Принципиально вихретоковую сепарацию можно использовать при обогащении рудных немагнитных минералов. Для расчета силы Ампера, действующей на частицы в барабанном вихретоковом сепараторе, выведена формула с использованием законов электродинамики. Выполнено математическое моделирование с оценкой величины силы Ампера, действующей на металлические частицы Au, Al, Cu, Pb и на халькопирит, пирит и самородное золото. Рассмотрены основные параметры и режимы барабанного вихретокового сепаратора, влияющие на эффективность обогащения. Приведены результаты опытов по разделению металлических частиц Al, Cu и Pb и выделению частиц пирита в проводниковую фракцию в барабанном вихретоковом сепараторе. Эксперименты подтвердили выводы, сделанные при математическом моделировании. Применение вихретоковой сепарации для сухого обогащения частиц рудных немагнитных минералов при современном уровне развития техники малоперспективно.
