Match the following:Column-I Column-II (A) Zone refining (P) pig iron (B) Electrolysis (Q) Al (C) Reverberatory furnace (R) Si (D) Blast furnace (S) Cu
| Column-I | Column-II |
| (A) Zone refining | (P) pig iron |
| (B) Electrolysis | (Q) Al |
| (C) Reverberatory furnace | (R) Si |
| (D) Blast furnace | (S) Cu |
A-R, B-Q, C-S, D-P
A-Q, B-P, C-S, D-R
A-P, B-S, C-Q, D-R
A-S, B-P, C-R, D-Q
The Correct Option is A
Solution and Explanation
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

Occurrence of metals
The existence of metals often plays an important role in our survival, even if we are unaware of them. Our reliance on metals has been strong since the old industrial era. From buildings to jewelry, we utilize them for everything. But where do we acquire these metals from and how are they made? Let's read the occurrence of metal in more detail.
Metals are found in the earth's crust, and it seems to be a good place to extract them through various processes such as metallurgy. The process of extracting metals from ores is called metallurgy. Mining is the most common method of extracting metals from the earth.
In nature, metals are mostly found in mixed conditions. However, they can also be found in a free state. In its natural state, a native metal is one that can be found in its pure form or as part of an alloy. Most metals are exposed to natural processes such as oxidation and corrosion. As a result, only non-reactive metals such as gold, silver, platinum, and others are discovered in their native or open-free condition. Most metals are obtained as compounds, which must be filtered to remove contaminants before being employed in numerous applications.
