Analysis of the possibility of extracting copper from wastewater with low metal concentration by extraction method

The urgency of the problem of industrial wastewater treatment became apparent after assessing the con-sequences of its discharge into water bodies. Non-ferrous metallurgy enterprises are one of the main sources of pollu-tion of surface and groundwater. Today, common methods of wastewater treatment from copper are aimed at protecting the environment. However, their economic efficiency is usually low or non-existent. The solution to the problem may lie in the possibility of obtaining pure copper, a product that is in high demand. Currently, this is possible due to selective extraction at high concentrations of copper in wastewater. However, the issue of extracting copper from solutions with low concentrations in the production of commercial copper remains unre-solved. Thus, wastewater with a low concentration of copper is currently the main source of pollution of water bodies. This article describes the results of an experiment aimed at the selective extraction of copper from low-concentration wastewater using a new extracting.
