Extraction of Metals: Ores and Minerals - Chemistry

Extraction of metals. The process of extracting metal ores buried deep underground is called Mining. The metal ores are found in the earth’s crust in varying abundance. The extraction of metals from ores is what allows us to use the minerals in the ground! The ores are very different from the finished metals that we see in buildings and bridges.

Extraction and Reduction of Metals – Assignment Example

Metals are usually obtained from their minerals, by a process called reduction. There are several most common occurring metals found in the earths crust. Most of these are found in the form of minerals or ores. The unreactive metals gold and platinum, and the more reactive metals copper, silver and mercury are found as pure metals in the earths crust.
