A comparison study of column flotation technologies for cleaning Illinois coal. Technical report, March 1, 1994--May 31, 1994
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. During the previous reporting period, characterization of an Illinois No. S flotation feed sample was completed and tests on the Jameson Cell were initiated. During this reporting period, parametric studies using a Box-Behnken test design were conducted on the Jameson Cell, Packed-Column, and the Microcel. The results obtained from all three flotation technologies compared well with release analysis data. Excellent ash rejections of more than 85% were achieved by each flotation technology. However, for the test conditions used in this investigation, relatively low combustible recovery values were obtained from the Jameson Cell and the Packed-Column due to carrying capacity limitations. During the next reporting period, lower feed rates will be tested for these two technologies in an effort to improve recovery. Empirical models developed from the parametric studies will be used to predict the optimum operating parameter values. These optimum values will be used to obtain the best possible separation efficiency and maximum throughput for each flotation technology.
