The paper presents the results of gravity separation of different types (Karelian-Kola region) of fine-sized mica ores. According to the technique, specific-sized concentrates are separated by both slot and hydraulic separators, and by other gravity separation equipment. The technique provides processing of non-economic muscovite ores and their dumps, of industrial types of vermiculite ores, as well as of phlogopite raw materials from the Kovdor deposit, mica recovery amounting to 60–70%.
Ключевые слова Fine-sized mica, muscovite, phlogopite, vermiculite, sphericity coefficient, free settling rate, slot separator, hydraulic separator.
