Magnetite ore (Fe3O4) is a ferromagnetic mineral commonly used in magnetic separation coal washing processes.. Coal washing using magnetite is used to remove contamination from run-of-mine (ROM) coal, which usually contains rocks, middlings, used consumables and other contamination introduced by the mining process.
Martin and Robson is the preferred supplier of dense media separation (DMS) magnetite, used for coal washing, to global mining companies.. Martin and Robson's customer base includes big mining groups as well as small independent coal washing companies. Martin and Robson also has a specialised magnetite milling plant in South Africa able to mill DMS ore to customer specification.
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.

Martin and Robson: Magnetite Ore Supply and Processing Martin and Robson is a world leader in the supply and processing of DMS magnetite ore and other minerals to various industries. We are renowned in the mining industry for our consistency as a high quality magnetite supplier to coal separation processing and coal washing customers.
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.
Magnetite's use in coal washing stems from its ability to be mixed in suspension to produce a separating medium of a precise specific gravity, the low viscosity of these mediums and the ease of recovery for recycling purposes are what makes magnetite such a useful material. Dense medium processing, using finely milled magnetite ore is one of ...
1. For "Loss through product" please take samples of the clean coal, reject and middling for laboratory test by thorough washing and determine the .magnetite content. Repeat the test after suitably changing the settings of the rinsing screen, such as spray water rate, screen vibration etc. 2.
the coal and the noncombustible material (ash) are in the raw coal. Pure coal has a specific gravity in the range of 1.23 to 1.72.1 Pure ash is heavier, with a specific gravity of more than 2.3.
