ABSTRACT A highly compact and efficient tilting crucible furnace and smelting method is disclosed for use in the direct smelting of a precious metal containing material. A furnace body having a refractory lined cavity which has a top opening is pivotally mounted on a support frame to allow tipping thereof. A cover having a first opening to receive a gas burner and a second multi-purpose opening therein is rigidly attached to the body. A gas burner attached to the cover provides a downwardly directed oxidizing flame into the cavity to oxidize iron which is added to the cavity and other impurities in the precious metal containing material. A flux is provide to provide a thoroughly liquid mixture and after heating, the molten mass is poured through the multi-purpose cover opening into a mold. As the mold cools, a dore button of precious metal settles to the bottom of the mold and slag containing impurities forms on the top.
