alleryThe froth floatation method of concentration is most suitable for which type of ore?
ACarbonate ores
BSulphide ores
COxide ores
DNitrate ores
Answer & Solution
Correct answer: B. Sulphide ores
1. Froth floatation uses hydrophobic and hydrophilic properties of particles.
2. Metal sulphide particles are hydrophobic and get wetted by oil, floating with the froth.
3. So this method concentrates sulphide ores such as zinc blende and copper pyrite.
4. Carbonate and oxide ores are not concentrated this way, so they are wrong choices.
