Research conducted at Southern Illinois University at Carbondale over the past two years has identified highly efficient methods for treating fine coal (i.e., -28 mesh). In this study, a circuit comprised of the three advanced fine coal cleaning technologies is being tested in an operating preparation plant to evaluate circuit performance and to compare the performance with the current technologies used to treat -16 mesh fine coal. The circuit integrated a Floatex hydrosizer, a Falcon concentrator and a Jameson froth flotation cell. The Floatex hydrosizer is being used as a primary cleaner for the nominally -16 mesh Illinois No. 5 fine coal circuit feed. The overflow of the Floatex is screened at 48 mesh using a Sizetec vibratory screen to produce a clean coal product from the screen overflow. The screen overflow is further treated by the Falcon and Jameson Cell. During this reporting period, tests were initiated on the fine coal circuit installed at the Kerr-McGee Galatia preparation plant. The circuit was found to reduce both the ash content and the pyritic sulfur content. Additional in-plant circuitry tests are ongoing.
