Question

Cryolite is the chief ore of?

Answer 1

Hint : We need several raw materials for the construction of the various goods like for construction of roads we need coal tar etc. Similarly these raw materials are not like this in nature. The raw goods are impure or highly pure which either are not of use or are very unstable at ordinary conditions. For example, pure gold is liquid and cannot be used like an ornament but with the addition of some impurity the gold gets stability and the stable ornament gold is prepared.

Complete Step By Step Answer:
The natural form of an element in the form of a metal or a non metal along with impurities occurring in the earth crust is called a mineral. And when, a metal of requirement is extracted from the mineral given that it does not affect the environment badly and does not require high investment is termed as an ore. And the phenomena via which a desired metal is extracted from the ore is called metallurgy.
Some important metallurgical processes are (i) crushing, (ii) grinding, (iii) benefaction, (iv) extraction, (v) refining.
Some metals and their minerals are: - (i) Aluminium has bauxite, kaolinite, (ii) Iron has haematite, magnetite, siderite, iron pyrites, (iii) Copper has copper pyrites, malachite, cuprite, chalcocite, (iv) Zinc has sphalerite, calamine, zincite.
Cryolite is the chief ore of aluminium.

Note :
The extraction of the metal in the safest manner that it does not affect ecology and not the pocket of an individual is called ore and the phenomena is metallurgy. Aluminium is used as silver foil to wrap the food, making paints, bulbs, powder, is a good conductor thus highly required by the automobile industry.
