Correlation of Adsorption of Surfactants with Fracture and Grinding of Quartz

  • Hassan El-Shall

Fracture of quartz by single impact as well as wet ball milling is studied in presence of different surfactants (dodecylammonium chloride), and inorganic electrolytes (A1Cl3, CaCI2 ). The data show an increase or decrease in fracture efficiency depending on parameters such as pH, type and concentration of added surfactant. Adsorption of these chemicals as indicated by their effect on surface properties such as zeta potential, and pulp characteristics including flocculation and fluidity, is correlated with the ionic species distribution, and fracture and grinding results. Such correlation shows, in general, that fracture efficiency is higher under pH conditions where surface active species are dominant.
