Исследована перспективность использования сухого магнитного обогащения в сепараторах различных конструкций для повышения качества ильменитового концентрата электрической сепарации. Осуществлена оценка применения сухой магнитной сепарации для извлечения ильменита из хвостов электросепарации. Теоретические расчеты показали, что разделение ильменита и породных слабомагнитных минералов в барабанном сепараторе с верхней подачей материала лучше проводить при индукции магнитного поля 0,45 Тл, в роликовом сепараторе с нижней подачей материала — при индукции 0,8 Тл. Сухую магнитную сепарацию можно применять для повышения качества ильменитовых концентратов с массовой долей диоксида титана менее 48 %. Сухое магнитное обогащение хвостов электрической сепарации позволяет получить продукт, аналогичный исходной руде по массовой доле диоксида титана. Такое обогащение продуктов электросепарации с технико-технологической и экономической точек зрения лучше проводить в сепараторах с верхней подачей материала.
