Metals Found in Rocks | Facts about Minerals | DK Find Out
The rock or mineral that holds the metal is called an ore. An ore is heated with chemicals until it melts and the pure metal separates out as a liquid. The liquid then cools and hardens. A few metals, such as gold, silver, and copper can be found in pure form as metal elements. Nuggets or flakes of these metals can be taken straight from rock, but this is uncommon. Metals are used .

Extracting a metal from its ore
Those minerals that contain sufficient metal to be of practical and economic use are called ores. 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, .
