The authors describe the research findings on the physicochemical properties of old ferruginous quartzite tailings of the Kursk Magnetic Anomaly using the methods of the laser diffraction, spectrophotometry for tracing distribution of adsorption centers and the scanning electron microscopy. It has been found that the surface of old tailings features higher total content of active centers that influence strength, density and hydration capacity of cement as against natural quartz sand, conventionally included in backfilling composites, and the current ferruginous quartzite tailings. The chemical mapping has proved that additional milling is required to improve uniformity and homogeneity of distribution of elements on the surface of tailings as well to intensify their activity as a component of a composite binder. The article offers compositions of cement-free and low-cement backfill composites with the ultimate compression strength of 5.5–7 MPa. The conditions and parameters of the procedure for preparation of old tailings and other kind mineral waste for introduction to the cement-free backfilling composite mixture are described.
The research has been implemented using equipment of the Shared Use Center for Diagnostics of Structure and Properties of Nanomaterials at the Belgorod National Research University.
