Objects of research - the collection of samples of goetite and hematite ores from deposits of Krivoy Rog and Kerch regions. Research methods and apparatus: magnetometry method (magnetometer with Hall sensor), magnetic resonance method (EPR spectrometer RE- 1306 (Russia ), PS100X (Belarus)) , X-ray diffraction (DRON -4M), NGR spectroscopy , X-ray fluorescence analysis. Collections of goetite and hematite ores from deposits of Krivoy Rog and Kerch regions were created.

Collection of samples of iron oxides and hydroxides from iron ore deposits of the Krivoy Rog area, Kerch region and the Ural region are created. The phase composition, magnetic properties, chemical composition of the samples from created collections were determined.
