Abstract
Powdered calcium carbonate and/or a solution of magnesium bicarbonate are prepared from a natural mineral containing calcium or magnesium carbonate or both, by heating the mineral to convert the carbonate to oxide, slaking the oxide with water to give hydroxide, reacting the resulting solution or suspension of hydroxide with carbon dioxide in a reactor in which both the hydroxide solution or suspension and the carbon dioxide are forced to flow continuously upwardly under pressure against gravity, and thereafter recovering the powdered calcium carbonate and/or solution of magnesium bicarbonate. The hydroxide solution or suspension may be subjected to vibration, preferably ultrasonic vibration, during the reaction with carbon dioxide as may the oxide during slaking. The carbon dioxide may be derived from the calcination of a naturally occurring carbonate mineral and may be introduced into the reactor through a porous or perforated surface to distribute it in the form of fine bubbles. The calcium carbonate may be recovered by filtration under pressure. The reactor may comprise a tubular reaction space, the longitudinal axis of which does not deviate by more than 15 degrees from the vertical, the average cross-sectional area of which is not more than 1200 cm.2 and the length of which is at least 15 times its average diameter. It may be fitted with a vibrator preferably an ultrasonic vibrator, for vibrating the reactants during the carbonation reaction. The solution of magnesium bicarbonate obtained may be used to prepare magnesium oxide which may be employed to prepare magnesium metal by chlorination and electrolysis of the magnesium chloride so obtained, pure carbon dioxide being a useful by-product.
