The performance of a hydroacoustics unit, a hydrocyclone and a spiral concentrator processing fine anthracite was evaluated. Samples from the spiral discharge were collected at 3 different diameters of the inlet (23mm, 32mm, and 35mm). It was examined that lowest ash content of approximately 6.5% was achieved with hydroacoustic treatment and with an spiral inlet size of 32mm. Highest yield with acceptable ash content (7.5%) occurred with hydroacoustics and an inlet size of 35mm. Future work involves a comprehensive experiment design and the application of laboratory results at Jeddo Coal, an anthracite mining company in Pennsylvania.
