Title: In-plant testing of microbubble column flotation

Abstract

Testing of micro-bubble column flotation continued. Work during this time frame was concentrated on completion of the automated control and data acquisition system and the factorial test plan for evaluating the performance of the 8-foot column (Tasks 2.5 and 3.3). Preliminary results obtained from the factorial test program indicate that higher frother addition and aeration rates result in a higher separation efficiency. Furthermore, an increase in collector dosage results in higher column yields under most conditions. The Allen-Bradley PLC has been installed and program development completed for control of the 8-foot column. A completely automated start-up and shut-down sequence has been developed. This sequence can be initiated by the operator from a plant floor industrial interface. Instrumentation of the 30-inch column has also been completed. Testing of this instrumentation is currently underway. 11 figs., 5 tabs.
