Magnetite ore quality depends on their form conditions. Information on the genesis of magnetite<br>deposits affords to find them more qualities. In this work samples of different types of magnetite ore<br>were investigated on their magnetic properties. During the remagnetting of magnetic minerals an high<br>frequency sound appears, it brings some information on sample’s magnetic structure. This objective<br>information affords to explore the physic-chemical processes, that were taken over with iron ore<br>samples. Acquired data allows to pick out different magnetite generations, and also brings some<br>information on anisotropy of sample’s physical properties.
