ABSTRACT:
A process for removing iron contamination from molten magnesium by adding to the molten magnesium a mixture of a boron-containing compound and a flux. The boron-containing compound includes, for example, elemental boron, boric acid, and boron oxide. The flux is a conventional magnesium flux. The flux and boron-containing compound mixture is prepared by any suitable means and then added to the molten magnesium at melt temperatures of from about 650.degree. C. to about 700.degree. C. The iron contamination in the magnesium product can be reduced for example from about 400 ppm to less than about 10 ppm.
