“…Other metals mostly pass into the non-magnetic fraction. The use of wet magnetic separation can be effective for the enrichment of non-ferrous, noble and rare metals by other enrichment methods in order to reduce the contamination of these concentrates with iron [12][13][14]. In order to extract copper, molybdenum, rhenium, gold, silver, rhenium and other elements from dump tailings, studies were carried out using the flotation method.…”

This article is devoted to the additional extraction of valuable components from the waste tailings of the AMMC copper processing plant. The mineral composition of the waste tailings of the CCP is mainly represented by quartz, feldspars, sericites and, in a subordinate amount, mafic and secondary minerals. Pyrite is the most widespread ore mineral in the waste tailings of the CCP. Chalcopyrite, sphalerite, galena, molybdenite, and iron oxides are also noted. The copper content in the selected spot samples from tailings after chemical analysis averaged 0.139%. A sieve analysis was carried out to determine the granulometric composition of waste tailings, the distribution of valuable components by size classes. On the basis of the obtained results on the study of the material composition, flotation of tailings of the CCP AMMC was carried out with recleaning of the main flotation concentrate. During tailings flotation with one recleaning of the main flotation concentrate, the extraction of copper and molybdenum into the total concentrate is 56.8% and 63.8%, respectively.

“…In these cases, the increased speed of the rock mass will contribute to the growth of the efficiency of blasting. It should be noted that the speed of movement of broken rock mass during short-delayed blasting of several layers is always lower than during simultaneous instantaneous blasting under similar conditions [30][31][32][33][34][35][36][37][38][39][40][41][42].…”

the design of downhole explosive charges with an axial air cavity was developed, which ensures uniform crushing of the rock mass and reduces the specific consumption of explosives. A technique has been developed for modeling the process of destruction of a rock mass by borehole charges with an axial air cavity. It has been established that with an increase in the diameter of the axial cavity, the mass of the charge and the specific consumption of explosives for breaking decrease. However, this decrease occurs only up to a certain limit, after which the volume of the chipped mass decreases and the specific consumption of explosives increases. The most efficient way is to reduce the specific consumption of explosives for breaking when the ratio of cavity diameters and charge diameters is 1.3:5–2.2:5. For other values of the ratio, the specific consumption of explosives increases dramatically.

“…At the Morro do Ouro (Brazil) plant, potassium amyl xanthate was used as a collecting reagent during the processing of 0.6 g/t gold ore, and 4-Methyl-2pentanol (MIBC) was used as a foaming agent (consumption of 30 g/t). A flash-flotation gold concentration of 500-600 g/t was obtained [26].…”

Due to shortages, high costs, and the necessity to import, there arose a need to substitute imported reagents with locally produced ones from Uzbek enterprises. This substitution could decrease the cost of reagent procurement, reduce expenses in copper and gold production, and aid in the development of waste-free manufacturing. The material composition of gold-bearing ores is characterized by their complex nature, low concentration of nonferrous metals, and the fine intermingling of valuable components with their host rocks. In our research, the gold-bearing ore from the Amantaytau deposit was selected as the study subject. Gold is a key component of the ore. The primary ore minerals in the sample are pyrite, arsenopyrite, iron hydroxides, and parasites. The non-metallic portion is mainly composed of quartz, sericite, feldspars (albite, orthoclase), carbonates, chlorites, and kaolinite. There is a consistent presence of carbonaceous matter and graphite. The reliability of the research findings was ensured through well-defined objectives. These results emerged from laboratory and semi-industrial scale studies, comparing technological processes for treating difficult-to-enrich gold ores. These processes involved the use of synthesized reagents from local industrial waste, either directly or through electrochemical activation, and combined beneficiation and metallurgical methods. This approach resulted in a notable increase in gold extraction from the Amantaytau deposit ores, ranging from 0.75 to 1.74%. This finding indicates the potential efficacy of electrochemical treatment in the flotation of gold-bearing ores. The results, validated through comprehensive research, demonstrate the successful achievement of the desired outcomes.
