Wrought iron is obtained by heating cast iron in a furnace with iron ore, haematite. During this process, sulphur and carbon are oxidized and then removed as their gaseous oxides. Phosphorus and silicon(IV)oxide present in the process are oxidized and also removed from the semi-molten mass of iron as slag. This metal is soft and malleable but very tough.

Sep 26, 2019 · Metallurgy is the study of ore mining and extraction of valuable metals. That is why the science of metallurgy tends to focus on the manufacture of alloys, in which metals are combined together or with non-metals. Steel and cast irons are examples of iron- carbon alloys. Aluminum, copper, iron, magnesium, and zinc are the metals that are used most, usually in their alloy forms.
