During the past year, a joint project between the US Department of Energy (DOE), the Virginia Center for Coal and Minerals Processing (VCCMP) and the Shell Mining Corporation (SMC) was initiated to implement the testing of a full-scale microbubble flotation column. The work is being carried out at the Marrowbone Preparation Plant, located near Naugatuck in southwestern West Virginia. The primary objective of this effort was to determine the feasibility of using microbubble column flotation for the recovery of coal fines from a classifying cyclone overflow stream that is presently being discarded as refuse. During the past quarter, results obtained using a 30-inch diameter test unit were reviewed, flowsheet layouts and preliminary scale-up projections were generated and design, engineering, fabrication and installation of the full-scale test unit was completed. Preliminary results were also obtained with the full-scale test unit and are presented in this report. 5 figs., 7 tabs.
