Innovative, advanced coal cleaning processes are being developed to address emerging requirements in emissions control, increased recovery of energy resources and cleanup of existing environmental insults. These processes offer novel, cost-effective, pre-combustion approaches to removing substantially greater percentages of Hazardous Air Pollutants (HAPs) from coal than would typically be realized using conventional coal cleaning processes. Of equal importance is the potential that these processes offer in recovery of the estimated 2--3 billion tons of coal fines that currently reside in impoundment areas in the US, as well as the 30--40 million tons of coal fines discarded annually in the US to waste slurry ponds. These processes can be a specific response to the political, social, and economic impediments to siting and operating waste disposal areas. The processes that can minimize the amount of coal fines discarded to waste impoundments and improve the efficiency and economics of carbon recovery when beneficiating fine coal obtained from current production processes will be introduced and their new, environmentally focused role examined. This will include processes to produce carbon-based feedstocks that offer superior performance or economics for the production of liquid transportation fuels and chemicals, as well as reduce HAPs.
