Claim 7:
8. A method for recycling carbon dioxide using a system according to claim 1, wherein the method comprises:
chlorinating a calcium-containing silicate and/or a magnesium-containing silicate to obtain calcium chloride and/or magnesium chloride;
mixing the calcium chloride and/or the magnesium chloride with ammonia water and carbon dioxide and performing a carbonation reaction to convert the carbon dioxide into calcium carbonate and/or magnesium carbonate while generating an ammonium chloride solution; and
recovering the ammonium chloride solution generated in the carbonation reaction,
wherein the ammonium chloride solution after being concentrated or hydrogen chloride generated from a decomposition reaction of the ammonium chloride solution is directly used to chlorinate the calcium-containing silicate and/or the magnesium-containing silicate.
