Classification of Mineral Deposits - Earth Sci

These elements are deposited to form the ore and gangue minerals in response to a change in the solution, very often a sharp decrease in temperature. an example of this process would be if you dissolved as much table salt as possible in boiling water. If you then cool the solution in the fridge, much of the salt will precipitate or come out of solution.

Skarn - Wikipedia

Etymology. Skarn is an old Swedish mining term originally used to describe a type of silicate gangue, or waste rock, associated with iron-ore bearing sulfide deposits apparently replacing Palaeoproterozoic age limestones in Sweden's Persberg mining district.. Petrology. Skarns are composed of calcium-iron-magnesium-manganese-aluminum silicate minerals. Skarn deposits are economically valuable ...

Difference between mineral and ore gangue and

This classification is very important in mineral processing to determine the strategy to remove gangue minerals. Sometimes a gangue mineral may become a valuable mineral, as gangue definition is related to economic value, and the price of mining products varies and governs by supply and demand. Therefore a gangue mineral becomes a valuable mineral if its price increase enough to allow its ...

What is the gangue in chemistry?

In mining, gangue (/gæŋ/) is the commercially worthless material that surrounds, or is closely mixed with, a wanted mineral in an ore deposit. The separation of mineral from gangue is known as mineral processing, mineral dressing, or ore dressing. What is ore and gangue? Mineral: The naturally occurring compounds of elements are known as Mineral.

Introduction to Mineral Processing or Beneficiation

In order to separate the minerals from gangue (the waste minerals), it is necessary to crush and grind the rock to unlock, or liberate, valuable minerals so that they are partially or fully exposed. This process of size reduction is called comminution. The crushing and grinding process will produce a range of particles with varying degrees of liberation (Figure 2). Any particles that exceed a ...

Most of the useful minerals and gangue minerals are closely combined. Therefore, before high-efficiency separation, it is necessary to solve the problem of dissociation of the target minerals and gangue minerals. After the minerals reach monomer dissociation, qualified products can be obtained through separation operation. At present, grinding classification is a common and effective way to ...

11. Hydrothermal Alteration - USGS

Relations among Alteration, Gangue, and Ore. Ore is traditionally defined as a valuable mineral or chemical commodity that can be extracted at a profit. In VMS deposits, ore generally consists of sulfide or sulfosalt minerals that contain Cu, Pb, Zn, Ag, and (or) Au. Gangue is defined as any noneconomic mineral deposited together with ore; in
