提供了一种利用有机溶液从废弃的印刷电路板中回收金属的方法，通过使用有机溶剂对废弃的印刷电路板进行预处理，提高了金属的回收率。将切割后的废弃印刷电路板放入有机溶剂中。所述有机溶剂为N，N-二甲基甲酰胺、甲乙酮、四氢呋喃、Stripoxy或其混合物。金属和塑料是通过混合废弃的印刷电路板来选择的。用筛子从有机溶液中分离出金属和塑料。将分离出的金属和塑料混合物洗净并烘干。
A method for collecting metal from the wasted printed circuit board using the organic solution is provided to raise the recovery rate of metal by pretreating the wasted printed circuit board using the organic solvent. The cut wasted printed circuit board is put into in the organic solvent. The organic solvent is the N, N-Dimethylformamide, the methyl ethyl ketone, Tetrahydrofuran, Stripoxy or their mixture. The metal and plastic are selected by mixing the wasted printed circuit board. The separated metal and plastic are separated from the organic solution by using sieve. The separated metal and plastic mixture are washed and dried.
