Investigation of decomposition of dolomite and ...

Dolomite decomposes into magnesium and calcium oxides during the roasting process and precipitates carbon dioxide. Phosphate minerals do not change during the calcination process. Therefore, after calcination, MgO and CaO are converted into a loose structure and fine particle size hydroxides with the help of water during digestion.

Preparation of high purity magnesium oxide from …

oxide from dolomite is the calcination route. Calcite and magnesite decompose at different temperatures, a stepwise decomposition permits the selective calcination in which magnesite is completely decomposed without decomposing calcite. Magnesium oxide is then separated physically from the calcined dolomite by sieving or air separation.

Use of Calcined Dolomite as Chemical Precipitant in ... - …

Calcination at 750 °C was the preferred option as dolomite was decomposed to MgO and CaCO3 for optimal struvite precipitation. Molar ratios of 1.1–1.6:1–2:2 (Mg:P:N) were employed in the experiments. Very robust ammonium removal was obtained with MgO (57%), dolomite 650 °C and dolomite 750 °C (75%).
