Classification of Mineral Deposits introduction hydrothermal deposits magmatic deposits ., although we started out with a physically descriptive classification, we end up with a classification which also coincides with what we perceive to be unique genetic processes. . Magmatic deposits are syngenetic in that the ore minerals crystallize .
Mineral - Mineral - Classification of minerals: Since the middle of the 19th century, minerals have been classified on the basis of their chemical composition. Under this scheme, they are divided into classes according to their dominant anion or anionic group (e.g., halides, oxides, and sulfides).

Tin Ore Classification One of the most recent tin projects in Bolivia involves the classification into four ranges:1. -1,800 micron +850 micron2. - 850 micron +212 micron3. -212 micron +45 micron4. -45 micron +30 micronTo obtain this classification after the primary mill it was defined in basic e
In Mineral Processing, the SPIRAL Classifier on the other hand is rotated through the ore. It doesn't lift out of the slurry but is revolved through it. The direction of rotation causes the slurry to be pulled up the inclined bed of the classifier in much the same manner as the rakes do.
Hydrothermal mineral deposits are accumulations of valuable minerals which formed from hot waters circulating in Earth's crust through fractures. They eventually create rich-metallic fluids concentrated in a selected volume of rock, which become supersaturated and then precipitate ore minerals.In some occurrences, minerals can be extracted at a profit by mining.
Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy.

This is an area where improved and higher resolution ore classification data would be of great potential benefit. The broader need for textural classification schemes. The increased prevalence of goethite in ore from Australian mines highlights the growing need for textural classification to account for differences between goethite types.
Strunz Classification of mineral species. Definition "Prof Hugo Strunz introduced a chemical-structural classification of the entire domain of minerals (Mineralogische Tabellen, 1941), followed by A.S.Povarennykh with a modified classification (1966 in Russian, 1972 in English).The chemical-structural classification of H. Strunz has gone through a number of editions, and is currently in the .
Hematite is sometimes found in vein-like deposits which are not usually large enough to be important. Such ore-bodies have been found near Kitchener, B.C. and in the Matachewan area, Ontario. Deposits of considerable size have been found at the contacts of igneous intrusions, generally basic, with crystalline limestone, dolomite, and limey shale; the ore is usually of the specular variety, and .

In another common method of classification, ore minerals are divided into hypogene (also termed primary) deposits and supergene (also known as secondary) deposits. The secondary deposits are formed as alteration products of primary deposits through weathering and related processes. An ore deposit may be either of igneous or of sedimentary origin.
