Magnetite Concentrate Process

Ernest Henry Mining: Magnetite Processing

Magnetite occurs in nearly all igneous and metamorphic rocks and usually only in small particles or in a solution with other minerals. Some beaches, often called black sand beaches, contain heavy magnetite deposits. John Twomey, Magnetite Project Manager, holds some of the first magnetite concentrate produced at EHM.

Magnetite - Wikipedia

Magnetite is a rock mineral and one of the main iron ores, with the stone formula Fe 3 O 4.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-magnetized pieces of magnetite, called lodestone, will attract …

In great efforts to utilize alternative iron ore resources in sintering process, it was attempted to use magnetite concentrate as an additive in adhering fines of quasi-particle and the effect of ...

Magnetite - an overview | ScienceDirect Topics

Therefore, the effect of adding magnetite concentrates on the pelletizing performance of a Brazilian specularite concentrate was investigated. As shown in Figure 15.13, blending the specularite concentrate with suitable magnetite concentrates has dramatically improved the properties of the green balls. As a result, less bentonite was needed for ...

Sintering of Containing Magnetite Concentrate

magnetite concentrates is very fine, usually less than 1mm.Majority of Chinese steel mills use magnetite concentrate-based ore blends containing various levels of imported sintering fines. Sintering of blends containing magnetite concentrate and various levels of hematite or/and goethite fines then becomesvery important for effective use of the ...

CN105112689A - Method for extracting titanium from ...

The invention discloses a method for extracting titanium from vanadium-titanium magnetite. The method comprises the following steps: adding sodium or potassium salt additive in the reduction smelting of an iron ore concentrate electric stove to obtain liquid iron and titanium-containing slag, wherein vanadium and iron are reduced to enter liquid iron, under a smelting high temperature ...

Global Drivers for High Grade Concentrate | Magnetite Mines

The amount of slag produced during the steelmaking process directly relates to the iron content of the feedstock. Higher iron content equates to less slag. The iron content of direct shipping haematite iron ore is typically 58% to 64%. High grade iron ore concentrate contains 65% to 70% iron. Slag stockpiled alongside a steel mill in China.
