Mineral Mineral Classification of minerals: Since the middle of the 19th century, minerals have been classified on the basis of their stone composition. Under this scheme, they are divided into classes according to their dominant anion or anionic group (e.g., halides, oxides, and sulfides).
Mineral classification can be an organizational nightmare. With over 3,000 different types of minerals a system is needed to make sense of them all. Mineralogists group minerals into families based on their stone composition. There are different grouping systems in
Jun 25, 2013· The terminology used to define mineral assets is divided into 2 major groups: Resources and Reserves. Figure 1. Resources and Reserves: The relationships between the five groups of mineral asset reporting. Mineral Resources. A Resource is a concentration of a minerals that has a reasonable prospect of economic extraction.
the blocks are generally cuboidal, the vertical joints being very regular. The valuable minerals and metal-bearing deposits of the earth are found as— Lodes, the ordinary fissure vein running through various strata, and the gash vein, though wide at the surface, pinching out. Beds of ore
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
A variety of geological processes form ore bodies. The formation of the ore process is called the genesis of the ore. Classification of Ore Minerals. Ore Mineral deposits are categorized according to different criteria that have been established through the study of economic geology or mineral genesis. Typical are the classifications below.
The stone name for the substance of quartz is silica; and any mineral that is composed in part of silica is a silicate. In the Classification of Silicate Minerals and the study of minerals and rocks, silica is called an acid; in silicates, the substances other than silica are called bases, for example, lime, potash, and soda. When giving the full name of a silicate the names of these bases
The outer limits of P1-type resources are determined indirectly by extrapolating from similar known mineral deposits in the area. P1 is the main source from which C2 reserves can be increased. Category P2. Category P2 These resources represent possible mineral structures in known mineral deposits or ore-bearing regions.
Metallic minerals exhibit luster in their appearance and consist of metals in their stone composition. These minerals serve as a potential source of metal and can be extracted through mining. Examples of metallic minerals are Manganese, iron ore and bauxite are Metallic minerals and be divided into ferrous and non-ferrous metallic minerals.
Widely used types of minerals are gems, ores, precious stones etc. However these “mineral types” lack solid definition and they are often mixture of various minerals with different stone and physical properties. Scientists mostly use Strunz classification based in mineral chemistry and crystalography.

Quartz is one of the most common of all minerals that make up the continental crust. It is found in igneous, metamorphic, and sedimentary rocks. It is associated with many valuable ore deposits as well. Amethyst is a variety of quartz and owes its purple color to the presence of iron. It is composed of silicone dioxide SiO 2.: Rose Quartz is a variety of quartz and owes its pink color to the
In nature, minerals commonly have impurities present in very tiny amounts, usually 3% or less of the crystal by weight. These impurities don’t change the primary chemistry. Therefore, the mineral name, or species, doesn’t change. They do, however, change some of the mineral ’s characteristics, so we use a sub-classification called a variety.
The principal gold minerals that affect the processing of gold ores are native gold, electrum, Au-Ag tellurides, aurostibite, maldonite, and auricupride. In addition, submicroscopic (solid solution) gold, principally in arsenopyrite and pyrite, is also important. The process mineralogy of gold: The classification of ore types.

A mineral is a naturally-occurring substance formed through geological processes that has a characteristic stone composition, a highly ordered atomic structure and specific physical properties. A rock is a naturally occurring aggregate of minerals and/or mineraloids.Rocks do not have a definite stone composition.
The Berzelian mineral classification system was named in honor of the Swedish chemist and mineralogist Jons Jakob Berzelius (1779-1848). (Cu2S). Melanterite is an iron ore which is formed by the oxidation and hydrothermal alteration of pyrite (FeS2) or other iron sulfide minerals. This species is yellow green to deep green due to the
Classification of Ore Deposits. Classification of Ore Deposits Some minerals are “persistent” and others of limited temperature range By collecting the data of mineral association sequence of deposition and stability range of the component parts of a deposit it will be possible to ascertain
