Patent ID: 8795508

Claim:
A method of sequestering carbon dioxide produced by a source, comprising: (a) obtaining a hydroxide salt in an aqueous mixture: (b) admixing the hydroxide salt with carbon dioxide produced by the source under conditions suitable to form a first carbonate salt in a first admixture; (c) chlorinating a group-2 silicate mineral with hydrochloric acid under conditions suitable to form a corresponding group-2 chloride salt, water, and silicon dioxide; (d) admixing the group-2 chloride salt with the first carbonate salt under conditions suitable to form a group-2 carbonate salt in a second admixture; and (e) separating said group-2 carbonate salt from the admixture, wherein the reaction of step (d) occurs in an electrochemical cell which generates a first source of electrical energy, and whereby the carbon dioxide is sequestered into a mineral product form.
