Coke is used as a fuel and a reducing agent in melting iron ore. It is produced by baking coal until it becomes carbon by burning off impurities without burning up the coal itself. When coke is consumed it generates intense heat but little smoke, making it ideal for smelting iron and steel. Prior to the 1880's, steel was produced using charcoal. …
Iron ore must go through a lengthy pre-processing stage before it can be pelletized – a series of steps that work to beneficiate and concentrate low-grade ores. This process varies depending on the ore source, but typically involves various stages of crushing and grinding to reduce the size of the iron ore.

Iron ore reduction is an important process in the iron/steel-making industry, where iron ore is reduced to metallic iron, usually with coal, coke, natural gas, CO, or hydrogen as the reducing agents. Fig. 1. Scheme of the CBGIOR process ( Wei et al., 2017a,b ).
Iron making evolved over a few thousand years. Using the ancient "bloomery" method, iron ore was converted directly into wrought iron by heating the ore while at the same time melting the ore's impurities and squeezing them out with hand hammers. This is also called the "direct process." By the 1100s water-powered hammers …
Extraction of iron from its ore is the third and the penultimate process in the Metallurgy. The extraction of metals and its isolation occurs over a few major steps:
This consistent rise in pig iron production has driven the demand for iron ores.
