Abstract

The invention discloses a recycling method of waste electronic products. The method comprises the following steps that the waste electronic products are crushed in a unified manner, and the crushed products are classified; the classified metal products are placed into a sulfuric acid solution to be dissolved and soaked for a period of time; filtering is carried out, metal sediment is flushed withpure water and placed into chloroazotic acid to be soaked for 12 hours, and heavy metal sediment is obtained; and filtering is carried out again, filter residue is taken, the filtered filter residue is smelted and purified, and heavy metal is obtained. Compared with the prior art, the recycling method of the waste electronic products has the following advantages that the method is a metal extraction method of the waste electronic products, the method is simple and rapid, precious metal in waste electronic product chips can be effectively extracted, therefore the recycling and utilizing rate ofthe electronic products is increased, and the method has value of application and popularization.

Description

technical field [0001] The invention relates to the technical field of energy recycling, in particular to a method for recycling waste electronic products.
