Gangue Geology Wiki FANDOM powered by Wikia
In mining gangue 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 and it is a necessary and often significant aspect of mining can be a complicated process depending on the nature of the minerals involved.

If the gangue mineral in an iron ore is predominantly quartz reverse flotation is usually used in the cleaning stage to improve the concentrate grade. Figure 9.13 presents a typical flow sheet for processing an oxidized iron ore containing about 30 Fe using a combination of SLon magnetite separators and reverse flotation. The ore is mainly composed of magnetite hematite martite and quartz.
More MessageIn Mining what is Gangue (with picture)
Gangue is the substance that must be extracted along with desired minerals or ores due to their close association. These materials are typically removed along with the target minerals or ores and must then be separated out. Gangue may then be dumped as tailings. In some cases there may be additional uses for the materials present in tailings.

The removal of the gangue from the ore is called ore dressing or concentration of the ore. It may then be dumped as tailings. Mining companies take into consideration the costs that they will incur for separating the economic fraction from useless gangue and only then decide if a mining operation will be economically viable.
