METHOD AND APPARATUS FOR TREATING MAGNESIUM FINE POWDER

Document Type and Number:

Japanese Patent JP2005008480

Kind Code:

A

Abstract:

To provide a method and an apparatus for treating magnesium fine powder by which magnesium is separated and recovered.

The magnesium fine powder is dissolved in an acid solution and an alkaline solution is charged thereinto to form magnesium hydroxide. The magnesium hydroxide is flocculated/settled with a flocculant and is dehydrated. As a result, magnesium is recovered as a flocculated settled material of magnesium hydroxide in which a trace quantity of the flocculant is incorporated and is easily recycled without necessitating the separation of a by-product.
