Pig Iron | International Iron Metallics Association
Pig iron is the product of smelting iron ore (also ilmenite) with a highcarbon fuel and reductant such as coke, usually with limestone as a flux. Charcoal and anthracite are also used as fuel and reductant. Pig iron is produced by smelting or iron ore in blast furnaces or by smelting ilmenite in electric furnaces.

Iron Ore Smelting Process Brighthub Engineering
The ore is loaded into a blast furnace along with measured quantities of coke and limestone. Hot combustion air is supplied to the furnace and some form of fuel used to raise the temperature. The iron is reduced from the ore by carbon in the coke, the limestone aiding slag separation from the molten iron. The slag and molten iron are tapped off from the bottom of the furnace, the slag being ...

A Brief Review of Iron Ore Beneficiation Trace Elements
Ideally iron ore contains only iron and oxygen. In nature this is rarely the case. Typically, iron ore contains a host of elements which are often unwanted in modern steel. Silicon The major effect of silicon is to promote the formation of gray iron. Gray iron is less brittle and easier to finish than white iron.
