Abstract
An integrated process for carbon dioxide capture, sequestration and utilization, includes a) providing an aqueous slurry with a particulate solid including an activated magnesium silicate mineral; b) contacting a CO-containing gas stream with the aqueous slurry to provide a slurry comprising a magnesium ion enriched carbonated aqueous liquid and a magnesium depleted solid residue; c) subjecting at least part of the magnesium depleted solid residue to a particle size classification process that separates the magnesium depleted solid residue into a fine particle size fraction and a coarse particle size fraction; d) subjecting the coarse particle size fraction to a particle size reduction process; e) providing an aqueous slurry comprising particle size reduced fraction from step d) and repeating step b), wherein this step e) does not include using fine particle size fraction from step c); and f) precipitating magnesium carbonate from magnesium ions dissolved in b) and e).
