Expand/collapse global location. 12.3: Ore Genesis. Page ID. The various theories of ore genesis explain how the various types of mineral deposits form within the Earth's crust. Ore genesis theories are dependent on the mineral or commodity. Ore genesis theories generally involve three components: source, transport or conduit, and trap.
In different ore sources, the indicative elements were different and the concentration of elements also had an impact on the classification (Figure 5b–f). The ability to correlate element concentration with its contribution to classification was a significant advantage of SHAP [ 66 ].

3. INTRODUCTION The purpose of any classification is to group similar objects into classes or sets either for convenience, organization, or access, as in a collection,a library, or a computer data base, or for the purpose of learning more about the items being classified . The study of ore deposits through the last century has required …
mineral classification. minerals are classified or grouped into families according to their chemical composition. native elements. consists of one single element; gold, graphite etc. halides. consists of a metal + halogen (CL, F, Br); fluorite. carbonates. consists of a metal + carbonate group (CO3); calcite, dolomite.
In accord with Nickel [ 1 ], a mineral species can be defined as follows: a solid chemical substance formed as a result of geological processes. Disregarding the geological processes, this definition implies that a mineral can be crystalline, quasi-crystalline, or even non-crystalline (amorphous and metamict).
Similarly, the term mineral species has been introduced to include natural crystals with similar structural and chemical properties. As an illustration, consider how this term can …
The chemical formula of sphalerite is (Zn,Fe)S. It is a zinc sulfide containing variable amounts of iron that substitutes for zinc in the mineral lattice. The iron content is normally less than 25% by weight. The …
Classification. Just as sulfur and chromium form the anion groups (SO4)2- and (CrO4)2-, the ions of molybdenum (Mo) and tungsten (W) bond with oxygen atoms to create the anion groups (MoO4)2- and (WO4)2-. These anion groups then bond with metal cations to form the minerals of the. molybdate and tungstate classes.

2.2.4 During 20th Century. The world's most regarded economic geologist, Waldemar Lindgren (1860 – 1939) (Fig. 2.3b) (one of the founders of modern economic geology) in 1911, wrote a book 'Mineral Deposits'. He classified mineral deposits into two types such as Pyrometasomatic and Hydrothermal Deposits.

Chemical Composition. Nearly all (98.5%) of Earth's crust is made up of only eight elements – oxygen, silicon, aluminum, iron, calcium, sodium, potassium, and magnesium – and these are the elements that make up most minerals. All minerals have a specific chemical composition. The mineral silver is made up of only silver atoms and diamond ...
Similarly, the term mineral species has been introduced to include natural crystals with similar structural and chemical properties. As an illustration, consider how this term can be used with the garnet mineral group. Garnets have a common formula R 1 3 R 2 2 (SiO 4) 3 (R 1 and R 2 representing two different cations). They crystallize in cubic ...
Except for the native element class, the chemical basis for classifying minerals is the anion, the negatively charged ion that usually shows up at the end of the chemical formula of the mineral. For example, the sulfides are based on the sufur ion, S 2–. Pyrite, for example, FeS 2, is a sulfide mineral.
Introduction to Ore Deposits: Minerals form chief source of all the industrial metals and non-metals. The commonly used metals like aluminum, copper, iron, lead, zinc etc. are all manufactured using minerals as raw materials. Similarly non-metals like glass and refractories are also made from minerals. Minerals are also source of energy.
Composition: Iron ore is primarily composed of iron, usually in the form of iron oxides such as hematite (Fe2O3), magnetite (Fe3O4), or goethite (FeO (OH)). It may also contain other elements or minerals as impurities, such as silica, alumina, phosphorus, sulfur, and trace elements. Physical properties: Iron ore is usually hard, dense, and heavy.
Sphalerite mineral is in group of Sulfide mineral that is formula ( (Zn, Fe)S).It is the principal ore of zinc. Pure sphalerite is colorless and rare. Normally, iron is present, causing the color to vary from pale greenish yellow to brown and black with increasing iron content. When iron content is high it is an opaque black variety, marmatite.
