โฆ Synopsis
High capacity fine coal cleaning using an enhanced gravity concentrator Honaker, R. Q. Miner. Eng., 1998, 11, (12), 1191-1199. According to recent research, enhanced gravity separators provide the opportunity to effectively clean 1 mm x 37 pm coal. A detailed experimental programme was performed on a continuous Falcon Concentrator, which was found to achieve separation at mass throughput capacity values in excess of 75 ton/h. The apparent particle separation density for 1 mm x 75 pm coal was about 1.60, with relatively high efficiency. Typical ash and sulfur rejection values of 85% and 70%, respectively, were achieved while recovering 85% of the combustible material. Metallurgical and efficiency data from the evaluation are presented.
