摘要： A method making pig iron employs an in-bath direct reduction performed in a metallurgical vessel which has above it a melting cyclone in which iron-oxide-containing material fed thereinto is pre-reduced by hot reducing gas coming from the vessel. Molten material passes downwardly from the melting cyclone into the vessel. In order to recover zinc from a dust containing zinc and/or zinc oxide, the dust is fed into the melting cyclone. Zinc is allowed to vaporize out of the dust into the hot gas in the melting cyclone. The hot gas containing zinc is discharged from the melting cyclone, and zinc-containing material is extracted from this hot gas.

摘要： The present invention relates to a method for recovering zinc from zinc-containing materials, especially from zinc-containing materials recovered from waste gases in metallurgical smelting processes. Particulate zinc-containing materials are agglomerated together with a carbonaceous reduction material and optionally slag forming materials, and are supplied to a gas tight closed electrothermic smelting furnace containing a molten bath kept at a temperature between 1200.degree. and 1700.degree. C. in which the agglomerates are smelted and subjected to selective reduction and volatilization of zinc and other volatile metals. An inert slag phase and optionally a liquid metal phase are tapped from the smelting furnace, and zinc and other volatile metals are recovered from the waste gas from the smelting furnace by condensation. In order to prevent reoxidation of metallic zinc the particulate zinc-containing materials are agglomerated together with a carbonaceous binder which cracks at a temperature below 700.degree. C. and forms carbon black, and that the temperature in the gas atmosphere in the smelting furnace is kept above 1000.degree. C. in order to maintain a volume ratio between CO.sub.2 and CO in the gas atmosphere in the smelting furnaces below 0.3.

摘要： The invention relates to a method for utilizing zinciferous waste from metal smelters, such as steel smelters, so that the transmission of fluorides to the highly zinciferous secondary dusts is prevented during the treatment of the gas obtained from the waste smelting furnace. Fluorides are extremely harmful for the zinc process, and therefore it is important to prevent them from entering the process. By adjusting, according to the invention, the temperature and composition of the exhaust gases created in the smelting treatment of zinciferous dusts and other waste, the fluorides and the highly zinciferous fraction are obtained in different end products. Other valuable metals are recovered from the metal layer created on the bottom of the furnace.
