In-situ leaching of molybdenum and uranium by percarbonate and chloride-hypochlorite solutions

In-situ leaching of molybdenum and uranium is becoming an increasingly common process. The features the material composition ores, leading to a decrease in their filtration properties, were considered. Activation with solutions that have undergone electrophotochemical activation before contact ore mass studied. preparation promotes synthesis clustered water molecules collectivized protons hydroxyl ions, as well active forms oxygen hydrogen. Cell from mature tailings Shakhtaminsk deposit was studied experimentally. After pre-oxidation carbonate solution, model borehole carried out chloride-hypochlorite solution. Molybdenum extraction on resin 85 % 30 days. Experiments percolation ores Uchkuduk Sugraly deposits confirmed potential possibility significant increase by electrophotoactivated percarbonate relative aqueous sodium ammonium carbonate. When without additional oxidizing agent, sample 52 59 (sodium carbonate). use hydrogen peroxide agent made it possible achieve 87-88 into pregnant 21 days pre-oxidation. performed studies confirm processing capability extracting columns leaching.
