Smelting plant waste tailing treatment technology and equipment

Abstract

The invention relates to a smelting plant waste tailing treatment technology and further relates to equipment used for achieving the smelting plant waste tailing treatment technology. The equipment comprises a plurality of electrolytic bath boxes which are arranged in a ladder shape. The interior of each box is partitioned through two partition plates arranged in a spaced mode, wherein through holes are formed in the partition plates correspondingly, filter nets are embedded in the through holes correspondingly, two anode plates are located between the two partition plates, anode grooves are formed between the anode plates and the corresponding partition plates correspondingly, two cathode plates are located on the outer sides of the partition plates correspondingly, cathode grooves are formed between the cathode plates and the corresponding partition plates, and an electric mixer is arranged between the two anode plates. A conveying pipe group used for conveying an electrolysis mixture is fixedly connected between every two boxes. By applying the electrolysis equipment and the corresponding electrolysis technology provided by the invention, the hazardous tailing treatment cost canbe lowered for enterprises, in addition, electric chlorination continuous production is achieved while the substance gold is obtained, and the treatment technology and equipment can be widely appliedto the technical field of electrolysis technologies and electrolysis equipment.

Description

technical field [0001] The present invention relates to the technical field of waste tailings treatment in smelters, specifically to a treatment process for waste tailings in smelters; the invention also relates to the technical field of chemical electrolysis equipment, specifically to equipment for the treatment process of waste tailings in smelters . Background technique [0002] The technology of extracting gold and silver by electrochlorination was introduced in detail in the "Handbook of Gold and Silver Production and Processing Technology" edited by Li Peizheng in 2003. However, this technology is still in the research and experimental stage, and has not been investigated. To the report that has put into production example, also do not see the application example of smelter adopting electrochlorination method to extract gold and silver in waste tailings. On the other hand, the discarded slag containing sodium cyanide and high alkali value used to be directly discharge...

AI Technical Summary

Problems solved by technology

[0003] The gold and silver in the waste tailings of smelters have high economic value. In the prior art, the tailings are not fully utilized, but are discarded as waste, which wastes resources; the existing electrochlorination technology only stays at the research level. , In the experimental stage, it has not been applied to actual production, and the existing environmental protection treatment costs for cyanide and high alkali value in the waste tailings of smelters are relatively high, and the operating costs of enterprises are relatively high

The electric chlorination mixing tank used in the prior art is a single mixing tank with small processing capacity and high cost, and the diaphragm layer of this circular tank is not easy to fix, clean and replace, and it is not easy to install a ventilation device. It is not easy to realize the series connection between the mixing tanks

In actual treatment, due to the slow stirring speed of electrochlorination, the material in the circular barrel is easy to form sediment
