A process used for the Concentration of Ore is________?
Correct answer: B. Forth flotation
- A. Roasting
- B. Forth flotation
- C. Electrolysis
- D. Distillation
Explanation
Froth flotation concentrates sulphide ores by making the ore particles attach to bubbles and rise as froth, leaving much of the gangue behind. Roasting is a chemical conversion step after concentration, while electrolysis and distillation are not the usual concentration method for solid ores.

About Crystalline Solids
Crystalline solids contain particles arranged in a regular repeating lattice described by a unit cell. Their study includes coordination number, packing efficiency, density, anisotropy, cleavage, polymorphism and common crystal systems, along with ionic, molecular, covalent network and metallic crystals. Crystalline order differs from the random arrangement of amorphous solids.
