The branch of industry concerned with the search for, and extraction of, minerals from the Earth is called mining. The site in which minerals are found is usually called a mine—two exceptions are oil wells and rock quarries. The kinds of minerals dug from the Earth vary widely. They include the ores of iron, aluminum, chromium, tungsten, gold ...

Crushing and grinding are the two primary comminution processes. Crushing is normally carried out on "run-of-mine" ore, while grinding (normally carried out after crushing) may be conducted on dry or slurried material. In comminution, the size reduction of particles is done by three types of forces: compression, impact and attrition.
