Annotation:  The paper discusses the question of interaction of natural monomineral fractions of ore minerals (oxides of iron) of jaspilite KMA and sub-micron particle of quartz in their joint dry and wet grinding. The mechanism of their interaction with the joint grinding. The strength of the fastening and retaining of submicron particles of quartz on the surface of ore minerals was estimated mechanical otterrai, ultrasonic treatment and centrifugation. It is shown that the fastening and retaining of submicron particles of quartz on the surface of the ore minerals due to intermolecular interaction forces (van der Waals) that are listed in contact the crystal lattices of minerals. The magnitude of these forces depends on the structural-geometrical conformity of the contacting minerals. Established strong securing and retaining on the surface of the particles of ore minerals of submicron particles of quartz with a maximum size less than 0.8 microns, i.e., the formation of "industrial clusters". This reduces the effectiveness of the disclosure minerals, eliminates the difference in surface properties of the partial minerals.
