摘要： Method for converting metallic silicate minerals to silicon compounds and metal compounds via a conversion reaction, characterized in that the conversion reaction is performed in a gravity pressure vessel (GPV), wherein: the GPV comprises two channels having separate entries on the upper side of the GPV and which channels are mutually connected on the bottom of the GPV, and wherein a dispersion of solid particles of the silicate minerals in water is carried into the GPV in a descending flow, one or more reactants for the conversion reaction are added to the dispersion, and the silicon compounds and metal compounds formed during the conversion reaction are carried away via an ascending flow of the GPV. The method provides a method for sequestration of carbon dioxide, wherein the heat produced can be utilized to form a concentrated gas flow of carbon dioxide prior to sequestration.
