Enhancement of Magnetic Properties of Malaysian

The magnetic properties of iron ores were improved at 700 and 800°C, but the presence of wustite lowers the magnetic properties compared to 600°C. Increasing temperature up to 900°C enhances the magnetic properties of iron ore due to the presence of magnetite and metallic iron which are classified as strong magnetic materials.

Iron Ore - AIMR 2011 - Australian Mines Atlas

Iron (Fe) is a metallic element which constitutes about 5% of the Earth’s crust and is the fourth most abundant element in the crust. Iron ores are rocks from which metallic iron can be economically extracted. The principal iron ores are hematite (Fe 2 O 3) and magnetite (Fe 3 O 4).. Hematite is an iron oxide mineral. It is non-magnetic and has colour variations ranging from steel silver to ...

Magnetic particles for the separation and purification

2006-10-25  In the laboratory, colloidal magnetite Fe 3 O 4 (or similar magnetic material such as maghemite γFe 2 O 3 or ferrites) particles usually are surface-modified by silanisation. Naked iron oxide (Fe 3 O 4) has the capacity of adsorbing DNA (Davies et al. 1998), but aggregates due to attractive forces reduce the surface area that can be used for adsorption.Silane compounds coupled to

For the extraction of metallic iron, the compounds formed between iron and oxygen, so-called oxides, play a wholly dominant role. The iron ore mineral is called magnetite (black ore) or hematite (bloodstone ore), depending on the type of oxide of which it is composed. Magnetite has acquired its name through its magnetic properties.

2017-4-12  Iron mining and ore milling. At the time, the iron and steel industries were the largest in the world. But in the eastern United States, where Edison worked and lived, the best iron deposits had already been mined. Furthermore, new steel-making technologies demanded very pure iron ore, purer than the remaining eastern iron deposits could offer.

Chemistry for Kids: Elements - Iron

Iron is the most naturally magnetic of the elements. Other naturally magnetic elements include cobalt and nickel. Iron becomes significantly harder when alloyed with other elements such as carbon. Iron can be found in four allotropic forms. The most stable form of iron at normal temperatures is alpha iron which is commonly known as ferrite.
