Document Type and Number:

Japanese Patent JP5020488

Kind Code:

B2

Abstract:

To provide a hydrotalcite-like compound obtained from dust generated from an electric furnace for producing calcium carbide as a raw material, its manufacture method, and an anion remover.

This hydrotalcite-like compound is manufactured by using dust, generated from an electric furnace for producing calcium carbide, as a raw material. This method for manufacturing a hydrotalcite-like compound comprises an extraction step of acid treating the dust generated from the electric furnace for producing calcium carbide to extract an acid-soluble metal component and a precipitation step of adding aluminum ions to a solution containing the acid-soluble metal component and adjusting pH to precipitate the generated product. This anion remover contains the hydrotalcite-like compound.
