concepts of minerals When we spoke of Mineral Deposits, there is a series of concepts that have a great importance, or in the geologic-geoqui'micos aspects, or the economic ones. Most important they are the following ones: Mena: It is the mineral whose operation presents/displays interest. In general, it is a term that talks about metallic minerals and that it designates to the mineral of which the chemical element of interest is extracted (Cu of the chalcopyrite, Hg of the cinnabar, Sn of the cassiterite, between many possible examples). In this case of metallic minerals, a treatment of the mena is required, that in general includes/understands two stages: the mineralúrgico treatment and the metallurgical one (to see more down). Gangue: It includes/understands to the minerals that accompany the mena, but which they do not present/display mining interest at the moment of the operation. Frequent examples in metallic mining are the quartz and the calcite. It agrees to stand out that mineral considered as gangue at certain moments has transformed into menas when knowing itself some new application for such Reserves: Amount (mass or volume) of mineral susceptible to be operated. It depends on a great number of factors: average law, law of cut (to see more down), and of the specificationses, environmental and of market existing at the moment for carrying out the operation. It is complemented with the concept of Resource, that is the total amount of existing mineral in the zone, including which its low concentration or law could not be operated by.

It depends on to great to number of factors: average law, law of cut (to see dwells down), and of the specificationses, for environmental and of market existing AT the moment carrying out the operation. It is complemented with the concept of Resource, that is the total amount of existing mineral in the zone, including which its low concentration or law could not be operated by. To see dwells details pressing here. Law of cut or cut-off: It is the harassing concentration that must have an element in a deposit to be operateable, that is to say, the concentration that does possible to pay the costs of its extraction, treatment and commercialization. It is a technological factor that depend as well on other factors, that can not have anything to do with the nature of the deposit, as for example they can be his proximity or distance to transport routes, advances in the extraction, etc. Factor of concentration: It is the enrichment degree that it has to present/display an element with respect to his normal concentration so that it is operateable, is to say: Origin of the Mineral Deposits The origin of the mineral deposits can so be varied as they are it the geologic processes, and practically any geologic process can give origin to mineral deposits. In a more restrictive study, it is necessary to consider two great groups of deposits: 1.-Those of minerals, either are metalists or industrialists, which usually they have his origin in local phenomena that affect to a rock or set of, 2.-Those of industrial rocks, that correspond to concrete areas of that rock which they present/display local characteristics that favor their mining operation.
