METHODS OF PREPARATION OF MAGNESIUM ORGANIC

2003-11-17  A simple method of preparation of organic magnesium compounds (citrate, acetate and aspartate) from natural dolomite with simple apparatus was worked out. In the first stage dolomite was converted into magnesium sulfate and then into basic magnesium carbonate by combination with citric and acetic acids. However, magnesium aspartate was prepared by converting magnesium sulfate into hydroxide and then combining it with aspartic acid. The contents of trace element were determined in the final preparations with ASA. Thermal decompositions of the obtained compounds was studied by means of the thermal analysis. Results could be useful in elaborating method of production of these magnesium compounds from domestic dolomite.

Preparation of high purity magnesium oxide from

2009-8-9  Magnesium oxide suitable for the use in basic refractories was prepared from dolomite (CaMg(CO3)2) by hydrochloric acid leaching, precipitation with CO2 and thermal hydrolysis. Leaching of the dolomite ore in aqueous hydrochloric acid solution was investigated with respect to the effects of time on dissolution of the dolomite sample. The dependence of the observed dissolution rate on pH was established. In the carbonation experiments changes in pH, Ca2+ and Mg2+ concentrations versus time in the effluent solution were determined. Effects of the temperature on the precipitation rate of Ca2+ ions as solid CaCO3 were studied. Experiments were conducted to determine the kinetics of thermal decomposition of MgCl2.6H2O during pyrohydrolysis process. From high purity magnesium chloride brine magnesium oxide
