Without carbon there would be no cast iron or steel, as it has been the reducing agent used to liberate metallic iron from its ores since the earliest times. A few tenths of a percent difference in carbon content can have a dramatic effect on the mechanical properties of iron and steel, so its accurate measurement is critical to ferrous metallurgy.

10/7/2019· Carbon reduction is a process from which we can extract a metal from a fused metal oxide using carbon. Here, carbon acts as a reducing agent. In this process, we can get free metal out of metal oxide in the ore. Further, this method is suitable for metals such
Reduction of Metal Oxide to Metal
The Oxides of Metals like Zn, Fe, Cu, Ni, Sn and Pb are usually reduced by using carbon as reducing agent. In this process, coke is mixed with roasted ore and heated to a high temperature in a furnace. Coke reduces the metal oxides into free metal. For

The Ellingham Diagram | 2011-04-04 | Industrial Heating
The severe negative slope of this carbon reaction results in an increasingly more powerful reducing agent as temperature increases. For example, at 1500°C (2732°F), the carbon reaction crosses under that for silicon dioxide (SiO 2 ), resulting in the potential ability to reduce the highly stable compound of SiO 2 to silicon under oxygen-starved conditions.
Ferrous metallurgy — Wikipedia Republished // WIKI 2
Ferrous metallurgy is the metallurgy of iron and its alloys. It began far back in prehistory. The earliest surviving iron artifacts, from the 4th millennium BC in Egypt, were made from meteoritic iron-nickel. It is not known when or where the smelting of iron from ores began, but by the end of the 2nd millennium BC iron was being produced from iron ores from Sub-Saharan Africa to China. The
