The Task 6 effort involves three main elements including column cell development, flotation circuit testing and flotation cell modeling. The work outlined is to research column designs and operation parameters in developing an optimized column flotation cell (OCFC) to meet the overall program objectives. The test results obtained through this effort will be evaluated against the results obtained from the round-robin test program in Task 5. Any design parameters or operating conditions that are unique with the round-robin test winner that were not evaluated as part of the optimized column developments work will be reviewed and tested so as to incorporate all possible scenarios in presenting DOE with the best available flotation process for use in the 2 to 3 ton per hour POC. Following development of the OCFC, various flotation circuit configurations will be evaluated determine the best'' circuit design for the 2 to 3 ton per hour POC. Single and multiple stage flotation, grab and run,rougher/scavenger/cleaner, etc., test circuits will be tested as part of this effort. Upon completion of this test work, the best'' possible flotation cell will have been tested in a number of possible flotation circuit designs to possibly provide the best'' flotation approach in meeting the design criteria. In conjunction with the flotation test effort, model development work will be conducted to provide a tool in evaluating the various flotation circuit configurations and in predicting flotation performance. The model will be useful in selecting operating conditions in the POC and in evaluating the performance of the POC.
