The critical contact angle was lowest for the particle size ranges that have relatively high flotation recovery, approximately 45176; for 2075 m particles, and it increases significantly outside this size range. Particle size also has been reported to have an effect on froth phase behaviour.
Contact UsFroth flotation is a physico chemical separation process. Separation is principally based on differences in surface hydrophobicity. However, particle size and density have a significant impact.
Contact UsIn froth flotation, adsorption is a strong consequence of surface energy, since the small particles have a high surface area to size ratio, resulting in higher energy surfaces to form attractions with adsorbates.
