electrical conductivity in typical minerals is usually due to some “impurities” such as ferric iron and hydrogen (Fig. The electrical conductivity in iron-bearing minerals can still be “intrinsic”, i.e., conductivity could occur by the formation of a pair of electrons and holes through reaction (5).

Other articles where Ore mineral is discussed: mineral deposit: are commonly referred to as ore minerals. Ore minerals tend to be concentrated in small, localized rock masses that form as a result of special geologic processes, and such local concentrations are called mineral deposits.
Mineral deposits are what prospectors seek. The terms ore mineral and mineral deposit were originally. Some band-gap semiconductor minerals are listed in Table 6.
Semiconducting ore minerals are the subject of a book by Shuey (). Impurities in semiconductors Medium- and large-band-gap semiconductors do not conduct electricity at room temperature when pure, since the ambient excitation is insufficient to bridge the band-gap.

Polished ore minerals exhibit a range of colours and textures in reflected light (they are also commonly studied using scanning electron microscopes and electron microprobe). Metalliferous ores are studied under the microscope to understand their formation, and because of their commercial and strategic value.
Ore is natural rock or sediment that contains desirable minerals, typically metals, that can be extracted from it. Ore is extracted from the earth through mining and refined, often via smelting, to extract the valuable element or elements. The grade of ore refers to the concentration of the desired material it contains.
The value of the metal an ore contains must be weighed against the cost. Minerals that contain iron are called ferrous minerals. Example of ferrous minerals is Chromites, Iron ore, and manganese. Minerals that do not contain iron are called non- ferrous minerals.
Examples of nonferrous minerals is lead, silver, gold, and copper. There is a group of chemical elements which when melted do not generate a new product.
