X-ray radiation was generated using a copper tube with a wavelength Cu kλ = 1.5406 Å. DiffracEVA decryption software v.4.2, PDF-2 matching phase search database (2016). The weight ratio of the phases was estimated using the standard equation (1), which is based on the determination of the values of integral intensities and the assessment of their contributions.

“…Irrigation is carried out alter-natively with water and solution, followed by cementation of copper with iron scrap. [1][2][3][4] The ammonization methods (ammonia-ammonium extraction) using leaching solutions of ammonia and ammonium salts in the presence of free oxygen or air are known. First of all, an effective and complete uncovering of raw materials and deep separation of target and by-products occur due to this method.…”

The method of using of concentration plants tailings is proposed for the first time in this study. These tailings contain a number of valuable metals, such as Cu, Fe, Zn, etc. and are a potential raw material for obtaining concentrates of some elements. An electrohydropulse discharge is used to intensify the process of leaching of copper and other metals. Ammonium bifluoride, the most effective of the ammonium salts used in the copper leaching by the ammonization method, was chosen as a reagent. The influence of significant leaching parameters is studied and optimized using probabilistic deterministic planning of experiment. Based on the study findings, the following process conditions were found to be optimal: the mass ratio of S : L (solid : liquid) = 1 : 1; Cu : F = 1 : 6; sulfuric acid concentration - 40 g/l; the experiment duration - 30 min; discharge voltage - 10 kV and the leaching efficiency can be achieved 80-85 %. Comparative features of tailings samples from the Karagaily concentration plant (Republic of Kazakhstan) were studied using X-ray diffraction (XRD), scanning electron microscope (SEM), atomic emission spectral analysis. It was found that the copper minerals contained in the tailings are completely shattered and the copper is maximally transferred to the aqueous phase.

“…Among well-known ranking methods, the analytic hierarchy process (AHP) satisfies the formulated conditions. To apply this method, you should use the Saaty scale, which is already included in the expert assessment of socio-ecological criteria [24,25]. Therefore, it is necessary to convert the evaluation criteria into this scale [26][27][28][29][30][31][32][33][34][35][36], to quantify an economic goal using an incremental step based on formula:…”

This article justifies the need to involve technogenic deposits (off-balance ore and wastes) into the economic circulation of mining enterprises when there is a depletion of natural resources. It could be considered as one of the tools of the circular economy. The authors analyze global trends in the development of copper deposits, global demand for copper, and design recommendations for possible alternative options for the copper production. The authors use the case of Erdenet Mining Corporation SOE based in Mongolia to develop the approach for economic, social, and environmental problem-solving. The millions of mining dumps are proposed to develop as technogenic resources for recycled materials, prolonging profitable activities of the mine. The hierarchy analysis method is used to obtain the optimum order of mining dump development to obtain the desired economic, social, and environmental effect.

“…The exploitation of technogenic deposits makes it possible to maintain the required level of metal production even with a significant decrease in the production of metal ores. It should be noted that industrial wastes are often close in composition and properties to natural raw materials, and in some cases, they have advantage [18]. One such example is copper.…”
