Embodiment 1

[0044]The method for recovering gold by using the above-mentioned equipment for recycling gold from electronic wastes comprises the following steps:

[0045] (1) Put the electronic waste into the crushing mechanism, and the crushed electronic waste is obtained after crushing; the particle size of the crushed electronic waste is controlled within a certain range (determined according to the aperture of the screening plate).

[0046] (2) Add the pulverized electronic waste of step (1) into the stirring mechanism, under the agitation of the stirring paddle of the stirring mechanism, add the prepared gold removal solution, the gold removal solution can dissolve the gold of the pulverized electronic waste, and filter to remove Gold solution (containing gold ions); the pulverized electronic waste whose particle size is controlled within a certain range is degolded by the degolding solution, and the effect of the degolding treatment is better and the efficiency is higher. Wherein, th...

Abstract

The invention belongs to the technical field of gold recovery, and discloses equipment for recycling gold by recycling electronic wastes. The equipment for recycling gold by recycling the electronic wastes comprises a crushing mechanism, a stirring mechanism and a filtering mechanism. The crushing mechanism comprises a shell, a feeding screw, two crushing rollers, a screening plate, a material pushing screw, a longitudinal baffle, a lifting screw and a first wedge-shaped block, wherein a feeding cylinder is longitudinally arranged in the shell, the feeding screw is longitudinally arranged at the upper end of the shell, the two crushing rollers are driven by a speed reducer to rotate oppositely, the screening plate is arranged in the shell and located below the two crushing rollers, the material pushing screw is used for pushing materials on the screening plate, the longitudinal baffle is longitudinally arranged in the shell, and the lifting screw is used for lifting the materials discharged from a first discharge port. The invention further discloses a method for recycling gold by recycling the electronic wastes, which can ensure that the particle diameter of the crushed electronicwastes collected by a second discharge port is controlled within a certain range, and the range is determined according to the hold diameter of the screening plate, so that the efficiency of gold separation treatment of the crushed electronic wastes in the stirring mechanism is improved.

Description

technical field [0001] The invention belongs to the technical field of gold recycling, and in particular relates to a device and a method for recycling gold by recycling electronic waste. Background technique [0002] With the rapid development of society, the replacement speed of electronic products is gradually accelerating, which brings a large number of waste electronic components, gold-plated waste circuit boards, and unqualified gold-plated parts in electroplating factories. To reduce the waste of resources, the reuse of gold on the surface of gold-plated parts has become very necessary. [0003] In the current process of recycling gold from electronic waste, the electronic waste that has not been pulverized is usually directly put into the gold return solution for treatment, which affects the efficiency of gold return treatment. [0004] In order to solve the above problems, the present invention proposes a device and method for recycling gold from electronic waste. ...
