Abstract

The purpose of this study is to recycle metals and plastics from waste printed circuit boards with physical separation methods. Recycling is reuse of materials that are recovered from wastes by using physical and/or chemical processes. Computer mainboards is used in this study as one of the printed circuit boards. Physical separation methods are used in recycling process. Computer mainboards are first crushed with crusher for plastics then gravity, magnetic and electrostatic separation methods are applied. Results of magnetic and electrostatic separation tests are not satisfactory. Air jig is used for gravity separation. As a result of gravity separation a concentrate with metal content of % 57,4 is recovered with %86,4 efficiency.
