MAGNESIUM COMPOUNDS FROM MAGNESIUM SILICATES

摘要

A process for the leaching of magnesium compounds from calcined magnesium silicates having initially a phyllosilicate structure; the magnesium silicates show a MgO to SiO2 ratio higher than 1.0 on a weight basis; the leaching is done with carbon dioxide on a slurry of ore in water at substantially ambient temperature and at substantially atmospheric pressure.
