Wet beneficiation/coal washing. Currently, the wet coal beneficiation process is the predominant method for coal upgrading. The wet beneficiation processes include heavy media separation, cyclone (water only), froth flotation, and spiral separation [23,24]. The use of these technologies depends on the particle size of the feed and the ...

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 "heavymedia" process using magnetite is standard for coarse coal cleaning.

Effective processing and use of coal slime is of great significance to protect the environment and save resources. Different coal slimes (untreated with 43 wt% ash content, crushed and flotation treated with 10 wt% ash content, and precarbonized) were activated with KOH to prepare porous activated carbon. The results show the activated carbon prepared from coal slime with 10 wt% ash had high ...

As finer sizes of coal are washed, new techniques will be used. In the accompanying flow sheet for the Homer City coalwashing plant of the Penelec Co. shown as Fig. 6, there is a heavymedium cyclone which receives the underflow of a 2 mm x 0 classifying cyclone which makes a split at 100 mesh. Thus, the cyclone input is sized at 2mm x 100 mesh.
