<p>Provided is a metal chrome fabrication method in which the chrome recovery yield can be increased and the iron content and P content of the metal chrome that is fabricated as a product can be reduced. This metal chrome fabrication method is provided with the following: a step (S1) in which chromium oxide, aluminum, and lime are put into an electric furnace as raw materials; a step (S1) in which electricity is supplied to the electric furnace, the raw materials are melted, and the chromium oxide is reduced by the aluminum to produce a first metal containing chrome and a first slag, a step (S2) in which the first slag is tapped from the electric furnace, a step (S3) in which a base flux is added to the first metal in an electric furnace, and a step (S4) in which electricity is supplied to the electric furnace, the base flux is melted, and the aluminum remaining in the first metal is oxidized and removed to produce a second metal.</p> |
