how to produce calcined dolomite
Production of high-purity Mg metal from dolomite through …
In this study, a novel Mg production process for producing high-purity Mg metal from dolomite was developed. When the electrolysis of calcined dolomite was conducted using Cu cathode and C anode in MgF 2 – LiF molten salt at 1083–1173 K by applying an average current of 1.42–1.46 A for 9.50–21.0 h, the current efficiency of 66.4–88.6% was …

Differences between raw, calcined and sintered dolomite or dolomite
Calcined dolomite is produced by applying heat to raw dolomite up to 800ºC in a horizontal furnace. During the calcination process, dolomite loses part of its calcium-magnesium carbonate content and transforms into calcium-magnesium oxide. Calcined dolomite is used in the steel industry as an additive in steelmaking, as well as …

Full Guide To Calcite vs. Dolomite (This is the Difference)
Dolomite is slightly harder than calcite, scoring 3.5- 4 while calcite scores 3 on the hardness scale. If you're unfamiliar, the Mohs scale of hardness determines a stone's hardness by measuring how scratch-resistant it is. According to this scale, a stone can scratch any other mineral with a lower score.
