In the past there was often valid economic justification for not processing the ultrafine coal fractions and it was common to simply discard them as tailings. The trend is now to extract as much coal value as possible in the preparation process acros

The majority of coal burned in Indian power stations is high-ash, run-of-mine coal that has been subjected to little or no coal beneficiation to reduce its ash and sulfur content. This article considers each stage of the supply chain of coal from the

Magnetite heavy media processes are accurate, efficient and easy to control separators, capable of producing high quality clean coal. Magnetite recovery circuit operation and magnetite consumption are the main reasons for high capital and operating c
Publisher Summary This chapter discusses the real-time on-line fugitive dust measurement and control. Dust is controlled by adding moisture until the coal no longer generates dust on handling. This occurs at moisture levels higher than the dust extin

Effective beneficiation of fine coal; i.e., coal sized below 1 mm, either by means of deashing or dewatering, or a combination of both, is mainly dependent upon the following factors: (a) favourable coal selling price and a growth situation in coal d

Values are deduced for the contributions to the diurnal range of the horizontal magnetic component by the normal Sq current system and the equatorial electrojet. Both contributions vary much from day to day, but there is only a weak correlation betwe

Measurements have been made on the viscous properties of thixotropic suspensions of titanium dioxide pigments in linseed stand oils. The effects of changes in concentration and temperature have been noted. The viscosity under steady flow conditions c
