The ore particles of D ave = 23.6 mm were used to investigate the effect of air velocity u 0 /u mf on the float-sink at t f − s = 5 min. Fig. 2 shows x f − s as a function of ρ for each u 0 /u mf.The x f − s for the low density ore particles is 1 and that for the large density ones is 0, indicating that the former particles float and the latter particles sink.

Hydraulic washing is the process based on the difference in densities of ore and gangue particles. Froth floatation method is used for ores with different wetting properties of ore and gangue particles. On adding sulphide ore in a mixture of oil and water, the sulphide particles are wetted by oil and gangue particles are wetted by water.
