Classification is defined as a method of separa ting mixtures of mineral particles into two or more products according to their settling v elocities in water, in air or in other fluids Since th e .
An ore is a special type of rock that contains a large enough amount of a particular mineral (usually a metal) to make it economically practical to extract that mineral from the surrounding rock .
It is also a residual mineral found in soils and sediments Cassiterite is more resistant to weathering than many other minerals, and that causes it to be concentrated in stream and shoreline sediments Although cassiterite is the most important ore of tin, it has ,
classification criterion (temperature) Lindgren's "types" included generalizations on depth of formation, occurrence, nature of ore zones, metal affiliations, ore minerals, gangue minerals, wall-rock alteration, textures and structures, and zoning
What is Spodumene? Spodumene is a pyroxene mineral that is typically found in lithium-rich pegmatitIt is usually associated with other lithium minerals such as lepidolite, eucryptite, and petaliteSpodumene has a chemical composition of LiAlSi 2 O 6 but small amounts of sodium sometimes substitute for lithium Throughout most of the 20th century, spodumene was the most important ore ,
Classification of ore deposits Classification of hydrothermal ore deposits is also achieved by classifying according to the temperature of formation, which roughly also correlates with particular mineralising fluids, mineral associations and structural styl

Apr 26, 2015· The mineral deposits formed under epigenetic condition, magmatic intrusion and hydrothermal depositional environments cause changes in mineralogy including formation of new minerals, chemical composition, color and texture of the ,
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 chemical and physical properti Scientists mostly use Strunz classification based in mineral chemistry and crystalography
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 (eg, halides, oxides, and sulfides)
The first genetic classification of ore deposits to win wide acceptance was that initially proposed by Waldemar Lindgren in 1906 and last revised by him in 1933 As ideas on the genesis of ores have undergone change in the thinking of geologists, the Lindgren classification has come under attack mainly by two groups
This mineral identification chart was created by Art Crossman as a college course project at Mansfield University in 1997 He did an outstanding job, organizing minerals on the chart in a systematic way - according to their properti
Hydrothermal mineral deposits are accumulations of valuable minerals which formed from hot waters circulating in Earth's crust through fractur They eventually create rich-metallic fluids concentrated in a selected volume of rock, which become supersaturated and then precipitate ore mineralsIn some occurrences, minerals can be extracted at a profit by mining
The more concentrated an ore mineral, the more valuable the mineral deposit For every mineral deposit there is a set of conditions, such as the level of concentration and the size of the deposit, that must be reached if the deposit is to be worked at a profit
Mineral resource classification is the classification of mineral resources based on an increasing level of geological knowledge and confidence Mineral deposits can be classified as: Mineral resources that are potentially valuable, and for which reasonable prospects exist for eventual economic extraction; Mineral reserves or Ore reserves are valuable and legally, economically, and technically .
A "mineral deposit" is a mineral occurrence of sufficient size and grade that it might, under the most favorable of circumstances, be considered to have economic potential An "ore deposit" is a mineral deposit that has been tested and is known to be of sufficient size, grade, and accessibility to be producible to yield a profit
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 chemical composition There are different grouping systems in ,
Jul 29, 2013· Geologists, are known to have more opinions than economists, so it should come as no surprise that the classification of mineral deposits, is an on-going hot topic The details will be debated until the sun cools, but the broad-brush classification of mineral deposits is generally understood Most .
Oct 22, 2017· Classification of ore deposits , deposits through the last century has required and still requires the examination of great numbers and many types of mineral districts and the recording of their similarities and differences Grouping together deposits with similar characteristics facilitates description, permits generalizations concerning .
An ore deposit is an accumulation of ore This is distinct from a mineral resource as defined by the mineral resource classification criteria An ore deposit is one occurrence of a particular ore type
