1.	Write the physical methods used for the concentration of the ore. Explain the method used for concentration of the sulphide ore.
Answer» Physical methods used for the concentration of the ore is, i) Hand Picking ii) Washing iii) Froth floatation iv) Magnetic Separation. Concentration of sulphide ore : 1. Sulphide ore is concentrated by using froth floatation Method. 2. The ore with impurities is timely powdered and kept in water taken in a flotation cell. 3. Air under pressure is blown to produce froth in water. 4. Froth so produced, taken the ore particles to the surface whereas impurities settle at the bottom. 5. Froth is separated and washed to get ore particles.

1. Sulphide ore is concentrated by using froth floatation Method.

2. The ore with impurities is timely powdered and kept in water taken in a flotation cell.

3. Air under pressure is blown to produce froth in water.

4. Froth so produced, taken the ore particles to the surface whereas impurities settle at the bottom.

5. Froth is separated and washed to get ore particles.
