An ore (or ore deposit) is a volume of rock containing valuable minerals that occur at sufficiently high concentrations for profitable mining, transportation, milling, and processing.If the body of mineralization is of too low a grade or tonnage, or the desired mineral is technically too difficult to extract, then the deposit is not called an ore.

Because sulfur is a common component of these fluids, the ore minerals found in hydrothermal deposits are called sulfides, e.g. copper is mined from copper sulfide (CuS), lead is mined from a lead sulfide mineral called galena (PbS), zinc is mined from a zinc sulfide called sphalerite (ZnS): these minerals all come from hydrothermal deposits.

Fool's Gold can be one of three minerals. The most common mineral mistaken for gold is pyrite. Chalcopyrite may also appear gold-like, and weathered mica can mimic gold as well. Compared to actual gold, these minerals will flake, powder, or crumble when poked with a metal point, whereas gold will gouge or indent like soft lead. In addition, actual gold will leave a golden yellow streak …

Metals are mixed with other metals, which are then called alloys. For example, tin breaks easily, while lead is a soft metal. However, together, tin and lead make a very tough and strong alloy which is called pewter. Only a few metals occur naturally in their pure state. Most metals are locked up within minerals and rocks known as ores.
