Dry coal preparation without the use of water STEINERT

This offers a wide range of applications for the coal. With this method, the de centralised pre concentration of coal in small, remote mines allows the coal to be separated from the waste rock, to immense economic advantage. Transport costs are massively reduced, or the coal is sold directly as a high quality product.

TENORM Bauxite and Alumina Production Wastes US EPA

The refinery processes used to produce aluminum generates about 2 2.5 tons of solid waste for every 1 ton of aluminum produced. This includes a small amount of waste rock, waste muds and a small amount of other scrap and solid wastes. These wastes can contain TENORM.

Iron Ore Mining Artifacts

The grain size of the magnetite and its degree of comingling with the silica groundmass determine the grind size to which the rock must be reduced to enable efficient magnetic separation to provide a high purity magnetite concentrate. This determines the energy inputs required to run a milling operation.

What Type of Rock Is Magnetic? Reference

The magnetic mineral magnetite is commonly found in igneous rocks. The mineral magnetite that occurs in a variety of geologic environments is one of the few elements that cause a rock to become magnetic. This mineral is one of the most widespread iron oxide minerals. Magnetite is usually dispersed through a rock as microscopic crystals.

Homepage QMAG

Magnetite is a mineral and one of three common naturally occurring oxides of iron. Its chemical formula is Fe 3 O 4 and it is a member of the spinel group. Magnetite 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
