Abstract:Recebido em 27/7/10; aceito em 23/10/10; publicado na web em 26/1/11 FLOTATION OF A QUARTZ-CLAY MIXTURE WITH SURFACTANTS AND SUBSEQUENT PILLARING STUDIES. Clay is often employed as a catalyst, but quartz impurities can decrease the catalytic efficiency. Fine particles of clay can be purified by flotation. We examined the cationic surfactant hexadecyltrimethylammonium bromide (HTAB), the anionic sodium dodecyl sulfate (SDS) and the non-ionic TRITON X-100 for separating the quartz impurities from clay. Using X-r… Show more
