minerals, apatite and dolomite have similar surface properties. Additionally, dissolved components from apatite and dolomite will hydrolyze, precipitate, and adsorb onto the minerals [13–15]. All of these factors determine the interfacial properties of the minerals and make it more difficult to separate apatite from dolomite.

INTRODUCTION Today magnesium is produced industrially either from dolomite ores by thermal reduction of magnesium oxide [1-3] using reactive metals (such as aluminum, silicon or their alloys) as a reductant [4-14] or from magnesium chlo-ride by an electrolytic process [15-18]. The recovery of the magnesium from dolomite ores by

The examined dolomite is composed of 98% of mineral dolomite and 2% of calcite. Other silicates (i.e. quartz) exist only in trace amounts. This dolomite presents intense orange luminescence colour, indicating the absence of impurities and thus high purity. Its chemical composition is: CaO=32.9%, MgO=20.2%, CO2=46.7%, others=0.14% and its isotopic composition is δ18O=−3.10‰ and …

In contrast, dolomite surfaces showed positive zeta potential in deionised water and diluted brines, except for diluted seawater containing added SO2 4 ions. It was concluded that diluted seawater is less efficient in altering the surface charge of dolomite surfaces, due to the tendency of stearic acid to adsorb more strongly on dolomite surfaces.
