  • Patent number: 9051189
    Abstract: Disclosed is a method for solidifying carbon dioxide into carbonate, in which carbon dioxide is stably converted into and solidified into carbonate (mineral facies) by using steel slag or natural mineral by extracting an alkali component by supplying an ammonium salt solvent as an extraction solvent to raw slag and injecting carbon dioxide into an extract solution supplied to a carbonation reactor to produce carbonate precipitate from the extract solution through the induction of a conversion reaction of the carbon dioxide into the carbonate precipitate. Then after the above two step are performed at least one an acetic acid solvent is supplied as an extraction solvent to the raw slag so as to finally extract an alkali component; and carbon dioxide is injected into an extract solution to produce carbonate precipitate from the extract solution through the induction of a conversion reaction of the carbon dioxide into the carbonate precipitate.

  • Publication number: 20140072503
    Abstract: An object of the present invention is to provide a fine crystal particle production method and device that are excellent in mixing efficiency. This object is achieved by a method for producing fine crystal particles, comprising: a swirl flow producing step at which a swirl flow of liquid a comprising reactant A is supplied into a cylinder having a circumferential surface partially or wholly composed of a porous membrane; and a reaction step at which liquid b comprising reactant B which is reactive with the reactant A is supplied through the porous membrane to the swirl flow to effect mixing, whereby the reactants A and B are reacted to precipitate fine crystal particles.

  • Publication number: 20140041550
    Abstract: An object of the present invention is to provide a process to grind at least one mineral material in the presence of ceria (CeO2)-containing zirconium oxide grinding beads having a specific ceria content (of between 14 and 20% by weight relative to the total weight of said bead, preferably of between 15 and 18%, and most preferably of approximately 16%), and a specific average grain size (of less than 1 ?m, preferably of less than 0.5 ?m, and most preferably of less than 0.3 ?m), wherein such beads are more resistant to wear than conventional beads of the prior art. Another object of the present invention lies in the ground material in the form of an aqueous suspension and in the form of a dry product. Another object of the present invention lies in the uses of such products in any sector making use of mineral materials, and notably in the paper, paint and plastic industries.

  • Patent number: 8603428
    Abstract: The present invention concerns a method for producing calcium carbonate containing the steps of extraction of alkaline industrial waste or by-products using as a first extraction solvent an aqueous solution of a salt formed from a weak acid and a weak base, whereby a vanadium-enriched first residue is allowed to settle and a calcium-rich first filtrate is formed, filtration, whereby the first filtrate is separated from the first residue, carbonation of the calcium-rich first filtrate using a carbonation gas, whereby calcium carbonate precipitates and a second filtrate is formed, and a second filtration, whereby the calcium carbonate is separated from the second filtrate. Further, the present invention concerns a method for extracting calcium carbonate and vanadium from alkaline industrial waste or by-products.
