摘要： A method and apparatus for the pyrometallurgical treatment of fine grained solids such as non-ferrous metal ore concentrates with an oxygen-containing gas wherein the solids are mixed with the gas to form a suspension which is blown through a nozzle into a reaction chamber such as a vertical melting cyclone. In the reaction chamber, the solids are brought to reaction and melted. The invention is concerned with injecting a particle stream through the reaction zone as a focused open jet having mass flow velocity of greater than 50 kg/m.sup.2.sec and having a linear speed of more than 35 m/sec. The particle stream is ignited by the hot combustion gases thereof or by a pilot flame. In a preferred embodiment of the invention, the particle stream is directed along a horizontal secant of the chamber to the opposite wall.

摘要： A method and apparatus for reducing molten metals and/or slags thereof which involves top-blowing at least one reduction gas stream wherein fine grained coal or coke particles and injected for covering the surface of the molten metal beyond the blow impression formed by the reduction gas stream. The particles of the stream are at least partially gasified into a carbon monoxide (CO) contained reduction gas stream before they hit the metal surface, so that a mixture of carbon monoxide and coke is blown onto the metal surface together with the reduction gas stream. The coke particles are then radially moved toward the outside of the blow impression at all sides to form a thin veil beyond the perimeter of the blow impressions.

摘要： A method and apparatus for implementing pyro-metallurgical processes, such as those involved in the reaction melting of fine grained solids or for the after-treatment of melts wherein an exothermically reacting solids/gas mixture is conducted through an acceleration jet as a heterogenous stream and is blown onto a melt contained in the furnace. The jet stream is ignited immediately upon discharge from the jet and a sharply focused or highly concentrated particle stream having a high surface power density (high mass flow velocity) and a high temperature is impacted against the melt. This results in the melt being subjected to localized intensive movement and is simultaneously heated. The method is suitable for the reaction melting of sulfidic or oxidic non-ferrous metal concentrates as well as for the reduction and/or depletion of non-ferrous metal containing slags, and for the reduction of metal melts.

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： 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.
