Summary:	Title screen New method for processing of beryllium ores to beryllium oxide was suggested and studied. The method is based on decomposition of bertrandite or phenacite with ammonium chloride, with the subsequent leaching of ammonium tetrafluoroberyllate and precipitation from a beryllium hydroxide solution. The thermodynamic characteristics were calculated and a thermogravimetric analysis of the process was made. The kinetics of beryllium oxide fluorination with ammonium fluoride was experimentally studied. A technological scheme of a closed cycle for processing of beryllium-containing raw materials with ammonium fluoride was suggested. Режим доступа: по договору с организацией-держателем ресурса
