Abstract: A method for efficiently recovering a platinum group element comprises melting copper-iron scrap containing a platinum group element, forming the melt into two liquid phases, a molten copper phase containing at least one rare metal selected from the group consisting of Nd, Pr, and Dy and a molten iron phase having a carbon concentration of at least 1 mass %, with the carbon contained in the molten iron phase being derived from carbon contained in the melt, separating the two liquid phases, recovering the molten copper phase, and separating and recovering from the molten copper phase a platinum group element dissolved therein. The copper-iron scrap may contain a rare metal, or a member containing a rare metal may be added to the melt with a preferred total concentration of rare metals in the melt being at least 1 mass %.

Abstract: A gasification and melting furnace for wastes has a vertically movable furnace center lance disposed along the axis of the furnace and adapted to blow off a combustion sustaining gas downward into the furnace. One or more stages of upper tuyeres are disposed so that the angle at which the combustion sustaining gas is blown off into the furnace is displaced from the furnace axis direction, and one or more stages of lower tuyeres projected into the furnace so as to blow off a combustion sustaining gas or both combustion sustaining gas and fuel toward the furnace axis. Formation of a low temperature region in the furnace are prevented and a fire spot is concentrated on the combustion of wastes. As a result, molten slag and various metals, as well as an energy gas, which are high in added value, can be recovered stably.

Abstract: By using a gasification and melting furnace for wastes having a vertically movable furnace center lance disposed along the axis of the furnace and adapted to blow off a combustion sustaining gas downward into the furnace, one or more stages of upper tuyeres disposed so that the angle at which the combustion sustaining gas is blown off into the furnace is displaced from the furnace axis direction, and one or more stages of lower tuyeres projected into the furnace so as to blow off a combustion sustaining gas or both combustion sustaining gas and fuel toward the furnace axis, it is possible to prevent the formation of a low temperature region in the furnace and concentrate a fire spot for the combustion of wastes. As a result, molten slag and various metals, as well as an energy gas, which are high in added value, can be recovered stably.

Abstract: The method of the invention comprises a method of melting tin-plated iron type scrap using tin-plated iron type scrap of loose packing as a portion of the iron type scrap and conducting melting while controlling the post combustion ratio of the gas by adjusting the amount of the combustion sustaining gas blown from the secondary tuyeres and a method of melting tin-plated iron type scrap packing the tin-plated iron type scrap prior to the non tin-plated iron type scrap and conducting melting while retaining the tin-melted iron type scrap between the coke packed layer and the non tin-plated iron type scrap packed layer.

Abstract: A method for manufacturing molten pig iron is disclosed which comprises:forming a packed bed of coke in a vertical furnace having a charging port in an upper portion thereof for charging raw materials and discharging gases, one or more primary tuyeres in its lower portion, and one or more secondary tuyeres in a wall of the furnace at a level above the primary tuyere, the packed bed of coke extending higher than the level of the primary tuyere;forming a packed bed of scrap and iron ore atop the packed bed of coke to a level which extends above the secondary tuyere; andblowing an oxidizing gas through the primary tuyere and the secondary tuyere to melt and reduce the scrap iron and iron ore.
