Solution
Zone refining is a very useful method to extract metals with high purity such as Silicon (Si) and Germanium (Ge).
Electrolytic method of Electrolysis: Aluminium (Al) ore is extracted by the process of electrolysis. Aluminium (Al) ore is called bauxite. and it is purified to produce aluminium oxide, a white powder from which aluminium can be extracted.
A reverberatory furnace is a furnace that is mainly used for the extraction of Tin, Copper, Aluminium and Nickel metals as well as in the production of certain concrete and cement. The furnace is mostly used for smelting and refining these materials.
Blast furnaces are used to extract pig iron from iron ore for subsequent processing into steel, and they are also used in processing lead, copper, and other metals.
Hence, correct match is-
(A) Zone refining - Silicon
(B) Electrolysis - Aluminium
(C) Reverberatory Furnace - Copper
(D) Blast Furnace - Pig Iron
The Correct Option is option A): A-R, B-Q, C-S, D-P
