Many sources mention coltan's importance in the production of mobile phonesbut tantalum capacitors are used in almost every kind of electronic device. Niobium and tantalum have a wide range of uses, including refractive lenses for glasses, cameras, phones and printers.
Mineral resources[ edit ] A 'Mineral Resource' is a concentration or occurrence of material of intrinsic economic interest in or on the earth's crust in such form, quality and quantity that there are reasonable prospects for eventual economic extraction.
Mineral Resources are further sub-divided, in order of increasing geological confidence, into inferred, Indicated and measured Categories. Inferred Mineral Resource is the part of a mineral resource for which tonnage, grade and mineral content can be estimated with a low level of confidence.
It is inferred from geological evidence and assumed but not verified geological or grade continuity.
It is based on information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes which may be of limited or uncertain quality and reliability.
Indicated resources are simply economic mineral occurrences that have been sampled from locations such as outcrops, trenches, pits and drillholes to a point where an estimate has been made, at a reasonable level of confidence, of their contained metal, grade, tonnage, shape, densities, physical characteristics.
Measured resources are indicated resources that have undergone enough further sampling that a 'competent person' defined by the norms of the relevant mining code; usually a geologist has declared them to be an acceptable estimate, at a high degree of confidence, of the grade, tonnage, shape, densities, physical characteristics and mineral content of the mineral occurrence.
Mineral reserves and ore reserves[ edit ] Mineral reserves are resources known to be economically feasible for extraction.
Reserves are either Probable Reserves or Proved Reserves. A Probable Ore Reserve is the part of indicated, and in some circumstances, measured mineral resources that can be mined in an economically viable fashion.
It includes diluting material and allowances for losses which may occur when the material is mined. A Probable Ore Reserve has a lower level of confidence than a Proved Ore Reserve but is of sufficient quality to serve as the basis for decision on the development of deposit.
A Proved Ore Reserve is the part of Measured resources that can be mined in an economically viable fashion.
It includes diluting materials and allowances for losses which occur when the material is mined. A Proved Ore Reserve represents the highest confidence category of reserve estimate. The style of mineralization or other factors could mean that Proved Ore Reserves are not achievable in some deposits.
Generally the conversion of resources into reserves requires the application of various modifying factors, including: Essentially, once a deposit is elevated to reserve status, it is an economic entity and an asset upon which loans and equity can be drawn—generally to pay for its extraction at hopefully a profit; economic factors.The European Technology Platform on Sustainable Mineral Resources (ETP SMR) Mission is to develop long-term European Minerals Industries Research and Innovation agendas and roadmaps for action at EU and national level.
