Among the following separation processes, concentration technique is used in the-----
Correct answer: D. Both (b) and (c)
- A. Calcination
- B. Froth floatation
- C. Leaching
- D. Both (b) and (c)
Explanation
Option D is correct. Froth floatation and Leaching are both concentration techniques used in the separation of metals. Froth floatation concentrates minerals based on their wettability, while leaching dissolves the desired metal from an ore. Calcination, on the other hand, is a process used to remove impurities through high-temperature heating, but it is not a concentration technique in metal separation.

About s-Block and p-Block Elements
The s and p blocks are studied through their valence-shell configurations, periodic trends and characteristic chemical properties. Work covers the reactions of Group I and Group II elements, the behaviour of Group IV elements, and how atomic size, ionization energy, electronegativity and metallic character change across periods and down groups.
