Dewatering screen, the main function is dehydration, desludge, demedium, can be used for sand washing in sand and gravel plant, coal slurry recovery in coal preparation plant, dry discharge of tailings in mineral processing plant, etc., so it is also called sand and stone dewatering sieve, mining dewatering sieve, slime dewatering screen, tailings dewatering screen, etc.
Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore. Tailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed.
D. Woodruff, L. Macnamara, in The Coal Handbook: Towards Cleaner Production: Coal Production, 2013. Tailings ponds (open circuit). If sufficient area is available close to the plant, by far the cheapest solution to tailings disposal is to pump the tailings from the thickener underflow to a pond or lagoon, where the solids can, over time, settle out to a dense saturated solid bed and the ...
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.
Coal Cleaning Process Description12,9 Coal cleaning is a process by which impurities such as sulfur, ash, and rock are removed from coal to upgrade its value. Coal cleaning processes are categorized as either physical cleaning or chemical cleaning. Physical coal cleaning processes, the mechanical separation of coal from its

The Macquarie Coal Preparation Plant prepared coal from the West Wallsend Colliery in the Newcastle coal fields. Before coal washing stopped at the plant, the company needed to cap its tailings storage facility while it also continued to operate. The challenge was how to progressively cap a facility that was still receiving tailing deposits.
