Abstract
This application provides a process for mineral carbonation, which process comprises the steps of: providing a bed of hydroxylated magnesium silicate mineral particles in a heating vessel; agitating the bed of particles under conditions of a sub-atmospheric pressure and at a temperature of at least 600° C. to produce particles of dehydroxylated magnesium silicate mineral; and reacting the dehydroxylated magnesium silicate mineral with carbon dioxide, carbonate ions and/or bicarbonate ions to form magnesium carbonate. This application also provides a reactor system for carrying out the process, which includes () mineral from mine, () hydroxylated magnesium silicate mineral, () crushing, grinding, sizing, () agitated bed of particles, () external heating, () vacuum system, () from carbon source, () carbon dioxide or carbonate or bicarbonate ions in solution, () carbonation reactions, () carbonate product, () pre-heat, () heat recovery, and () magnetic fraction.
