Almatov Ilhomjon Mirzabek Ogli | Sagdiyeva Muyassar Gaybullayevna | Yusupkhodzhaev Asad Makhamatovich "Extraction of Valuable Elements from Ash of Fuel Shale of the Aktau and Sangruntau Deposit" Published in International Journal of Trend in Scientific Research and Development (ijtsrd), ISSN: 2456-6470, Volume-4 | Issue-5, August 2020, pp.1139-1142, URL: https://www.ijtsrd.com/papers/ijtsrd33064.pdf

Hydrometallurgical methods are aimed at leaching for the extraction of valuable components into a sulfuric acid solution, as well as selective extraction on ion-exchange resins by the method of sorption and precipitation of valuable components such as vanadium oxide, molybdenum oxide, zinc oxide and the amount of REE oxide and uranium oxide. The presented methods are not implemented on an industrial scale, since there is no processing of oil shale in the Republic. A prospective scheme for processing ash from oil shale deposits has been analyzed. It includes the addition of sodium chlorine to the oxidative roasting process, the resulting ash is leached in vats with sulfuric acid 150 g/l, at room temperature, S:L= 1:5, duration 60 minutes. The resulting metal-bearing sulfuric acid solution is filtered and sent to sorption, as well as precipitation. The extraction of metals into solution is,%: vanadium - 84.3 - 85.6, molybdenum - 95.4 - 88.1, zinc - 69.6 - 71.1, uranium - 60.3 - 64.9 and the amount of REE - 66.2 - 49.2, respectively. For the extraction of metals from productive solutions of leaching ash from oil shale deposits of Aktau and Sangruntau, the following ion-exchange resins of the Anglia company PUROLITE were used: for vanadium grade A-109 extraction 79 - 81%, for molybdenum - grade A-100 extraction was more than 84 - 86% , uranium grade A-560 extraction 81 - 79% and for zinc S-984 extraction 75 - 71%. Carried out precipitation to extract REE and received 18% content of the amount of REE.
