    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 ...

    Beryllium is an amphoteric metal forming the strongly acidic Be 2 and alkaline BeO 2 2 under different conditions. Beryllium metal, carbonate, hydroxide, phosphate, and acetate dissolve in acids or alkalines. Beryllium also shows a very high affinity for oxygen, which predisposes it to the formation of insoluble phosphates ATSDR 2002.
