Приведены результаты исследования процесса формирования металлургических окатышей с 50-процентным содержанием вовлеченного красного шлама. Произведен подбор состава топливно-плавильной композиции, обеспечивающего ее формообразование и восстановительную способность. В качестве связующего материала и одновременно восстановителя Fe₂O₃ использовался верховой торф. В результате термообработки образуются магнитные фазы магнетита и маггемита, наличие которых позволяет применить магнитную сепарацию с получением железосодержащего продукта, пригодного для использования в качестве добавки к традиционной металлургической шихте.

Работа проведена при поддержке Международного центра компетенций в горнотехническом образовании под эгидой ЮНЕСКО по проекту «Наука» (г. Санкт-Петербург, РФ).
