Abstract

Ferromagnetic phases of magnetite quartzites and changes in the magnetic structure of magnetites of the Kremenchug iron ore district were studied. In addition to magnetites with impurities, at least 4 types of cation-deficient magnetites with Curie points near 300, 350, 400, and 500 °C and inversion temperatures above 700 °C were found in the ores.

In magnetite in association with cumingtonite on DTMA, splitting of the peak of magnetite with T_C = 546 into peaks with T_C= 517 and 570 ^oС of approximately the same intensity was detected. It is shown that this phenomenon indicates the presence in the ore of two types of magnetite with T_C =502 and 539 ^oС with greater and lesser coercive force, respectively.
