Removal of selected hazardous air pollutant precursors by dry magnetic separation

Conference ·
OSTI ID:20034324
Most trace elements in coal are associated with minerals that are removed by the MagMill{trademark} (patent pending). In previous measurements, the authors found significant reductions of major trace elements (mercury, arsenic, selenium, and many others) by dry magnetic separation alone. In recent but separate measurements using a 300 Lb/Hr beta prototype MagMill{trademark}, concentrations of trace elements including mercury, arsenic, selenium, beryllium, cadmium, chromium, cobalt, copper, lead, manganese, molybdenum, nickel, thallium, vanadium, and zinc were reduced in the clean coal product and concentrated in the mineral rich fraction removed from the coal. In this paper, the authors report measurements and reductions of sulfur, mineral matter, and trace elements for three US coals--a western Adaville-series coal, an eastern Upper Kittanning coal, and an eastern Pittsburgh seam coal.
