Gangue minerals are the worthless material that surrounds, or is closely mixed with a wanted mineral.
- So when you extract Nickel from Nickel Ore you end up with the concentrated Nickel and also the gangue minerals which surrounded it.

What is flotation in separating mixture?
In chemistry, the flotation method is used to separate substances that repel water and substances that is attracted to water. It has a variety of applications and is often used to extract mineral ores from its surroundings.
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.
What is concentration of ores called?
Concentration of ore Unwanted rocks, sand and grit from the mineral ore are called gangue or matrix. These have to be removed so that the mineral ore is concentrated with higher percentage of metal. Ores are mined from deep within the earth's crust in the form of rocks. The minerals are embedded in these rocks. The rocks are first crushed into smaller pieces by crushers. Then they are ground to powder by ball mill and other processes so that powdered ore is obtained. Depending on the type of ore, hydraulic washing, froth floatation process, magnetic separation and chemical separation techniques are applied for concentrating an ore.
What is the difference between a metal a mineral and an ore?
Mineral,is a naturally occurring material in which metal or its compounds occur.An ore is that mineral in which metal is present in large quantity and from which the metal can be extracted in pure and high quality,economically.
Can diamonds float on water?
No, because they are too heavy. The only rock that will sometimes float on water is pumis. Although, you may coat small (roughly 1mm diameter) diamonds in pine oil and then they will float. They are presently using a process called froth flotation to remove diamonds from gangue minerals at a mine called EKATI in canada. Diamonds are naturally hydrophobic, you just need them to be small enough so that the force exerted by the surface tension outweighs the force applied by gravity.
What is the relationship between mineral ore and gangue?
Gangue is the undesired material of an ore.
Why is gangue sometimes reprocessed?
Gangue is sometimes reprocessed for the sake of obtaining extra minerals. This can be done with both the new and old methods in mining.
What is the waste material that must be separated from an ore?
gangue
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.
Why is gangue rock reprocessed?
because it can be used in industrial ways
What is flotate in?
Flotation is a process of separation of an useful mineral from gangue.
What waste rock can be removed before a mineral can be used?
Gangue
What is the name of a process by which low-grade ore is separated from gangue?
refining
What waste rock must be removed before a mineral can be used?
Gangue
Waste rock that must be removed before a mineral can be used?
Gangue
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 waste rock that must be removed before a mineral can be use?
In mining this is known as "gangue".
