(3) Sponge Iron Process: As the name implies, the spongy iron is obtained by the reduction of lumpy iron ore or iron ore pellets from the oxide form into the metallic state. The iron content of the product so obtained varies from 90% to 94% and the balance represents the traces of gangue and residual iron
Pig iron, also known as crude iron, is an intermediate product of the iron industry in the production of steel which is obtained by smelting iron ore in a blast furnace. Pig iron has a very high carbon content, typically 3.8–4.7%, along with silica and other constituents of dross, which makes it very brittle and not useful directly as a material except for limited applications. The traditional shape of the molds used for pig iron ingots is a branching structure formed in sand, with m

What you are most likely to get is a good supply of iron ore that can be converted into pig iron in a blast furnace. Generally, pig iron has a composition of 92-94% iron and the rest carbon along with other minerals.
Jessica Ellis Pig iron begins with iron ore and other raw materials. Pig iron is a metal material that results when iron ore, charcoal from coal, and limestone are melted together under intense air pressure.When the combined material cools, it forms a high-carbon product known as pig iron.The cooled material is rarely used by itself, as the large amount of carbon makes the material brittle and ...
Pig iron is the basis of a majority of steel production. A majority of steel produced in the world is created through pig iron production. Sponge iron. Removing oxygen from the ore by a natural process produces a relatively small percentage of steels in the world. This process uses less energy and is a natural chemical reaction method.
iron processing - iron processing - Ores: Iron ores occur in igneous, metamorphic (transformed), or sedimentary rocks in a variety of geologic environments. Most are sedimentary, but many have been changed by weathering, and so their precise origin is difficult to determine. The most widely distributed iron-bearing minerals are oxides, and iron ores consist mainly of hematite (Fe2O3), which is ...
