Изменение фазового состава и физических свойств хромовых руд массива рай-из при окислительном обжиге

Abstract

Представлены результаты исследований кристаллохимических превращений и диффузионных процессов, протекающих в хромовых рудах в окислительных условиях изотермического обжига при 900, 1000 и 1100 °С. Установленные закономерности позволяют разработать способ обогащения руды с извлечением примесных полезных элементов и увеличить соотношение Cr/Fe в концентрате. The article represents the results of research of crystal-chemical transformations and diffusion processes occurring in chromic ores during the oxidizing conditions of the isothermal roasting at 900, 1000 and 1100 °C. The established patterns allow to develop the method of ore enrichment with extraction of useful impurity elements and to increase the ratio of Cr/Fe in a concentrate.
