Extracting a metal from its ore chymist

Metals are usually extracted from ores using a combination of heating and reduction with carbon in the form of charcoal or coke. Not all metals can be extracted from their ores in this manner and may need to be extracted by a process called electrolysis. Metals with low chemical activity, such a gold and silver are normally found in their pure state.

Carbon in Metal Extraction Worksheet EdPlace

Metals are extracted from their ores. An ore is a mineral, which is a metal compound that contains enough quantity of the metal to be extracted. The picture shows extraction of iron ore in a mine. Carbon is used to extract metals from their ores. This method involves reduction. Reduction means gain of electrons and loss of oxygen (see diagram).
