United Nations Framework Classification of Mineral

 · United Nations Framework Classification (UNFC) of Mineral Reserves/Resources consists of a three dimensional system with the following three axes Geological assessment Feasibility assessment and Economic viability. The process of geological assessment is generally conducted in stages of increasing details (Fig 1)

Classification of mineral depositsOnline Mining Exam

Classification of mineral deposits Mineral is a solid naturally occurring inorganic substance. Mineral is having definite chemical composition. Mineral Resource and Mineral reserve both are quite a different thing. Many of the candidates are confused in the classification of mineral deposit.

Mineral Deposits • GeoLearning • Department of Earth

Mineral deposits (metallic non-metallic and combustible materials) constitute major raw materials for industrial development today and the demand for these raw materials is ever increasing. Mineral deposits include several different types related to magmatic hydrothermal sedimentary and metamorphic processes. Classification of deposits

Classification of mineral deposits into types using

In order to determine whether it is desirable to quantify mineral-deposit models further a test of the ability of a probabilistic neural network to classify deposits into types based on mineralogy was conducted. Presence or absence of ore and alteration mineralogy in well-typed deposits were used to train the network. To reduce the number of minerals considered the analyzed data were

Geological ore depositsThe Australian Museum

Geologists classify mineral deposits in many different ways according to the commodity being mined. tectonic setting in which the deposit occurs. geological setting of the mineral deposit. genetic model for the origin of the ore deposit. The most commonly used scheme is the genetic classification scheme.

Classification of mineral deposits into types using

Across all deposit types 88 of deposits in the validation dataset were correctly classed. Misclassifications were most common if a deposit was characterized by only a few minerals e.g. pyrite chalcopyrite and sphalerite. The success rate jumped to 98 correctly classed deposits when just two rock types were added.

Classification Of Mineral Deposits 6nq83wr70pnw

Classification of Mineral Deposits Introduction In order to more readily study mineral deposits and explore for them more effectively it is helpful to first subdivide them into categories. This subdivision or classification can be based on a number of criteria such as minerals or metals contained the shape or size of the deposit host

Classification of Mineral Resources and Reserves Geology

 · Classification of Mineral Resources and Reserves. In the early days of mining there were no standards for the reporting of mineral assets. Companies or individuals would usually take grades observed in drill core and using some clever geometry extrapolate them to define a deposit. This usually involved a large amount of guesswork and errors

Sedimentary deposits of iron oxides and hydrous aluminum oxide are of this type. In other cases the ore deposits (or more precisely ore minerals) may be present in an enclosing rock
