Extraction of Metals | Good Science

Carbon Reduction of Metals. Metals with an intermediate reactivity, such as iron and zinc, which form part of minerals, need to be chemically extracted from ore.; This is done by a process called carbon reduction. Carbon reduction is a type of displacement (redox) reaction, where carbon is used to displace the metal from the mineral compound.; The crushed ore is mixed with carbon and heated to
