        <p>Растущая потребность в продукции черной металлургии обуславливает необходимость внедрения технологий, повышающих эффективность обогатительного передела железосодержащего сырья. Перспективным направлением в этой области является внедрение решений, основанных на возможности селективной дезинтеграции руд. Целью данной работы являлось установление закономерностей селективного разрушения железистых кварцитов на основании результатов исследования минералого-технологических свойств сырья. Представлены данные по изучению минералого-технологических особенностей железистых кварцитов Михайловского месторождения методами рентгено-флуоресцентного анализа и автоматизированного минералогического анализа. На основании исследований характера вкрапленности и размеров зерен породных и рудных минералов сформулированы задачи рудоподготовительного передела. В результате изучения измельчения руды установлены параметры распределения железа и оксида кремния по классам крупности в продуктах измельчения. На основании эмпирических зависимостей спрогнозирована крупность измельчения, при которой должно достигаться максимально эффективное раскрытие сростков рудных минералов и их минимальный переход в класс крупности –44 мкм.</p>

        <p>The growing demand for ferrous metallurgy products necessitates the introduction of technologies that increase the efficiency of the processing of iron-bearing raw materials. A promising trend in this area is the implementation of solutions based on the possibility of selective disintegration of ores. The purpose of this work was to establish the laws of selective disintegration of ferruginous quartzites based on the results of the study of mineralogical and technological properties of raw materials. We present data on the study of mineralogical and technological features of ferruginous quartzites of the Mikhailovskoye deposit. The data were obtained using X-ray fluorescence analysis and automated mineralogical analysis. Based on studies of the nature of dissemination and the size of grains of rock-forming and ore minerals, the tasks of ore preparation are formulated. The parameters for the iron and silicon oxide distribution by grain-size classes in the grinding products were established during the study. Based on empirical dependences, the grain size of grinding was predicted, at which the most effective release of intergrowths of ore minerals and their minimum transition to the size class of –44 µm should be achieved.</p>
