The invention discloses a method for recovering copper in a waste circuit board, and the method comprises the following steps of sending the waste circuit board into a vibration device to be vibrated;performing crushing by a first-stage crusher; performing crushing by a second-stage crusher; performing crushing by a third-stage crusher; sorting waste particles by an airflow sorting machine through using the characteristics of different particle proportions, sorting the high-density copper chips for storage and standby, and sending the mixed particles with low density to a pulse dust collector; pulse dust removal; sorting the mixed particles entering an electrostatic separator by the electrostatic separator through using an electrostatic separation principle, and storing the selected copper chips and resin particles separately. The method for recovering copper in the waste circuit board is cleverly designed. After crushing the waste circuit board for many times, the air flow separationand electrostatic separation are performed successively to separate resin particles from the copper, and then the problem that the existing copper recycling process generates a large amount of wastegas and waste water is avoided, therefore the method is clean and environment-friendly.
