Research on the Recycling of Valuable Metals from Waste Printed Circuit Boards by Eddy Current Separation

摘要：

On the basis of introducing the latest research status of processing methods of waste printed circuit boards,the physical mechanism of eddy current separation was explained,and the component configuration of eddy current separator was described.A series of single-factor and orthogonal experiments were carried out to prove the separation effect of multiple metals with eddy current separator.The result indicates that the separation efficiency of above 92.0％ and concentrate grade of above 95.0％ can be obtained in the recycling of aluminum and brass with the delivery rate of 20～40％,rotate speed of rotor of 5～15Hz and belt speed of 7～9Hz.
