Hydrothermal mineral deposits are accumulations of valuable minerals which formed from hot waters circulating in Earth''s crust through fractures. They eventually create richmetallic fluids concentrated in a selected volume of rock, which become supersaturated and then precipitate ore some occurrences, minerals can be extracted at a profit by mining.

Metallic Minerals is composed of metals in their original form, whereas no metals are found in nonmetallic minerals. Minerals possess a definite chemical structure, and their identification is based on their physical properties. The place where minerals are found is called an ore. Ores are the concentration of any mineral with other elements, found in a particular area, in the form of rocks ...

combined with sulfur in sulfide minerals, so that a base metal deposit is not only polyelemental, it is polymineralic as well. The more common basemetal sulfide minerals are: • chalcopyrite (% Cu) • bornite (% Cu) • sphalerite (67% Zn) • galena (% Pb). Thus, in a Cu–Zn deposit the copper may be contained in chalcopyrite and/or bornite, and the zinc in sphalerite. Other ...

Mining and Mineral Processing. Metal deposits are mined in a variety of different ways depending on their depth, shape, size, and grade. Relatively large deposits that are quite close to the surface and somewhat regular in shape are mined using openpit mine methods (Figure ). Creating a giant hole in the ground is generally cheaper than making an underground mine, but it is also less ...
