Patent

CA 2522235

A method for obtaining pure copper is provided wherein oxygen is blown onto a copper melt, in a melting furnace lined with refractory material, having a waste heat boiler set onto it, in order to oxidize contaminants contained in the melt and thereby remove them from the melt, and wherein a splash protection device through which water flows is provided above the copper melt, on the inside wall of the melting furnace, which prevents copper that splashes out of the copper melt from penetrating into the waste heat boiler. Boiling water is used for cooling the splash protection device, which water is under a pressure of more than 5 bar and is evaporated, at least in part, as it flows through the splash protection device.
