The invention relates to a method for manufacturing a melt launder to be used for transferring molten phase such as slag, matte, or metal formed in a process for the production of metals. The invention also relates to a melt launder to be used for transferring molten phase such as slag, matte, or metal formed in a process for the production of metals. The melt launder comprises a launder body of metal, a flow channel for molten phase, a refractory lining for lining the launder body of metal so that the refractory lining at least partly forms a flow surface for molten phase in the flow channel for molten phase, and a layer of steel between the launder body of metal and the refractory lining.
