Modeling of the Thermodynamic Interaction of Beryllium Minerals with Different Opening Agents

Modeling of the thermodynamic interaction of beryllium minerals with different opening agents is performed in order to validate the proposed methods of opening beryllium orr at the Ermakovskoe deposit and the structural design of technological equipment blocks. It is found that when beryllium minerals interact with sulfuric acid and alkali the following stability sequences of the minerals are observed: bertrandite–phenakite–beryl with acid and the reverse sequence with alkali. In the case of alkali, the opening of the composition of the reaction products depends on the alkali consumption.
