The study focuses on interaction between monomineral fractions of quartz and magnetite in aqueous environment. The interaction conditions and mechanism of the minerals in an alkaline water medium are found. In the course of wet grinding, submicron-size particles of quartz vigorously attach to the surface of basic ore mineral—magnetite, which reduces efficiency of mineral dissociation, levels difference in their surface properties and, as a consequence, degrades their disintegration in a real separation medium. Attraction, attachment and holding of submicron-size quartz particles is promoted by mechanical forces of grinding and by charges caused by natural piezoelectric effect on the surface of quartz. The optimal adhesion activities of submicron-size particles of ferruginous quartz and magnetite lie in the same interval of pH = 7.5–9.5 and are characterized with the same wettability. The minimum force of adhesion interaction in the liquid medium of separation for the contacting submicron-size particles is 6.7 · 10–7 dyne for quartz and 20.6 · 10–7 dyne for magnetite. It is shown that attraction, strong attachment and holding of submicron-size quarts particles on the surface of magnetite during their joint wet grinding is facilitated by the condition and medium of disintegration.
