Method and apparatus for the pyrometallurgical treatment of fine grained solids to produce molten products |
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/m2xsec 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.
