Define the terms: (a) Mineral (b) Ore (c ) gangue |
|
Answer» Solution :The inorganic or compound, which occurs naturally in the earth.s crust is called mineral. For example, COPPER pyrites `(CuFeS_2)` cuprite `(Cu_2O)` etc are the minerals of copper. (b) The mineral from which a metal can be exerted profitably and conveniently is called an Ore. For example,bauxite `(Al_2O_3,2H_2O) ` and clay `(Al_2O_3.2SiO_2.2H_2O)` ar the minerals of aluminium. But EXTRACTION, of aluminium is cheaper and easier from bauxite.Hence bauxite is the ore of aluminium. Thus every ore is a mineral but every mineral is not an ore. (C ) The unwanted impurities of sand and rocky materials present in the ore are known as GANGUE or matrix. We get a CONCENTRATED ore by removing the gangue present it it. |
