Waste copper recycling process

Abstract

The invention discloses a metal recycling and refining process, and particularly relates to a waste copper recycling process. The technical scheme comprises the following steps that firstly, the recycled waste copper is preprocessed, oxides, dirt and organic compounds on the surface of a waste copper product are removed, and the waste copper is pre-treated before the waste copper is smelted, and the dirt, the dirty oil and the organic compounds are removed on the surface of the waste copper product; Secondly, smelting is carried out at high temperature, so that anode copper is manufactured; and thirdly, electrolytic refining is carried out, the anode copper is separated out of the cathode copper plate by means of electrolysis, so that pure copper is obtained. The method is complete in process and good in recycling effect.

Description

technical field [0001] The invention relates to the technical field of metal smelting, in particular to a waste copper recycling process. Background technique [0002] With the rapid development of the national economy, on the one hand, copper consumption has grown rapidly and copper prices have soared, while my country's copper resources are in short supply, and the output of copper concentrates is difficult to meet the demand; on the other hand, waste household appliances and waste cables have also increased rapidly in recent years, causing environmental pollution. Therefore, the recycling of scrap copper is a shortcut for the rapid development of my country's copper industry to make up for the shortage of raw materials. [0003] In daily life and industrial manufacturing, a lot of scrap copper is often produced, such as: discarded red copper wire, brass in the socket, bronze and white copper on the door frame, etc., its composition is relatively complex, in addition to co...

AI Technical Summary

Problems solved by technology

Because it is difficult to deal with this kind of scrap copper, at present most of these scrap copper are processed in a simple way and then sold out, which will not only cause certain pollution to the environment, but also make the comprehensive utilization efficiency of the resources in the scrap copper not high. Lead to the loss of valuable components such as metal copper

In order to recycle the valuable metals of waste copper scraps, in the past, some manufacturers used technologies such as iron removal and calcination to process waste copper scraps and sell them as raw materials. Although the process is simple, the pollution is serious, and the purpose of comprehensive resource recycling cannot be achieved. Because there are more oil stains and organic compounds on the surface of scrap copper products, a large amount of harmful gas is produced during scrap copper smelting, which endangers the health of workers and pollutes the environment.
