摘要： A method for separating large-sized film-like plastics, such as polypropylene or polyvinyl chloride, which comprises placing the plastics in a separation tank containing an aqueous liquid medium and introducing gas bubbles into the tank thereby to cause the gas bubbles to adhere to the surface of the plastics. The buoyancy of the gas bubbles causes the plastics to rise to the medium surface. Addition of a flotation agent and/or a wetting agent further promotes the floating of the plastics.
