Features of mineral composition of garnet-bearing shales of the Kryvyi Rih basin and recommendations for further processing

In addition to iron ore, the deposits of the Kryvyi Rih basin contain about 50 types of metallic and non-metallic minerals, which are simultaneously extracted from the subsoil during the exploitation of the deposits and can be used in the national economy of Ukraine. An important place among them is occupied by garnets, which are rock-forming minerals of some types of granitoids, gneisses and crystalline shales. Garnet-bearing shales are widely distributed within the Kryvyi Rih basin. In this paper, we investigated garnet-bearing shales of the Hannivske field from the Northern region of the Kryvyi Rih basin. Based on the results of detailed studies, the mineral composition was established, their varieties were identified, and mineralogical recommendations for further processing technology were given.
