Question

Define froth floatation.

Answer 1

• Froth flotation is a highly versatile method used for selectively separating hydrophobic particles, i.e water repellent from hydrophilic particles, i.e. having an affinity for water on differences in the ability of air bubbles.
• It is used to raise the low mineral concentrations in ores to concentrations that can be more economically processed.
• It is mainly used for the concentration of sulfide ores.
