In 1988, the Department of Energy's Pittsburgh Energy Technology Center completed five interlaboratory test programs aimed at comparing emerging advanced physical coal cleaning technologies. These five programs included heavy liquid separation, dry separation, selective agglomeration, novel froth flotation cell design, and new froth flotation reagents. Representative portions of three different bituminous coals were sent to all participating organizations; the coals were ground to the appropriate size for the particular process and beneficiated; and the clean coal and refuse products were returned to PETC for chemical analysis. The goal of the beneficiation process was to achieve as high a Btu recovery as possible with a clean coal ash content of 2%--3%. This paper will present the results of all of the participants involved in the two programs dealing with froth flotation. 3 refs., 4 figs., 8 tabs.
