Gangue minerals are not considered ores because they do not contain valuable minerals that can be extracted profitably. Ores, on the other hand, contain valuable minerals in high enough concentrations to be economically recovered. Gangue is typically separated from the ore during the mineral processing stage.

What is the relationship between mineral ore and gangue?
Mineral ore is the valuable material that can be extracted and processed for its useful properties, while gangue is the unwanted material that is typically separated from the ore during the extraction process. Gangue does not have any economic value and is usually discarded as waste material. The relationship between mineral ore and gangue is that they are often found together in the same rock or ore deposit, with the goal of separating the valuable ore from the gangue to extract the desired minerals.
What waste rock must be removed before a mineral can be used?
Overburden and gangue are the waste rocks that must be removed before a mineral can be used. Overburden refers to the unconsolidated material above an ore deposit, while gangue is the unwanted rock in an ore deposit that has to be separated during processing.
What two problems can result from removing waste material from ores?
It can be expensive and harmful to the environment.yes it can be harmful yet it can cause dormant toxins in the ore to become active.Not to mention that the more you mine the ore the actual gangue becomes higher than the actual value of the ore itself, therefore ridding it of the classification "ore"(gangue: the commercially valueless material in which ore is found.)(bold = edited by Ethan Urban)
Waste rock that must be removed before a mineral can be used?
The waste rock that must be removed before a mineral can be used is known as ore. The process of removing waste rock to extract valuable minerals is called mining. This waste rock is separated from the ore during the mining process.
What is self fluxing?
Generally the Iron ore contains Silica as main gangue material. To remove silica in the form of Slag, we add CaO or MgO as flux material. But if the ore itself have the higher content of CaO or MgO along with Silica, the ore will be SELF FLUXED and no need to add external Flux. So, the self fluxing is an advantage in the case of iron ores having CaO or MgO in gangue.

What is the waste material that must be separated from an ore?
The waste material that must be separated from an ore is known as gangue. Gangue is the material that does not contain any valuable minerals and is typically removed during the process of ore extraction and purification.
What is a gangue?
Gangue is the waste material that surrounds and is mixed in with valuable minerals in an ore deposit. It does not have any commercial value and is usually removed during the process of extracting the valuable minerals.
What is the name of a process by which low-grade ore is separated from gangue?
refining
What are two conditions which could occur to cause gangue to br reclassified as an ore?
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 gangue from minerals can be a major obstacle. The ore may also be crushed to a fine grain.
What waste rock must be removed before a mineral can be used?
Overburden and gangue are the waste rocks that must be removed before a mineral can be used. Overburden refers to the unconsolidated material above an ore deposit, while gangue is the unwanted rock in an ore deposit that has to be separated during processing.
Why is the froth flotation method selected for the concentration of sulphide ores?
This method is based on the principle of the difference in the wetting properties of the ore and the gangue particles with the water and oil. This method is used for that metals whose ore gets preferably wetted by the oil and the gangue by the water. The sulphide ores preferably wetted by the oil and the gangue with the water. Hence this method is suitable for the concentration of the sulphide ore
What is the principle of magnetic separation?
Magnetic separation is technique used in metallurgyfor the concentration of ore particles. The principle of this method is that the magnetic ore particles can be separated from non magnetic impurities (gangue) or viceversa.
How did iron extract from the ground?
Smelting: Mined out of the ground, raw ore is a mixture of materials called ore proper and loose earth called gangue (waste). The ore proper is separated by crushing the raw ore are simply washing away the lighter soil. Breaking down the ore from its impurities is more difficult.
What two problems can result from removing waste material from ores?
It can be expensive and harmful to the environment.yes it can be harmful yet it can cause dormant toxins in the ore to become active.Not to mention that the more you mine the ore the actual gangue becomes higher than the actual value of the ore itself, therefore ridding it of the classification "ore"(gangue: the commercially valueless material in which ore is found.)(bold = edited by Ethan Urban)
What are the steps of concentration of ore?
The steps of concentration of ore include crushing and grinding the ore to reduce its size, separating the desired mineral from the gangue using physical or chemical methods (such as gravity separation or froth flotation), and further refining the concentrate to remove impurities. The final step involves smelting or refining the concentrated ore to extract the desired metal.
What are impurities of an ore called?
Gangue-In mining, gangue(pronounced "gang") is the commercially worthless material that surrounds, or is closely mixed with, a wanted mineral in an ore deposit. It 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.
