Ore minerals. Two factors determine whether a given mineral is suitable to be an ore mineral. The first is the ease with which a mineral can be separated from the gangue and concentrated for smelting. Concentrating processes, which are based on the physical properties of the mineral, include magnetic separation, gravity separation, and flotation.

Mineral: The inorganic element or compound, which occurs naturally in the earth's crust is called mineral. for example, copper pyrites (CuFeS 2), cuprite (Cu 2 O), etc. are the minerals of copper. Ore: The mineral from which a metal can be extracted profitably and conveniently is called an ore. For example, bauxite (Al 2 O 3.2H 2 O) and clay (Al 2 O 3.2SiO …

If the internal atomic arrangement is lacking, then it is an amorphous substance. A rock is generally composed of various minerals and if the rock contains valuable minerals frOm which metals can be extracted at a profit, it is called an 'ore'. The unwanted mineral in an ore is called gangue (i.e., generally rock forming minerals). For ...

The ore is generally associated with Earthy impurities like Sand, rocks, and limestone Known as Gangue or Matrix. A substance added to ore to remove the impurities is called flux. The combination of gangue with flux in ores forms a fusible material called Slag. The concentration of ore is the process of eliminating gangue from the ore.

Hydrothermal Deposit: A mineral deposit formed by precipitation of ore and gangue minerals in fractures, faults, breccia openings, or other spaces, by replacement or open-space filling, from aqueous fluids ranging in temperature from 50º to 700ºC but generally below 400ºC, and ranging in pressure from 1 to 3 kilobars. The fluids are of ...

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 ...

Density separation is widely used to pre-concentrate ore minerals and reject unwanted gangue prior to the main processing stage of an ore (e.g. flotation). For base metal sulfide ores, dense medium separation (DMS) is used to separate the sulfide minerals, which are relatively dense, from the less dense silicate gangue minerals.

Ore and gangue minerals react internally, or with their environment, at widely ranging rates, ranging from the almost inert pyrite, arsenopyrite, well-crystallised quartz, and tourmaline to the notoriously fickle copper/iron and copper/silver sulfides.

Overburden is typically removed without being processed. The economically useless material within an ore body is called gangue. Gangue is distinct from overburden in that it surrounds or is mixed with the valuable minerals. The primary reason for mineral processing is to separate and concentrate the valuable minerals from the gangue.

A gangue mineral, on the other hand, is a mineral that has no economic value and is generally found alongside the ore mineral. Gangue minerals are typically regarded as undesirable or waste minerals in mining operations since they contain no useful elements or compounds. Step 3.

Gangue, unwanted minerals in ore, is separated through processes like froth flotation, gravity concentration, or magnetic methods. Mineral processing involves liberation and concentration. The remaining gangue, termed tailings, is potentially harmful and abundant, especially in lower grade deposits.
