Ore vs Gangue

As nouns the difference between ore and gangue is that ore is rock that contains utilitarian materials; primarily a rock containing metals or gems which -- at the time of the rock's evaluation and proposal for extraction -- are able to be separated from its neighboring minerals and processed at a cost that does not exceed those materials' present-day economic values while gangue is....

Gangue

In mining, gangue (/ ɡ æ ŋ /) is the commercially worthless material that surrounds, or is closely mixed with, a wanted mineral in an ore depositIt is thus distinct from overburden, which is the waste rock or materials overlying an ore or mineral body that are displaced during mining without being processed, and from tailings, which is rock already stripped of valuable minerals; a ....

Froth Flotation of Iron Ores

strength in iron ore flotation pulp The presence of calcium and magnesium is particularly detrimental to kaolinite removal from iron ore[32] For dispersant-kaolinite interactions, it was found that sodium silicate, a standard dispersant widely used in iron ore flotation for silicate gangue minerals, is inadequate to disperse kaolinite[35] A...

Iron ore

Increasing iron ore demand, coupled with the depletion of high-grade hematite ores in the United States, after World War II led to development of lower-grade iron ore sources, principally the utilization of magnetite and taconite Iron-ore mining methods vary by the type of ore being mined...

Gangue Mineral

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 913 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...

Feb 13, 2018· Ores are those minerals from which valuable metal can be extracted Gangue is the impurities in ore which has to be separated in order to obtain desired metal from its ore...

STRATEGIES FOR PROCESSING LOW

For example, many ores contain iron oxide in a nonmagnetic form and are so fine-grained that it is uneconomical to grind them to a fine enough size to separate the iron oxides from the gangue Exploitation of these iron minerals needs to take a different approach, using fewer process steps than are required for conventional ironmaking...

Different Types of Iron Ore

Hematite is the most important iron ore The iron content of the pure minerals is as follows: Ankerite is a carbonate of lime, magnesia, manganese, and iron It is of valuable composition, carries only 14 or 15% of iron, and is used more for its lime and magnesia as a flux than for its iron-content...
