The solid phase concentration of 67–70%

For this reason, the placing of slurry ponds or other type of water impoundment on mine spoil is considered to be a poor practice and is now generally discouraged. An alternative to pond disposal of washing-plant slurries is dewatering of the slurry at the preparation plant and subsequent disposal of the fine refuse with coarse refuse.

To improve the efficiency of the gasification process of coal slurry, it is very important to determine the characteristics of coal–water slurry (CWS) and increase the coal content of CWS. If CWS is produced from low rank coal, the gasification efficiency will be diminished due to the difficulty of generating CWS with high coal content.

The entrained flow gasifier uses coal water slurry (CWS) as a fuel, which is a mixture of pulverized coal, water, and small amounts of surfactants and stabilizers. To improve cold gas efficiency of gasification simultaneously with well atomization of CWS, CWS must have high heating value and low viscosity simultaneously [5] .
