Why is calcium used as a reducing agent? - Answers
Reducing agents are either an element or a compound that are used in the metallurgy. For different metals, different reducing agents are used. So, they are not common for all metals. Carbon is a

Extraction of Metals from Concentrated Ore: Reduction of …
Extraction of Metals Now we already saw how the ore of a metal is concentrated to remove impurities known as gangue. After concentration of ores, we must now extract metal from in it. This step will give us metal in its pure form i.e. the native form of metal. First

hydrogen could replace natural gas, gasoline, etc., and could serve as a reducing agent in metallurgy, chemical processing, refining, etc. It could also be used to convert trash into methane and ethylene. Forms Quite apart from isotopes, it has been shown that
Timeline of Ferrous Metallurgy Development - Ferrous …
Early iron smelting used charcoal as both the reducing agent and heat source. By the 18th century, the availability of wood for making charcoal was limiting the expansion of iron production. In the early 17th century, it was attempted produce pig iron using coal in the place of charcoal, but the product was refused because of its bad quality due to sulfur.
