Influence of process duration and mineral acids concentration on extraction rate of borosilicate ores

Present article is devoted to influence of process duration and mineral acids concentration on extraction rate of borosilicate ores. The results of studies of influence of process duration and concentration of mineral acids on extraction rate of borosilicate ores of Tajikistan have been considered. The decomposition of initial borosilicate raw material with content of B₂O₃=10.4% and concentrate with content of B₂O₃=17.4% by mineral acids has been studied. The optimal conditions of decomposition of borosilicate ore by hydrochloric, sulfur, and nitric acids have been defined.
