The report describes a demonstration of the successful recovery of magnetite from mixtures of magnetite and coal, like those found in a coal-washing circuit, by High Gradient Magnetic Separation. The demonstration was part of a research program at Francis Bitter National Magnet Laboratory. High
Magnetite is produced as a by-product of the phosphate mining process of Foskor. At our processing plant in Phalaborwa Idwala Magnetite upgrades this material by magnetic separation and fine milling for supply to the coal industry as a heavy separation medium (for coal washing).
A coal preparation plant (CPP; also known as a coal handling and preparation plant (CHPP), coal handling plant, prep plant, tipple or wash plant) is a facility that washes coal of soil and rock, crushes it into graded sized chunks (sorting), stockpiles grades preparing it for transport to market, and more often than not, also loads coal into rail cars, barges, or ships.
This grade of magnetite is required for washing coal re- duced to 100 mesh and is the grade expected to be used at Homer City. Only one brand of magnetite was used on the advice of Bureau of Mines personnel. The magnetite is mined, crushed, and ball mill ground until the 325 mesh re- quirement is met. It is dried by the supplier.

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 small pieces
for magnetite is in the dense-medium washing process used in most coal preparation plants (Doral Resources NL 1990). This requires a suspension of finely milled magnetite in water. Magnetite is particularly well-suited to this application, because of its high density and recoverability by magnets for recycling (Evans 1993). Magnetite for coal
Depending on the densities of the products that need separating, you can vary the ratio of magnetite and water in the slurry to achieve the required intermediate density. Benefits of using Magnetite in dense medium separation. For many heavy media separation processes, the right slurry density can be reached with Magnetite.
Quality Magnetite : Heavy Media Separation. Magnetite is used in the coal industry as heavy media for coal preparation plants. Separation is achieved by the density and gravity composition of the heavy media coal washing process, please view this page at .mine-engineer .
Coal washing. Coal that comes from a mine is a complex mixture of materials with a large variety of physical properties. In addition to the coal itself, pieces of rock, sand, and various minerals are contained in the mixture. Thus, before coal can be sold to consumers, it must be cleaned.
An analysis of medium losses in coal washing plants. Adhesion to coal and the losses in the magnetic separator are the two main routes through which magnetite gets lost in a coal washing plant. In general, magnetic separators seem to contribute 20–40% of this loss, though this proportion will fall where adhesion losses are abnormally high

Abstract Magnetite losses are generally significant in commercial coal cleaning plants using high-density medium techniques. It is common practice to monitor the cleaned coal, slurries, and refuse using a Davis Tube method in order to isolate and correct unnecessary losses. To ensure the Davis Tube yields correct results, tests were made by comparison with the magnetization determined with a
Magnetite heavy media processes are accurate, efficient and easy to control separators, capable of producing high quality clean coal. Magnetite recovery circuit operation and magnetite consumption are the main reasons for high capital and operating costs.
ISO 8833:1989(en) × ISO 8833:1989(en) In coal preparation, the mineral magnetite (FeO, Fe 2 O 3) has become the most commonly used material, not only because it fulfils all the above criteria, but also because of its worldwide occurrence either as an iron ore or as a by-product of mining operations for other minerals. Like any mineral
