An analysis of medium losses in coal washing plants ...

Sep 01, 2006  A simple test procedure was adopted to simulate the drain-and-rinse screen section of the medium recovery circuit in the laboratory. Media with three different relative densities were manually prepared using magnetite (size: 90%, −. 0.045 mm and 90% magnetics) collected from the washery.. The coal had a size range of − 13 +0.5 mm, and 50 g of sample was taken for each test.

Coal preparation plant - Wikipedia

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.

Craigmont Industries Process in Producing Magnetite

The required density of the medium depends on the coal’s properties and is simply adjusted by the amount of high density magnetite used. In the washing process not all the magnetite is recovered, hence, there is a steady demand for good quality magnetite. Magnetite is a form of iron and is mined and sold for that purpose.
