New Forms of Platinum Group Minerals in Ferruginous Quartzites of the Lebedyan Deposit, Kursk Magnetic Anomaly (Central Russia)

摘要

Two-thirds of the identified reserves and predicted resources of iron ores of Russia are concentrated in five (Mikhailovka, Lebedyan, Stoilo, Stoilo-Lebedyan, and Korobki) deposits of the Kursk Magnetic Anomaly (KMA). These deposits are developed by three (Mikhailovka, Lebedyan, and Stoilo) ore dressing plants that provide approximately 53% of raw iron ores mined in Russia. Noble metals are among the most essential and voluminous components extracted from ferruginous quartzites and tailings of ore dressing plants. The noble metals are essential unconventional byproducts of gold-platinum ores in the 21st century. Elucidation of the mode of occurrence of Au and platinum group elements (PGE) plays a crucial role in the choice and development of resource-saving high-tech methods for the comprehensive reworking of strategic metals.
