On the basis of nonequilibrium electrophoretic mobility measurements b
y laser-Doppler electro-phoresis, the sign of the surface charge of al
kali halides in their saturated brines has been established. The resul
ts are generally as expected from simplified lattice ion hydration the
ory. This recent electro-kinetic information coupled with the stabilit
y and prevalence of collector colloids in such soluble-salt flotation
systems suggests that the selective flotation of alkali halides is due
to the adsorption of oppositely charged collector colloids by heteroc
oagulation. Experimental flotation results confirm this surface charge
/collector colloid adsorption model and are presented herein.
