Abstract: FIELD: hydrometallurgy.  
     SUBSTANCE: invention relates to hydrometallurgy of non-ferrous and precious metals, namely to the extraction of gold and copper by leaching of refractory poor gold ore. Ore preparation is carried out to obtain a mineral mass containing gold and copper. After ore preparation, the initial treatment of the mineral mass is carried out with a sulfuric acid-peroxide solution. The solution is obtained by two-stage treatment of a sulfuric acid solution, at the first stage by saturation with diatomic oxygen, and at the second by electrochemical and photochemical treatments with its reinforcement with sulfuric acid. Secondary treatment is carried out by irrigation of the mineral mass with a mixed solution saturated with diatomic oxygen, consisting of a solution of sodium nitrite, 10 g/l, and a solution of sodium chloride, 20 g/l. After a technological pause, they are cyclically irrigated with a 1 g/l sulfuric acid solution saturated with diatomic oxygen and a chloride-nitrite solution containing, g/l: 3 sodium nitrite and 10 sodium chloride, for leaching copper and hard-to-recover forms of gold. Productive solutions are accumulated in a sedimentation pond. Recycled solutions of the corresponding basic reagent composition are prepared for the next irrigation cycle, while a solution freshly prepared in an electrochemical and photoelectrochemical reactor containing active chlorine in the form of sodium hypochlorite, hypochlorous acid is added to the recycled reinforced chloride solution. With a drop in the concentration of copper in the productive solution, it is maintained for 2-3 days, after which the mineral mass is impregnated with an aqueous solution of sodium nitrite saturated with diatomic oxygen, and maintained for 3-5 days. Cyclic irrigation of the mineral mass with recycled reinforced solutions is continued, starting with sulfuric acid, until the next drop in the concentration of copper in the productive solution. Leaching is completed when the required completeness of extraction of copper and gold from the mineral mass is achieved.  
     EFFECT: method provides increased extraction of copper, encapsulated and dispersed gold.

Abstract: FIELD: pipelines.  
     SUBSTANCE: invention relates to the field of construction, namely to the method for coating the inner surface of the pipeline. To implement the method, in accordance with the initial data, a sleeve in the form of a hollow cylinder (2) is made along the pipeline (1) to be reinforced. The sleeve in the folded position is placed inside the pipeline (1) and with the help of winches, cables (3) are stretched along the route of the restored interval of the pipeline with the preservation of space for transporting water masses due to the presence of a channel (4) formed by the folds of the folded sleeve. Through the intake valves (5) on one side of the sleeve, the air mixture is fed into the sleeve formed by hollow annular compartments (7), due to which the structure is straightened and pressed against the inner surface of the pipeline (1). The valves (9), built into the sealed partitions (8) of the annular compartments, provide a step-by-step filling of the sleeve compartments with the output of the air mixture to the exhaust valves (6). Upon completion of the formation of the air sleeve and its pressing against the inner surface of the pipeline through the existing inlet valves (5) of the sleeve, the solidifying material is pumped, replacing the previously filled air mixture inside the hollow annular compartments (7) and displacing it through the exhaust valves (6) to form a channel for transporting water masses inside the sleeve outside the hollow annular compartments. In the sealed partitions (8) on the side of each compartment, there are couplings (10) designed to bind the aggregate after it has solidified in the hollow annular compartments (7) and serve as reinforcement.
