ABSTRACT:
Metal carbonates that are insoluble in water but that have a corresponding metal biocarbonate salt that is more than 75% by weight soluble in water are purified by preparing an aqueous slurry of the metal carbonate: introducing carbon dioxide gas to form a corresponding metal biocarbonate solution and heating that solution to form a purified metal carbonate and precipitate it.
