Magnetic separation is used for increasing concentration of the following:
Correct answer: C. Hamatite
- A. Horn silver
- B. Calcite
- C. Hamatite
- D. Magnesite
Explanation
Haematite is the correct answer because it has magnetic properties, making it suitable for separation using magnetic separation techniques. The other options, such as Horn silver, Calcite, and Magnesite, do not possess magnetic properties and therefore cannot be separated using magnetic 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.
