摘要： A method of smelting zinc in a blast furnace wherein the furnace is charged sequentially with separate loads of coke and agglomerated zinc oxide material, wherein, for a major proportion of the total operating time which is devoted to coke charging, from 25% to 50% by weight of the coke charged is directed towards the center of the furnace shaft so as to promote a coke-rich charge core, the remainder of the coke charged being directed towards the furnace walls, and wherein for a minor proportion of the said total operating time from 80% to 95% by weight of the coke charged is directed towards the walls of the furnace shaft to aid accretion melting, the remainder of the coke charged being directed towards the center of the furnace shaft.
摘要翻译：一种在高炉中熔炼锌的方法，其中炉子依次加入焦炭和附聚的氧化锌材料，其中，对于焦炭加料的总操作时间的主要比例为25％至50％重量的焦炭被引导到炉子轴的中心，以便促进富含焦炭的加料芯，其余的焦炭被引导到炉壁，并且其中对于所述总操作中的较小比例焦炭重量的80％至95％的时间指向炉轴的壁以帮助增加熔化，其余的焦炭被引导到炉心的中心。

摘要： A method and recovering method of recovering zinc oxides and other metal oxides having an injection chamber where a mixture of natural gas and oxygen is formed and then ignited to form high temperature combustion gases of greater than 2000° C. with a high concentration of carbon monoxide. Then, the mixture is transported through a quiescent chamber to a feed chamber where the ignited high temperature combustion gases are mixed with finely divided material, including EAF dust. The mixture is transported to a reaction chamber, wherein zinc vapor and other metal vapors and molten slag particles are formed. The zinc vapor and other metal vapors are separated from the molten slag particles and transported to an insulated plenum. Zinc vapor and other metal vapors are mixed with air and become airborne zinc oxide and other metal oxides. The airborne zinc oxide and other metal oxides are collected.

摘要： A method for producing lead involves feeding lead concentrate, flux and solid fuel passing to a feed preparation unit. The prepared, mixed feed is then passed to a lead smelting furnace, such as an ISASMELT furnace or other top entry, submerged lance furnace. Air or oxygen, is injected into the molten charge in the ISASMELT furnace via the submerged lance. The feed mixture is converted into lead bullion and a lead-containing slag. The slag removed from the furnace is formed into lumps having a desirable size range. The slag lumps, together with coke and flux are fed into a blast furnace. In the blast furnace, the slag is converted into lead bullion and discard slag. The lead bullion removed may be subsequently fed to a lead refinery for further treatment.

摘要： The blast furnace in the present invention comprises a V-shaped or an inclined hearth, tuyeres disposed along said hearth, a tap hole for discharging matte and/or slag, said tap hole being disposed at the lowest part of the hearth, and dampers having V-shaped or inclined fore end, each of said dampers being disposed to agree with said tuyeres. The present blast furnace, when employed for smelting by feeding briquetted Zn bearing materials as the material thereto and blowing preheated air therein through the tuyeres disposed along the hearth, displays an improved smelting efficiency in separating and recovering volatile valuable metals and non-volatile valuable metals.
