Resumen

TAVERA, F. J.  y  ESCUDERO, R.. Effect of Solids on Gas Dispersion Characteristics: Addition of Hydrophobic and Hydrophilic Solids. J. Mex. Chem. Soc [online]. 2012, vol.56, n.2, pp.217-221. ISSN 1870-249X.

There is a controversy on the role of solids in flotation systems in terms of the characteristics of the solid-liquid-gas dispersions. The effect of slurries containing carbon or silica on the characteristics of gas-slurry dispersions generated in a flotation column was studied. Experimental results suggest that hydrophilic solids prevent bubbles coalescence, and produces large bubble surface areas, available to collide and collect particles during flotation. On the other hand slurries with hydrophobic particles produce larger bubbles, affecting both the performance and the hydrodynamics of the process.

Palabras clave : hydrophobic solids; hydrophilic solids; gas hold-up; superficial bubble surface flux; bubble coalescence.
