Equipment for recycling gold through chemical electrolysis and using method of equipment

Abstract

The invention discloses equipment for recycling gold through chemical electrolysis. The equipment comprises a tank body, a preheating tank and an electrolytic tank are formed in the tank body through a partition plate, and a plurality of preheating pipes are arranged in the preheating tank; the tank body is connected with a water inlet pipe and a water outlet pipe; the anode plates and the cathode plates are inserted into the electrolytic bath in a staggered manner, and are parallel to the partition plates; steps are arranged on two opposite side walls of the electrolytic bath, and connecting mechanisms for connecting the anode plates and the cathode plates are arranged on the steps; the anode plate is connected with the anode of the power supply main control box through a connecting mechanism, and the cathode plate is connected with the cathode of the power supply main control box through a connecting mechanism; according to the invention, the electrolytic bath is divided into small electrolytic baths by the cathode plates, so that the gold recovery rate of the recovery equipment is greatly improved, and large-scale treatment of an electrolyte containing gold ions is facilitated; the recovery equipment can be applied to a production line of assembly line work and has extremely high generalization performance.

Description

technical field [0001] The invention relates to the technical field of precious metal recovery equipment, in particular to a chemical electrolysis gold recovery equipment and a use method thereof. Background technique [0002] During the mining, smelting, and use of precious metals such as gold, silver, and palladium, a variety of waste liquids containing precious metals will inevitably be produced. Due to the increasing demand and usage of precious metals in modern industry, especially the electronic manufacturing industry, the annual production of waste liquid containing precious metals is also increasing; , are important sources of precious metal-containing waste liquids; because precious metals in waste liquids have extremely high economic value, various research institutions and enterprises are committed to developing processes for extracting precious metals from precious metal-containing waste liquids. [0003] At present, the recovery and extraction methods of precio...

Problems solved by technology

[0004] The use of electrolysis for gold recovery will inevitably use an electrolytic cell. At present, the traditional electrolytic cell usually introduces the waste liquid into the electrolytic cell through the liquid inlet pipe. Although this design is simple in structure, it is prone to the concentration of gold ions in the waste liquid. The problem of inhomogeneity, when the gold is deposited, the deposition thickness on the plate is uneven, which affects the electrolysis effect; the recovery device needs to be shut down to replace the cathode plate and the anode plate, and because there is only a single tank, it is greatly improved. Affect its electrolytic efficiency
