Natural dolomite was calcined at 700–900 °C under air and an Ar gas flow atmosphere to characterize its sorbency potential for borate.A sequential decarbonation occurred with increase in calcination temperature, that is, transformation of CaMg(CO 3) 2 to MgO and CaCO 3 up to 700 °C and CaCO 3 to CaO from 700 to 900 °C. The surface …

Calcite also forms flat, rhomboid "poker chip" crystals, but dolomite does not. Calcite responds vigorously to acid, while dolomite responds less vigorously. Calcite is 3 on the Mohs Scale of Hardness, but dolomite is only Mohs 4-4.5. One other difference you may see is the smoothness of the crystal faces on your specimen.
