METHOD OF STABILIZING LEACHABLE COMPOUNDS IN A CARBONATE BONDED MATRIX
Method of producing a carbonate bonded article, comprising preparing a reactive mixture comprising a particulate mineral source and an aqueous source, and reacting the reactive mixture with carbon dioxide to form a mineral matrix comprising carbonates. The particulate mineral source comprises a leachable compound, the leachable compound comprising one or more elements selected from: As, Ba, Cd, Cr, Co, Cu, F, Hg, Mo, Mn, Ni, Pb, Sb, Se, V and Zn. The reactive mixture comprises a reducing agent, wherein the reducing agent comprises one or more of a sulfide, disulfide and polysulfide compound that reacts with the particulate mineral source and the pH of the reactive mixture is at least 10.
