Abstract

The conventional circuit fine coal circuit typically incorporates spiral concentrators to treat nominal 1 × 0.15 mm material. A study has been performed to determine the operating parameters values needed to achieve optimum separation performances when extending the lower limit of a conventional spiral concentrator to 75 microns. Based on experimental and empirical data, a feed solids concentration about 18% by weight is required with a feed rate of around 100 lit/min. Under these conditions, the ash content in the 150 x 75 micron size fraction was reduced from 22.4% to values lower than 10% while recovering greater than 90% of the combustibles.
