摘要：

The applicability of carbon dioxide pressure leaching for the production of high purity magnesium oxide from low grade dolomite deposits from different localities in Egypt was investigated. More than 90% of magnesium can be extracted from dolomite ores (Khaboba and Giran El-Foul) under the following conditions: calcination temperature 750 degrees C, leaching temperature 40 degrees C, carbon dioxide pressure 600 kPa and leaching time 120 min. The kinetics of the carbonation process and physico-chemical characteristics of magnesium oxide product were also investigated.
