Introduction. Hot gas filtration has been attracting more and more attention in a wide variety of processes over the last years. Main reasons for that are higher demands on emission levels, such as PM 10 and PMthe possibility to simplify or to intensify processes, problems to supply and to clean wash waters for wet scrubbing as well as the development and application of new processes The Bureau of Mines conducted laboratory beneficiation tests on four samples of waste granite sludge to devise a method of recovering silicon carbide (sic).
