More Information
Metallurgy is the science of extracting metals, largely important for industries. Ores are minerals from which metals can profitably be extracted. Carbon, in the form of coke, is used as a reducing agent in the extraction of iron.
Tips
A common mistake is confusing ores with minerals; remember ores are economically viable for metal extraction.
