gangue mineral containing quartz, kaolin and other more complex. Small plant can simplify the process by replace the flotation process with gravity concentration operations.
Iron ore - Wikipedia
Due to the high density of hematite relative to associated silicate gangue, hematite beneficiation usually involves a combination of beneficiation techniques. One method relies on passing the finely crushed ore over a slurry containing magnetite or other agent such as ferrosilicon which increases its density.
