Question

What is Gangue in chemistry?

Answer 1

Hint : We know that the Gangue is the unwanted material or the impurities present in the ore. It is commercially worthless. Gangue is the impurity that surrounds or is closely mixed with the ore deposit in which the minerals are present. Gangue is composed of waste rocks, stone and extra unwanted materials that are mixed up with the ore during its extraction.

Complete Step By Step Answer:
Gangue has no market value. It is waste rock or sand or soil. It is present along with minerals in the ore deposit from which the metal is to be extracted. Gangue is different from overburden and tailings. Overburden is the waste rock that is present above the ore deposit. Tailings are pieces of rocks from which valuable minerals are already stripped of by natural processes. Of the given options, select the options that are present in ore and are unwanted. Ore contains minerals with metals. Extraction of metal from ore by mining is economical. Metal ores include oxides, sulphide and silicates. Mineral is an inorganic solid substance that is naturally occurring and contains metals.
The extraction of metals from minerals is economically not feasible. The gangue in chemistry can be defined as an unwanted material or impurities in the form of sand, rock or any other material that surrounds the mineral in an ore deposit. This substance is common when it comes to the aspect of mining. Usually, gangue has to be separated from minerals and the process used is known as mineral dressing, mineral processing or ore dressing.

Note :
Remember that there are different methods of separation of the gangue from the ore depending upon the mineral ore and the type of gangue. The process of separation of minerals from the gangue is called mineral processing, mineral dressing, or ore dressing.
