Question
Ores of some important metals are provided in column-I with that metal in column-II respectively.Column-IOreColumn-IIMetal(a)Siderite(p)Zinc(b)Malachite(q)Iron(c)Sphalerite(r)Aluminium(d)Kaolinite(s)Copper
Solution
The correct matching between the ores and their respective metals is as follows:
(a) Siderite - (q) Iron Siderite is an iron carbonate with a chemical formula of FeCO3. It is a valuable iron mineral, since it is 48% iron and contains no sulfur or phosphorus.
(b) Malachite - (s) Copper Malachite is a copper carbonate hydroxide mineral, with the formula Cu2CO3(OH)2. It is a rich source of copper.
(c) Sphalerite - (p) Zinc Sphalerite is a zinc sulfide mineral, the most common zinc ore. It has a chemical formula of (Zn, Fe)S.
(d) Kaolinite - (r) Aluminium Kaolinite is a clay mineral, part of the group of industrial minerals with the chemical composition Al2Si2O5(OH)4. It is a layered silicate mineral and the main component of kaolin, which is used in the production of ceramics and as a filler in paper manufacture. It is a source of aluminium.
