First, the iron ore is prereduced in a shaft furnace or a fluidized bed, depending on the process and the type of ore used. Second, the prereduced ore is charged into a molten bath into which coal and oxygen or air are also introduced. The gases leaving the smelter are used to perform the reduction in the prereduction vessel.
Types of dams Learn more about the types of dams. When a dam is built, it is for the purpose to contain tailings. This is the starter dam. As more tailings are deposited, new layers are added to the starter dam (this is called the upstream construction method). There are different types of construction methods.

Types of iron ore. The major rock types mined for the production of metallic iron are massive hematite, pisolitic goethite/limonite, which provide a ''highgrade'' ore, and banded metasedimentary ironstone, magnetiterich metasomatite, to a much lesser degree, rocks rich in siderite, rocks rich in chamosite which provide a ''lowgrade'' ore.
Pig iron: Raw iron, the immediate product of smelting iron ore with coke and limestone in a blast furnace.
