The article deals with the study of geotechnical conditions in Kryvbas. The major factors of technogenic changes in an ecological state of the geological environment during development of ferruginous quartzite deposits have been determined. The big mining complex in Kryvbas is a complex natural-technogenic geosystem with the mainly irreversible use of raw material resources the renewable ability of which is quite low. One of the main factors of the environmental impact of PGTS Kryvbas is the formation of signi

Iron Ore Deposits

Specific characteristics of iron ore deposits in Ljubija ore region are given by pelitoid iron ores (,,brand“) which occupy a substantial part of iron mineral resources, on which industrial production of natural iron oxide – pigments depends. This particular technology type of iron ore deposits, until recently was waste from mining production, and now when it is possible to implement new technological processes, that waste became an important commercial product. This paper presents the results of detailed geological research which lasted for a few years, as well as laboratory and tehnological tests. It presents the new data on the metallogenetic characteristics of the environment where iron oxides originate as a raw material for mineral pigments. In this paper, we answered and resolved dilemma about brand identity in adequate genetic iron types in Ljubija mining regions, about their specificity as well as the ore formations and geohistorical development. Through the technological characterization of the ore and its domain of application, we provide the basis for economic evaluation of the deposits of this very important mineral resource.
