Coal Beneficiation an overview ScienceDirect Topics

Joan S. Esterle, in Applied Coal Petrology, 2008 3.7.2 Mineral and Trace Element Partitioning. As noted, one of the fundamental reasons for coal beneficiation is the reduction of ash yield and deleterious minerals and elements with an inorganic affinity.

INNOVATIVE GRAVITY-BASED TECHNOLOGIES AND CIRCUITS

ultrafine clean coal product from a gravity-based system, the high clay slimes must be removed. Unfortunately, the slimes tend to report with the water in classification systems. When water recovery is restricted, density effects results in the loss of coal to the slime stream. Screening is typically limited by a low open area and blinding.

The Phola coal beneficiation plant is situated in an environmentally sensitive area, the presence of a slimes dam was prohibited. This meant that slimes had to be filtered, but with the benefit that they can be added directly to the Eskom product if the filter cake quality was sufficient.

Collecting behaviors of high internal phase (HIP) emulsion

ABSTRACT In order to tackle the problems of high oily collector consumption and low separation efficiency associated with ultrafine coal slimes, a new collector named high internal phase (HIP) emulsion was prepared. The flotation results showed that the HIP emulsion could significantly reduce the oil consumption by 90% compared with kerosene.
