A coal preparation plant (CPP; also known as a coal handling and preparation plant (CHPP), coal handling plant, prep plant, tipple or wash plant) is a facility that washes coal of soil and rock, crushes it into graded sized chunks (sorting), stockpiles grades preparing it for transport to market, and more often than not, also loads coal into rail cars, barges, or ships.
Along- with the discharged water, small particles of coal are carried away to the pond where the coal particles settle down on the surface of the pond, and the same is collected after the pond is de-watered. The coal particles so collect- ed are of fine quality, ash free and the same is used as fuel.

Today, the universal disposal method for tailings is the tailing pond. Tailings are slurried with water and pumped to tailing ponds for settling. Frequently, tailings are cyclone-classified before deposition. Coarse sands are used to build-up the tailing dam, while the slimes are deposited inside the pond.
