Abstract
In the refining of metal in a bath of the molten metal, oxygen is injected into the molten metal in a stream adjacent to a stream of a protective fluid which conveys a particulate flux, which is reactive with oxygen, into the molten metal; in this way the oxygen and particulate flux are safely introduced into the interior of the molten metal.
