    摘要: A method for recycling metals from swarf includes steps of removing oil in swarf by means of surfactant having a feature of strong hydrophilicity. The steps involves repeated stirring and washing, separating solid from liquid, and separating oil from water so as to force oil separate from the surface of solid, finishing all the steps in 10–30 minutes. Metals after finished the treatment may have only 1% of oil remained thereon, possible to be reused in metalworking. Oil and washing solution are also reusable after treated, so the method is effective both for treating waste and for recycling resources.
