В лабораторных условиях для титаномагнетитовой руды выполнена оценка возможности увеличения выхода хвостов сухой магнитной сепарации (СМС) до 30 % при массовой доле железа в них не более 6 %. Приведены результаты испытаний СМС при крупности руды Р95 = 6, 10 и 30 мм и схем СМС с последовательным и параллельным обогащением крупных и мелких классов крупности. Дано теоретическое обоснование большей эффективности СМС при использовании двухбарабанного сепаратора по сравнению с однобарабанным. Рекомендована схема с СМС при крупности Р95 = 10 мм с применением данного сепаратора с различными индукциями магнитного поля для верхнего и нижнего барабана.
