Most coal preparation plants must put in place strategies in order to preserve their water supply [2]. Such strategies may lead to variability in the quality of the water supply. This particular site used clarified water from the thickener, which was recycled back into the circuit as well as raw water from tailings dams. Approximately 90% of ...

A preparation plant is being designed to treat 700 ton/hr of ROM coal containing an average of 5% moisture (air-dried basis). A nominal 30 x 0.5 mm fraction comprises 80% of the total ROM feed and will be cleaned using DMC units. The required product grade is 7.5%. The washability analysis of the feed material is provided in the following table.

A process flow diagram for a typical coal cleaning plant is presented in Figure 11.10-1. In the initial preparation phase of coal cleaning, the raw coal is unloaded, stored, conveyed, crushed, and classified by screening into coarse and fine coal fractions. The size fractions are then conveyed to their respective cleaning processes.
