During this past quarter the performance comparison between the microbubble column and conventional flotation cells (Task 1.2.5 -- Coarse Coal Flotation) continued using minus-28-mesh Upper Freeport seam coal. For an equivalent recovery, the microbubble column reduced the final ash content of the product by more than 50% of that obtained for conventional flotation. It was found that the 14-inch microbubble column could produce a 10% ash product with combustible recoveries greater than 90%, as compared to a 20% ash conventional flotation product. 2 figs., 1 tab.
