Extraction of Metals | Good Science
Metals with an intermediate reactivity, such as iron and zinc, are chemically extracted from minerals by a process known as carbon reduction. Carbon reduction is a type of redox reaction, where carbon is used to displace a metal from a compound. The crushed ore is mixed with carbon and limestone, then heated to a molten state (smelted) in a
