Gangue is the waste rock or materials overlying an ore or mineral body that are displaced during mining without being processed or simply rocky impurities.
While slag is usually a mixture of metal oxides and silicon dioxide. However, slags can contain metal sulfides and elemental metals. While slags are generally used to remove waste in metal smelting, they can also serve other purposes, such as assisting in the temperature control of the smelting, and minimizing any re-oxidation of the final liquid metal product before the molten metal is removed from the furnace and used to make solid metal.

What is a gangue?
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 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.

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
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 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
