Blast furnaces produce pig iron from iron ore by the reducing action of carbon (supplied as coke) at a high temperature in the presence of a fluxing agent such as limestone.Ironmaking blast furnaces consist of several zones: a crucible-shaped hearth at the bottom of the furnace; an intermediate zone called a bosh between the hearth and the stack; a vertical shaft (the stack) that extends from ...

Besides the blast furnace process the zinc and lead calcine can be used as feed material to the imperial smelting furnace (ISF). The major difference between a lead blast furnace and the ISF is that in the lead blast furnace the lead oxide is reduced by carbon monoxide which is generated by the combustion of metallurgical coke with air within ...

For lead blast furnace slags, it is therefore appropriate to recover the lead and zinc in separate solutions to subsequently permit effective recovery of both metals. If the metal values were not important then a bulk leach of the two metals or a simple lead leach would be possible to render the slags non-hazardous.

The zinc-lead blast furnace. Sintered zinc and lead concentrates, mixed with metallurgical coke, are charged into the top of a shaft furnace, into which preheated air is blown through nozzles, or tuyeres, at the base (see figure).This procedure is similar to that followed in an iron blast furnace, with the important difference that the major products of reduction here are a zinc-bearing gas ...

Blast Furnace Smelting a metallurgical process carried out in shaft furnaces, used mainly in nonferrous metallurgy for the smelting of lead bullion, copper, copper matte, and nickel matte. The charge is loaded from above and consists of lumped metal-bearing raw material, fluxes, and coke. As the coke is burned and the materials are smelted, the charge ...

During the production of pig iron in a blast furnace, a Zn- and Pb-containing sludge is generated in the air pollution control system. This toxic waste can be landfilled after dewatering and pretreatment, which is very costly. The sludge particles contain large amounts of Fe and C that could be recycled in the furnace. However, the Zn content of the sludge is high, and the Zn input to the ...

Features: High heat efficiency: furnace burden heated by the waste heat of the off-gas. High recovery rate: The molten lead and slag will be separated completely in blast furnace hearth, because the blast furnace hearth has higher temperature and more obvious slag line than rotary furnace to sedimentate the lead metal from slag.

A crucial component in creating lead is the blast furnace. The furnace is a giant steel stack that typically gets lined with refractory bricks. Its purpose is to create liquid iron from chemically transforming iron oxides. Limestone, coke and iron ore are also thrown into the blast furnace.

The lead content of matte could be decreased to as low as 9.0 to 11.6 wt-pct (2.3 to 3.0 At. pct) at 1,000 deg c, depending on composition. The effect of oxygen in the matte on lead recovery from iron-saturated mattes was also investigated. The addition of oxygen further decreased the lead content, and higher recoveries of lead were obtained.

Blasts furnaces are used for smelting during the production of metals such as iron, lead, zinc, and copper. A blast furnace works by blasting hot air up through the furnace while fuels, limestone, and ore move continuously through the top of the furnace. The method used in blast furnaces have been used since the 1500's.

Blast furnaces are similar to furnaces, but can smelt only ore blocks and tools/armor made of iron, gold or chainmail. Smelting equipment yields one iron or gold nugget from their respective materials. Once an item and a fuel are placed into the blast furnace, the block state changes to lit and the item is smelted twice as fast as a regular furnace. Fuel is also used at double the rate of ...
