Need Of Magnetite In Steel Industries

The major benefit of fully autogenous grinding is the elimination of steel grinding media costs and the need to discriminate between steel and magnetite in coarse magnetic separation

Investigation Of The Effect Of Magnetite Iron Oxide

Jan 01 2015 In addition to reduced costs this means the coarse magnetic separation ahead of pebble crushing does not need to discriminate between steel and magnetite The magnetic separation step between grinding stages progressively reduces the amount of material to be ground and in many cases improves the abrasive properties of the concentrate.The specified tests should ensure that the properties which make magnetite suitable for coal preparation purpose are simply and adequately tested These properties are moisture content particle size distribution total magnetics content relative density total iron(II) content fundamental magnetic.

The Use Of Hydrogen In The Iron And Steel Industry

Magnetite is a natural iron oxide magnet hence the name giving it a very nice distinguishing characteristic Magnetite is the most magnetic of all the minerals on Earth Magnetite is a member of the spinel group which has the standard formula A(B)2O4 The A and B represent different metal ions that occupy specific sites in the crystal structure.Apr 03 2014 These ores can be directly used in the production of iron and steel All other ores need beneficiation and certain processing before they are used in the production of iron and steel Low grade iron ores cannot be used as such for the production of iron and steel and need to be upgraded to reduce its gangue content and increase its Fe content.
