Coal preparation is an integral step in the process of mining, preparing, transporting and utilizing coal and should be employed to gain maximum benefits from our coal resource. The desired degree of coal preparation depends on the estimated costs and potential benefits associated with the entire process. Three hypothetical coal preparation plants have been designed to provide a basis for preliminary cost estimates. These are a crushing and screening plant, a Baum jig plant, and a heavy-media plant. In addition, hypothetical facilities for raw coal receiving and breaking, coal stockpiling and blending, prepared coal loadout, and support facilities are included. The design of a preparation plant is based on detailed knowledge of the properties of run-of-mine coal and the feedstock specifications for the conversion plant. Little published data is available for either area to facilitate forecasting the range of future coal preparation plant designs. Based on the estimated capital cost of the hypothetical plants, factors were developed that can be used to estimate the capital costs of plants of differing production capacity. 44 references.
