摘要： Disclosed is a metal manufacturing method whereby the metal powder component is separated from a mixture of metal salt and metal powder, wherein the metal manufacturing method is capable of reducing the amount of energy required for manufacturing. A mixture (1) of metal salt and metal powder is supplied to the starting material input region (12) of a first hearth (10) which is partitioned by means of a skimmer (11). A plasma (19a) is used to perform heating to a temperature equal to or greater than the melting point of the metal salt and lower than the melting point of the metal powder, and this temperature is maintained, producing an upper layer (a molten salt (2) of molten metal salt) and a second, lower layer (a highly concentrated solid-liquid mixture (3) with an increased concentration of metal powder). Next, the upper layer, the molten salt (2), is discharged from a discharge port at the top of the first hearth while the lower layer, the highly concentrated solid-liquid mixture (3), is discharged from a lower layer discharge port (14). Next, the highly concentrated solid-liquid mixture (3) is heated to a temperature equal to or greater than the melting point of the metal powder and the temperature is maintained, and the metal powder within the highly concentrated solid-liquid mixture (3) is melted to produce molten metal, which forms an upper layer (molten salt (4)) and a lower layer (molten metal (5)). The molten metal (5) is separated from the molten salt (4), and the molten metal (5) is solidified into an ingot (6).

摘要： Provided are a fusing method in which metal powder is fused and separated from a mixture of metal salt and metal powder, and fusion apparatus which employs this method, wherein it is possible to use moving plasma having excellent energy efficiency. A lining part (15) comprising a second metal is inserted in such a way as to cover the side walls and upper edges of the side walls of a bath (10) comprising a first metal. Then the mixture (1) comprising metal salt and metal powder is introduced into a mixture introduction region (16) of the bath (10) which is partitioned by a skimmer (13) and, maintaining a state where the whole of the mixture (1) has been fused using the plasma (19a), two layers, namely an upper layer (fused salt (6)) where the metal salt has been fused) and a lower layer (fused metal (7)) are formed as a result of the difference in specific gravities. The formation of a fused salt layer which is an insulator by the solidification of the fused salt (6) on the inner surface of the bath (10) is prevented by maintaining the temperature of the portion of the lining part (15) in contact with the fused salt (6) above the melting point of the fused salt (6).
