METHOD FOR THE PRODUCTION OF A HIGH-PURITY CONCENTRATED MAGNESIUM CHLORIDE SOLUTION BY ACID LEACHING AND NEUTRALIZATION |
摘要 |
<p>The present invention is concerned with a method for the extraction of magnesium from magnesium-containing materials such as magnesite, dolomite and silicates materials like serpentine residues, products from the amphibole or pyroxene group. The magnesium-containing material is first leached in at least one leaching reactor, and subsequently submitted to a series of neutralizing steps in separate reactors under controlled pH and oxydo-reduction potentials. The slurry produced is filtered to produce a substantially pure magnesium chloride solution containing less than 1 ppm of each contaminant present therein.</p> |
