摘要： Method and apparatus for smelting an ore concentrate or the like in which the concentrate is first melted in an oxidizing atmosphere and the smelt is thereafter treated with reducing gases to recover the metal values. One of the features of the present invention resides in conducting the after-treatment by means of blowing reducing gases into the smelt with a plurality of separate lances to provide a lighter slag phase and a heavier metal-containing phase, and separately withdrawing the slag phase and the metal containing phase from the furnace. In a particularly preferred embodiment of the invention, the smelt is aftertreated in the sequence involving first blowing an oxidizing gas thereon, then blowing a neutral gas thereon, and finally blowing a reducing gas thereon prior to separating the slag phase from the metal phase.

摘要： A method for continuously refining impurities from a copper melt wherein molten copper is conveyed sequentially through reduction and oxidation zones where it is reacted with gases to free it from impurities. The method involves passing an oxygen containing gas into contact with a molten copper bath in the form of a vertical jet under controlled pressure conditions, controlled velocity, controlled spacing and the like, resulting in a convective material exchange between the copper bath and the gas before the gas is used to oxidize a reducing gas stream.

摘要： A method and apparatus for smelting an ore concentrate or the like wherein the concentrate is first melted in an oxidizing atmosphere and the smelt is aftertreated with reducing gases to recover the metal values. The improvement consists in positioning a plurality of rows of lances in a smelting reactor in the direction of molten metal flow, the spacing between the rows of lances being substantially greater than the spacing between individual lances in each row. The reducing gas is blown with a high kinetic energy through each lance to cause an area of toroidal bath movement to occur where the gases from each lance impinge against the moving smelt. The spacing between the rows of lances is sufficiently large so that a relatively quiescent zone exists between the areas of toroidal bath movement between each of the rows. The molten metal and a relatively metal-free slag are withdrawn separately from the furnace enclosure.
