It is clear that, the theoretical MgO content in pure dolomite mineral is 21.875%, this indicates that, the purity of dolomite ore is about 75.66%. The ore contains a high amount of calcium oxide which causes the problems after solid/liquid separation due to high content of produced calcium sulfate dehydrate. In addition, the ore contains a high amount of carbon dioxide, which causes excessive foams during the acid leaching process and consequently decreases the effective capacity of the reactor. In industry, the process can control by increasing retention time, calcinations

Sulfide and sulfate solid solubility in lime, magnesia

2013-4-6  The sulfate solubil-ity In magnesia saturated with MgSO4 was found to be higher than that in lime saturated with CaSO4. At 1100°C, CaSO4 and CaS form in calcined dolomite at SO2 partial pressures higher than those in pure CaO. From these findings it is estimated that at MgO saturation the ac-tivity coefficient relative to CaO is about 0.8.
