magnetic ore separator still used today
Technical Information | Magnetic Mining
Wet low intensity magnetic separators. This is today by far the most widely used type of magnetic separation. But it can only be used for strongly magnetic minerals, so its primary use is for magnetite and ferrosilicon recovery in dense media circuits. Other applications include iron ore concentration and removal of highly magnetic material prior to high intensity wet magnetic separation.

Iron Ore | HowStuffWorks
Smelting involves heating up ore until the metal becomes spongy and the chemical compounds in the ore begin to break down. Most important, it releases oxygen from the iron ore, which makes up a high percentage of common iron ores. The most primitive facility used to smelt iron is a bloomery. There, a blacksmith burns charcoal with iron ore and ...

High gradient magnetic separation (HGMS) has found even broader use in wastewater treatment and food processing. Batch scale magnetic separations are also relevant in industry, particularly biotechnology where fixed magnetic separators are used to purify complex mixtures for protein isolation, cell separation, drug delivery, and biocatalysis.
Maglev Trains Electromagnets in Daily Life
While Maglev trains with passengers travel much slower, they still can travel twice as fast as their wheeled counterparts. As Maglev trains become more and more efficient, they may rival airplanes for land travel. All Maglev trains rely on the attraction and repulsion of magnetic poles. There are two main systems in use today, the EMS and EDS ...

Magnetite Lodestone | Mineral Photos, Uses, Properties
Use of Magnetite as an Ore of Iron. Most of the iron ore mined today is a banded sedimentary rock known as taconite that contains a mixture of magnetite, hematite, and chert. Once considered a waste material, taconite became an important ore after higher grade deposits were depleted. Today's commercial taconites contain 25 to 30% iron by weight.
