Traffic. • Airports. • Power plants. • Power generators. • Factories and chemical plants. • Breweries and food processing plants. • Wastewater treatment plants.
A coal preparation 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. The more of this waste material that can be removed from coal, the lower its total ash.
