Operators add capacity to process future production By Steve Fiscor, Editor-in-Chief Coal markets softened during the summer of 2023, but activity continues on a steady course for most coal producers. Meanwhile, the medium- and long-term outlook for demand remains strong, especially for metallurgical coal markets. Those trends are …
A coal preparation plant (CPP), also known as a coal handling and preparation plant (CHPP), is a facility that washes coal of soil and rock. The coal handling plant crushes coal into graded sized chunks, stockpiling grades while preparing it for transport to market and, more often than not, loads the coal into rail cars or barges.
