A mineral is a naturally occurring chemical compound, usually of crystalline form and abiogenic in origin (not produced by life processes). A mineral has one specific chemical composition, whereas a rock can be an aggregate of different minerals or mineraloids. The study of minerals is called mineralogy.
Copper (CU) is a mineral which can easily be taken in excess, although it is essential for normal functioning. The average adult has 60 - 110 mg of copper in the body. The liver controls copper storage and any excess is excreted via the bile, though if your copper intake increases so does the amount that you store.
