A comparison study of column flotation technologies for cleaning Illinois coal. Technical report, September 1--November 30, 1993

The objectives of this research project are to optimize the performance of six commercially available column technologies for the treatment of Illinois Basin coal fines and to compare their performance on the basis of the recovery-grade curve and column throughput capacity. A statistically-designed experimental program will be conducted to optimize the critical operating performance values of each flotation column. The operating values suggested by the vendor will be used as the center point of the design. The ultimate recovery-grade curve and-the maximum throughput capacity for each column will be determined by conducting further tests using the optimum operating parameter values. During this reporting period, the flotation columns that were not already present were purchased and received. Installation of all the flotation columns was completed with the exception of the Packed-Column which is presently being mounted. A total of 25 fifty-five gallon drums of Illinois No. 5 flotation feed coal ({minus}100 mesh) was collected at a local preparation plant to be used as the feed for the comparison tests. A complete characterization of this coal sample will be conducted during the next reporting period.
