The proposed method makes it possible to increase the degree of copper extraction to an increase of 92.6%. Otherwise, it is possible to take advantage of the secondary extraction method also with a high degree of extraction reaching 90.2%. Further, the invention makes it possible to significantly reduce harmful emissions into the environmental medium. In addition, the invention eliminates the cost of the process as a result of the exclusion of the stage of leaching of ore and of the copper by-product.
