【Abstract】 After the floatation test of the slurry with surfactants, a surfactant which could selectively depress coal was obtained. Researches on the changes of Zeta potential on the surface of coal and fossil resin particles before and after the surfactant treatments can explained the cause of coal depressing by surfactants.更多还原
