Energy-driven phase changes of bauxites

Bauxites from the Vezhayu-Vorykvinskoe deposit (Middle Timan, Russia) are characterized by a considerable iron content, which negatively affect the ore proccesing. Using modern instrument base for mineralogical studies the author conducted test experiments proving the changes of phase composition and magnetic properties of bauxites after thermal and radiation-thermal processing. The results will allow reconsidering technologies of bauxite processing.
