Blast furnacing, smelting and direct iron reduction are the current ironmaking processes. Ironmaking Blast Furnace. Iron is made by reacting iron ore (iron oxide and impurities), coke (a reductant) and limestone (CaCO 3) in a blast furnace. Iron ores with lower iron content such as taconite are first processed to concentrate the iron level and drive off volatile impurities. The iron ore is

01.01.2010· The zinc blast furnace process is one of the newest pyrometallurgical processes developed by Imperial Smelting Processing Limited in England. In the ISP, ZnO is reduced by carbon to produce zinc. In the reduction carried out by an ISP blast furnace, the zinc that is evolved in the form of a vapor is condensed by using molten lead. Some of the advantages the ISP include: (i) it is possible to simultaneously smelt

The blast furnaces used in the Imperial Smelting Process shortly called ISP were developed from the standard lead blast furnace, but are completely sealed. This is because the zinc created by these furnaces is obtained as the metal from the vapor phase, and the presence of oxygen in the off-gas would result in the formation of zinc oxide.

In blast furnace ironmaking coal is not as strong as coke, and crushing will cause a decrease in the permeability of the blast furnace. The calorific value and carbon content of some anthracite coals are higher than coke, but there are more harmful impurities such as phosphorus and sulfur in coal. As the combustion enters molten iron, the quality of subsequent steel will be affected. Comparing

Then came the change from cold blast, charcoal furnaces to hot blast, coke furnaces in the mid-1800s which brought iron making into the modern era. The better understanding of iron making reactions and improved equipment evolved into the hard-driving furnace operation centered in the 1880s to 1900s. Finally, the revolution in scientific applications to iron smelting, the installation of more

A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally pig iron, but also others such as lead or copper. Blast refers to the combustion air being "forced" or supplied above atmospheric pressure. [1] In a blast furnace, fuel (coke), ores, and flux (limestone) are continuously supplied through the top of the furnace, while a hot blast of air

Our ISP (Imperial Smelting Process) blast furnace, which can smelt zinc and lead simultaneously, uses massive coke as a heat source and a reducing agent, like the iron blast furnace. By injecting natural gas (LNG, hydrocarbon gas) from the tuyeres of the ISP blast furnace, a part of lump coke will be replaced to reduce CO2 gas emissions. In addition, a part of lump coke is replaced by blowing
