dewatering techniques for fine coal slurry

Coal dewatering technology turns sludge to powder. Because there has been no economically viable technology to remove water from ultrafine coal slurries, the ultrafine particles that are the residue of the coal cleaning process have been discarded into hundreds of impoundments. Now, Peter Bethell of Arch Coal Inc. reports that a dewatering

Fundamentals of Fine Coal Dewatering - ACARP

The objectives of the project were: To develop a reproducible benchmark laboratory vacuum filtration apparatus for characterising the dewatering behaviour of fine coal slurries. To relate microstructural and dewatering properties of fine coal filter cakes. To quantify the extent of interaction of water with black coals and to assess the

Sustainable coal waste disposal practices -

01.01.2019· The first is eliminating slurry impoundments by codisposal of coarse processing waste and dewatered fine processing waste. This practice requires low-cost, efficient dewatering technology for fine waste material, and two contemporary options are discussed. Next, backfilling is explored as an alternative to stowing coal waste in expansive

FINE COAL DEWATERING - vtechworks.lib.vt.edu

FINE COAL DEWATERING Gul Bahar Basim (ABSTRACT) Fine coal constitutes a relatively small portion of a product stream in a coal cleaning plant. However, its processing cost is approximately three times higher than the cost of processing coarse coal. Therefore, many coal companies chose to discard the fines to refuse

Process for dewatering coal slurries (Patent) |

A separation of the slurry into a predominantly relatively fine grain fraction and a relatively coarse grain fraction, with the division point being between about 0.03 and 0.15 mm, is carried out, with a formation of a coal agglomerate from the fine grain fraction, and a dehydration of both the coarse grain fraction and the coal agglomerate from the fine grain fraction.
