碩士 === 國立成功大學 === 資源工程學系 === 84 === Due to the scarcity of metal resources,Taiwan depends on importing basic metals,such as copper,aluminum,zinc and etc.The basic metals are manufactured apliance,motorcycles and cars for internal requirement,and at the same time products a large amount of waste consumer goods which were mainly made of metals. If we can recycle scrap metals,we shall not only gain some useful resources but also solve environment pollution.When magnetic fluid reacts with magnetic field,changing density in magnetic fieldcan cause "heavy" phenomenon on submicro magnetic particles.By this character,thelimit density of separator is wider.Actually,it's suitable way to separate nonmetalsin solid waste at specify gravity about 20.The important point of this research isfinding combined separator and magnetic poles which are consist of high magnetismmeterials for a better magnetic gradient;separating nonferrous,modifying separatorand cycling magnetic fluid are also important.
