Abstract: This invention relates to a process for the direct smelting of ores, metallic compounds and the like with the use of a heat plasma. This process can be readily conducted with a simple installation irrespective of the shape of the object being smelted and without the necessity of using any plasma generating gas. The process of the invention is characterized by applying a multiphase AC voltage to a number of graphite electrodes to thereby cause arc discharge in the air and directly impinging a highly reductive non-transferred plasma arc generated by the oxidative decomposition of the graphite electrodes against the object from the tips of the electrodes.

Abstract: A method and apparatus for producing, in a reactor, a suitable prereduced product for final reduction from material containing metal oxide. The material is preheated in a fluidized bed by means of hot gases from a subsequent prereduction stage. The hot material is smelted and prereduced in a flame chamber utilizing hot reducing gases from a subsequent final reduction stage. The prereduced material is completely reduced in the final reduction stage.

Abstract: A novel mixed binder system for agglomerates is disclosed. The agglomerates are suitable for use in the production of metals and alloys in a carbothermic reduction process such as the production of silicon in a direct arc furnace by the carbothermic reduction of silica. The agglomerates prepared using this mixed binder system have high physical strength over a wide temperature range. The mixed binder system consists essentially of a primary binder selected from the group consisting of coal tar pitch, asphalt, and petroleum pitch and a secondary binder selected from the group consisting of lignosulfonate salts, carbohydrates, and silicates. !

Abstract: A process for the smelting reduction of oxide ores, in particular iron ores, employs a mixture of the finely divided ore with equally finely divided reductant, which in the case of iron ores preferably is a coal. The mixture is fed into the interior of a heated tubular reaction vessel (10) and moved positively through a heated reaction zone by a screw conveyor 14 embedded in the charge. The conveyor (14) breaks away any accretions that stick to the vessel wall before they can built to a size that will stall the conveyor (14). The particles are in the range 75-1400 micrometers with a preferred size of at least 95% less than 600 micrometers, and the preferred ratio of ore to reductant is in the range of ratios 18:82 to 30:70. The reduced iron can be fed directly into a melting furnace (34) for separation of metal and non-metal, it can be powdered and separated magnetically or it can be briquetted. Multiple screw conveyors can be used to move multiple charges and the process can be used with nickel ores and in the production of metallurgical coke.
