Copper pyrite ore is concentrated by:
Correct answer: C. Froth floatation process
- A. Electromagnetic method
- B. Leaching with NaCN method
- C. Froth floatation process
- D. Both A and C
Explanation
Option C is correct. Copper pyrite ore is concentrated by the froth flotation process. This process separates hydrophobic copper pyrite from hydrophilic minerals in the ore. The ore is added to a flotation cell where a frothing agent helps create bubbles that carry the hydrophobic material to the surface. This froth is then collected and processed to extract copper. The other options are incorrect because they do not effectively concentrate copper pyrite ore.

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.
