    Dec 31, 2021 Froth flotation is a physico-chemical process whereby mineral particles are separated based on their affinity for an air environment. Particles with a high affinity for an air environment (hydrophobic) will attach to rising bubbles and float to the froth phase, thus being separated from the particles that have an affinity for water molecules

This is permissible because jigging could also be viewed as a repetitive process of fluidization and defluidization which takes place under rapid rate of change of water velocity [9-10].
