US3737032A - Coal preparation process and magnetite

View More

A coal preparation process includes a dense medium coal separator which utilizes a magnetite media for separating raw coal from refuse. A sieve receives coal from the separator and is utilized to drain a portion of the magnetite media from the coal before the coal is passed into a new magnetite reclaimer wherein paddles agitate the coal causing abrasive contact between the coal particles to

The first uses a natural medium (water and raw material) and secondly a dense medium (with magnetite added). Natural Medium Washing Plant The natural medium washing plant is the most cost-effective coal preparation method of processing easily separated coals, in particular run of mine coal

Heavy-media Cyclones for coal cleaning | FLSmidth

View More

Like the heavy-media vessels, Heavy-media Cyclones also are designed to clean coal and minerals based on their density differences. Using finely ground magnetite and water as the media to create a buoyancy effect for gravimetric separation, the Heavy-media Cyclone forces the lighter solids to its centre, where the slurry transports them upward and through the vortex finder

Aug 06, 2019 In South Africa, coal is predominantly processed through a wet “float and sink” beneficiation process that uses a water-based slurry of magnetite. This extremely water-intensive process not only places the country’s limited water resources under pressure but also has the potential to pollute to the environment, particularly groundwater

The first washing methods were imported from Europe, The “Chance” washer, in which the density differences between coal and mineral matter was exploited to clean raw coal was introduced in 1918. The Chance washer utilized sand and water as a medium. Today, the “heavy-media” process using magnetite is standard for coarse coal cleaning

In heavy-media separations, the specific gravity of the medium used for separation, usually a suspension of finely divided magnetite in water, is chosen to achieve a given degree of separation depending on the characteristics of the coal, the desired product quality, and the acceptable level of coal loss to the rejects. In water-only devices such as jigs, spirals, and water-only cyclones, separation is effected by the differential acceleration of coal
