        <p>Комплексные магнетитовые руды типичны для контактово-метасоматических железорудных месторождений. Кроме железа они содержат серу, кобальт, медь, свинец, ванадий, фосфор и другие ценные ком­поненты. В настоящее время из магнетитовых руд извлекают сульфидные концентраты: кобальт-пиритный, медный, свинцовый и цинковый, в бу­дущем возможно извлечение апатита, кальцита, а иногда и датолита. ...</p>

        <p>Complex magnetite ores are typical for contact-metasomatic iron ore deposits. In addition to iron, they contain sulfur, cobalt, copper, lead, vanadium, phosphorus and other valuable components. At present, sulfide concentrates are extracted from magnetite ores: cobalt-pyrite, copper, lead and zinc, in the future it is possible to extract apatite, calcite, and sometimes datolite. ...</p>
