This extraction experiment consists of two competition reactions. A metal oxide is reacted with charcoal. If the charcoal (carbon) is more reactive it will remove the oxygen from the metal oxide and leave a trace of metal in the reaction vessel. Start with an oxide of lead, then observe what happens to an oxide of copper.

An ore is usually a compound of the metal mixed with impurities. When the metal is dug up, a method must be used to separate the metal from the rest of the ore. This is called extracting the metal. The method of extraction depends on how reactive the metal is. The more reactive the metal, the more difficult it is to extract from its compound.

Example: Extracting Lead from Cerussite. Mining : digging or blasting to obtain the lead ore from the surrounding rock; Crushing : mined lead ore is crushed into very small pieces ; Grinding : crushed lead ore is ground into a powder; Concentrating by flotation (also known as froth flotation or as ore flotation).

Silver is rarely found in its native state, and is generally found in alloyed state with lead or in the form of silver compounds. The Mesopotamian civilization is credited with the invention/discovery of extracting silver through the process of "cupellation" from the leadsilver ores at around 2500 3000 BCE.
