摘要： A process for recovering metal values from sulfide ores or concentrates by a fluid bed roast-reduction smelting-converting process which delivers to the reduction smelting furnace either a blend of dead roasted concentrate and green concentrate or a partially roasted concentrate, either feed mixed with a carbonaceous reductant and silica flux, and either feed containing only sufficient sulfur to produce a matte, in which the iron is present as metallic iron, and which has a sulfur deficiency of about 0% to about 25% with respect to base metals, and which is later converted to a low iron matte by blowing and slagging the iron with silica flux.

摘要： A process for the pyrometallurgical extraction of bismuth from a bismuth-bearing material (e.g., ores and concentrates of bismuth in the roasted or unroasted states), in an electric furnace with submerged electrodes in which the sulphur content of the charge constituted of the bismuth-bearing material is controlled so that a matte phase is produced having a bismuth content of between 3 and 20% by weight and a slag phase is produced which is separated from the matte. Under these conditions cheap fluxes (e.g., sand, limestone, iron oxide) can be used whereby the resulting slag has a relatively low corrosivity and high melting point (e.g., 1150.degree.-12000.degree. C.) without excessive losses of bismuth by volatilization.

摘要： A continuous process for refining metal sulfide ores which is carried out by arranging a smelting furnace and a blister furnace, each maintaining discreteness in the reaction zones, wherein a separator is provided subsequent to the smelting furnace so as to limit the function of the smelting furnace to the melting of the raw material and absorption of the copper content in a slag which slag is formed from a subsequent oxidizing furnace into a matte layer, thus achieving the smelting process at a higher furnace rate. The reaction products in the smelting furnace are all tapped out simultaneously without being separated from each other, and transferred to this separator where they are separated and tapped out individually.

摘要： In the processing of nonferrous sulfide ores, the resulting flue gas, which contains sulfur dioxide, is passed through an aqueous scrubber containing calcium sulfate or calcium sulfite. The resulting SO2 collection is several times greater than in the case of prior scrubbing techniques. This system also has application in scrubbing flue gas from sulfur bearing fuel.

摘要： In smelting ores and concentrates of copper or nickel, matte fall is obtained by recycle of ferrous sulfate which is produced when the matte is leached with sulfuric acid. The residue from leaching then contains the copper, nickel or cobalt values in concentrated form. In this method the ferrous sulfate is reduced to ferrous sulfide at elevated temperatures. This is the basis of molten matte, wherein the metal values are collected and then separated from the iron sulfide by leaching. The iron contained in the concentrate is removed ultimately in slag.
