How Are Minerals Formed?
Minerals grouped together form rocks; the combination of minerals determines the type of rock formed. Since minerals are pure, they can all be written as a single chemical formula. A mineral can also contain some impurities and still retain its name, as long as the majority of the solid is a single mineral.

Classification of Minerals
Metallic minerals. These are minerals that contain one or more metals. Iron, copper, gold, bauxite, and manganese are examples of metallic minerals that occur as mineral deposits and are great conductors of heat and electricity. They are malleable and ductile, allowing them to be easily hammered into thin sheets or stretched into wires to form new things.

2.4: Mineral Basics
Standard names for luster include metallic, glassy, pearly, silky, greasy, and dull. It is often useful to first determine if a mineral has a metallic luster. A metallic luster means shiny like polished metal. For example cleaned polished pieces of chrome, steel, titanium, copper, and brass all exhibit metallic luster as do many other minerals.
