Planning for coal beneficiation in the electric utility industry is relatively complex, involving the coordination of experts and specialists in a broad range of fields, as well as compliance with a wide variety of government regulations. This paper examines the role of the planner, reviews possible benefits of coal beneficiation, identifies potential problems and illustrates a typical planning schedule. The steps involved in the planning process are: Step 1—Bench- and pilot-washability study Step 2— Wash plant design Step 3—Power plant and boiler design Step 4—Mine design Step 5—Major environmental and technical problems to address.
