Iron processing
Iron processing - Ores, Smelting, Refining: 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 …

Extraction of Iron | Metallurgy | Blast Furnace and Reactions
This is even harder than pig iron. Wrought Iron/ Malleable Iron. Wrought iron is the purest form of iron available commercially available and is prepared from cast iron by heating cast iron in a furnace lined with Haematite (Fe 2 O 3). The Haematite reacts with Carbon in the cast iron to give pure iron and carbon monoxide gas which escapes.
