Dissolution kinetics of celestite (SrSO4) in HCl solution with BaCl2 .Jan 11, 2018 . The activation energy for the leaching process in 8.25 × 10− 3 M BaCl2 solution equilibrated with 0.5 M HCl was found as 68.8 kJ mol− 1. This value reveals that the dissolution of celestite is a chemical reaction controlled process. In agreement with the model, the reaction rate is inversely proportional to the.celestite milling process,Fracture filled with celestite (C1) and recrystallized calcite (Ca2).The objective of this process was to achieve preconcentration of celestite by differential grinding from the softer carbonate impurities. A ''Denver D12'' flotation conditioner with a single axis, three bladed double- propeller was used for such purposes. Attritioned products were classified on 0.25 mm screen and both over- and.
