Extracted in a solution of potassium chloride and determined by titration with NaOH. 5g of mica (particle size –150 +105mm) and 30ml of distilled water, at pH 10. The suspensions were agitated for 20 minutes and then let settle for 10 minutes. The supernatants were sampled, filtered and sent to chemical analysis of Al3+, total Fe, Mg2+, Ca2+ (by atomic absorption spectrometry) and K+ (by flame photometry). Oxidation-reduction potentials (ORP) of supernatants were measured at 22–23°C by ORP-meter Horiba D-24E, using Ag/AgCl as the reference electrode.

Since the value of contact angle (q) of a solid depends greatly on the magnitude of the surface tension of the solution (gLV) in which the solid is immersed, the lower is the magnitude of gLV, the lower is contact angle of mineral particles (Zizman 1964). Particles of Ca-bearing gangue minerals, such as dolomite and calcite, interact strongly with long chain collectors used in Brazilian phosphate plants, such as alkyl sarcosinate (Schroder 1986, Buttner 1987) and fatty acid soaps (Finkelstein 1989).

This finding indicates that an increase in surface tension of flotation solution at industrial circuit from 36–40mN/m to 53mN/m would increase the efficiency of the separation process. Since measurements of gLV for solutions taken from industrial circuit (rougher and cleaner) were carried out by the Du Nouy Method and gLV of methanol/water solutions was conducted by the Wilhelmy Plate Method, further work is required to confirm this trend.
