摘要： Lead is recovered from sulphidic lead raw-material containing impurities of the kind bismuth, arsenic, antimony and tin, by flame-smelting the material with an oxygen-containing gas. The oxygen potential and temperature are adapted during the flame-smelting process so that the product formed thereby comprises substantially a lead-sulphide melt substantially free of volatile, sulphidic and metallic impurities of the said kind. The lead-sulphide melt is brought into contact with an oxidic lead material substantially free of impurities of the aforementioned kind, while oxidizing the sulphide-sulphur content of the material and forming a melt substantially free of sulphur. Lead is recovered from the melt by separation, optionally after subjecting the melt or a part thereof to a reducing process.

摘要： The invention relates to a method for recovering the metal values from materials containing at least one of zinc and tin, by smelting the starting materials under oxidizing conditions and reducing the resultant molten bath. The starting materials are first smelted in a furnace while adding flux, to form a slag which is sluggish at selected reduction temperatures and has a low lead contents. The reduction process is carried out while charging solid carbonaceous reduction agent and optionally also sulphur- and/or chlorine-donor material to the slag. The reduction agent and optionally supplied donor material is brought into suspension with the slag, and this suspension is sustained at least during the latter phase of the reduction period, at which the lead content of the slag has fallen to beneath about 1-2%, during which phase the reduction of zinc and tin takes place. Zinc is recovered from the furnace in the form of zinc vapor, while tin optionally is removed as volatile tin sulphide, chloride or oxide, and lead and any other metal values present in the starting materials are recovered as a molten lead phase.

摘要： A method is disclosed for converting an arsenic-containing waste product to a depositable, substantially arsenic-free form by fuming-off the arsenic content thereof. The method comprises melting the waste product under oxidizing conditions in a furnace to form an oxidic slag melt; causing turbulence of the melt, while maintaining a reducing atmosphere supporting the formation of arsenic (III) oxide at the furnace temperature driving-off arsenic content of the waste product substantially in the form of gaseous arsenic (III) oxide; separating the formed oxide by condensation and recovering the same and removing from said furnace a substantially arsenic-free depositable slag.

摘要： A process for the treatment of complex metal sulphide materials and for the recovery of metal values from such materials. The process involves first subjecting the material to a leaching process under conditions such that sulphide-sulphur is oxidized to sulphate and such that oxidized iron and impurities such as As will pass into solution, whereafter the leaching residue is melted for conventional pyrometallurgical recovery of the metal values.Different embodiments of the process provide for the recovery of precious metal values from refractory materials containing such values and for the recovery of metal from complex copper concentrate and complex nickel concentrate.

摘要： The metal content of complex sulphidic metal raw material is recovered therefrom by means of an autogenous flame-smelting process, preferably carried out in a vortex, with an oxygen-containing gas. The raw materials are smelted in a furnace in the presence of an excess of oxygen and together with an addition of an acid slag former, such as silica, to form a melt which is rich in metal-oxide silicate and poor in sulphur. Any metal phase formed in the furnace is separated from the silicate phase, and non-iron metals present in the silicate phase are recovered therefrom by selective reduction.

Date Mar. 8, 1979.A method of producing blister copper from raw material containing antimony. The invention is characterized in that a slag is separated from copper matte formed by smelting the raw material. Thereafter the matte is brought into contact, under violent agitation preferably in a rotary converter of the Kaldo type, with a substantially inert gas in a quantity sufficient to reduce by volatilization the antimony content of the copper matte and, possibly, also the content of other impurities such as bismuth, arsenic and zinc to a level acceptable when performing the subsequent converting process, so as to obtain the desired blister copper product, preferably a maximum content of antimony, 0.04 percent by weight and of bismuth 0.03 percent by weight. The rotary converter is suitably operated with a rotation corresponding to a peripheral speed of approximately 0.5-7 m/s, preferably 2-5 m/s.

摘要： The invention relates to a method for producing metallic lead from lead-containing starting materials by an oxidizing smelting process and subsequent reduction of the resultant oxidic molten bath. The reduction is effected with solid carbonaceous reduction agent present in the melt, and it is ensured that solid carbonate-containing material, preferably limestone, dolomite or soda ash, is also present in the melt, together with the reduction agent.The method can be applied for working-up lead-starting materials of sulphidic, oxidic or sulphatic kind. In addition, the method can be applied to advantage for working-up lead-carbonate containing starting materials, where at least a part of the carbonate-containing material may comprise lead-starting material.
