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 the relationship between mineral ore and gangue?
Gangue is the undesired material of an ore.
What is difference between slag and matte?
slag is iron silicate (FeSiO3) while Matte is a crude mixture of molten sulphides.
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 distance between Cardiff and Paignton?
a slag
What is the difference between dross and slag?
Dross is the waste or impurities that float to the surface of molten metal, while slag is the byproduct of processing metal ores. Both dross and slag are forms of waste material produced during metal production processes.
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.
Why is the froth flotation method selected for the concentration of sulphide ores?
Froth flotation is commonly used for the concentration of sulphide ores because it exploits the differences in surface properties of sulfide minerals and gangue minerals. The process involves adding special reagents that selectively bind to the sulfide minerals, allowing them to attach to air bubbles in a froth and be separated from the gangue material. This method is effective for separating valuable sulfide ores from unwanted gangue minerals.
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.
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 homophone of gang?
The homophone of "gang" is "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.
Is coke used to oxidise slag?
Coke is not used to oxidize the slag . It is carbon that is used to oxidize slag.
