Belitska M. Lithology and technological properties of the bottom sediments of rivers of Dnieper-Bug estuary

Lithology of different genetic types of modern sediments researched, built lithological column and cuts of individual sections of the Dnieper, Ingulets, South-ern Bug. Characterized by the role of man-made and natural factors in the for-mation of modern alluvium. The study of the lithological-technological features of bottom sediments allowed characterize by processes of sedimentation and the for-mation of "man-made deposits" in the rivers of the Dnieper-Bug estuary. Defined the technological properties of bottom sediments of rivers Dnieper-Bug estuary and offered a general scheme of complex processing of modern alluvium. Lithological cuts of the upper layer of bottom sediment in profiles of the most representative sites of the river Ingulets reflect the impact of technogenetic factors, designated as mixing layers of sediment and accumulation of crushing products and beneficiation of ferruginous quartzite. These areas are promising to processimg of sediments and getting of iron ore concentrate with mass content of iron 65,4%. Modern riverbed and floodplain deposits of the Dnieper, Southern Bug, In-gul, Ingulets and its tributaries contain elevated concentrations of heavy minerals: almandine, ilmenite, zircon, monazite and a range of man-made components: grains smelting iron, copper, bronze and other alloys. For complex processing of sediments polymineral proposed multistage separation with sequential release of several monomineral concentrates. In addition to economic benefits, it has also ecological value, because it provides a cleaning of river, network from industrial pollution.
