Abstract

Изобретение относится к области цветной металлургии, в частности к способу переработки латеритных (окисленных никелевых) руд с прямым получением ферроникеля в виде металлических гранул. Способ включает смешивание руды с твердым восстановителем и флюсующими добавками, брикетирование полученной смеси, восстановительный обжиг брикетированной шихты в трубчатых вращающихся печах с формированием крицы ферроникеля и выделение ферроникеля из измельченного клинкера. Флюсующие добавки вводят в смесь в количестве 6-12% CaCO, 6-12% AlO, 0-10% SiOот массы руды, максимальную температуру в зоне крицеобразования поддерживают в пределах 1300-1350°C и содержание остаточного углерода в клинкерном шлаке поддерживают в пределах 0,05-0,55%, предпочтительно в пределах 0,1-0,4%. В качестве твердого восстановителя используют смесь битуминозного угля и антрацита или кокса. Способ позволяет достигать высоких показателей при обжиге для повышения эффективности прямого получения ферроникеля из высокомагнезиальных силикатных никелевых руд.The invention relates to the field of nonferrous metallurgy, in particular to a method for processing lateritic (oxidized nickel) ores with direct production of ferronickel in the form of metal granules. The method includes mixing the ore with a solid reducing agent and fluxing additives, briquetting the resulting mixture, reducing the roasting of the briquetted charge in rotary tubular kilns with the formation of a ferronickel crumb and separating ferronickel from the crushed clinker. Fluxing additives are introduced into the mixture in an amount of 6-12% CaCO, 6-12% AlO, 0-10% SiO by weight of the ore, the maximum temperature in the zone of crone formation is maintained within 1300-1350 ° C and the content of residual carbon in the clinker slag is maintained within 0.05-0.55%, preferably in the range 0.1-0.4%. A mixture of bituminous coal and anthracite or coke is used as a solid reducing agent. The method allows to achieve high performance during roasting to increase the efficiency of direct production of ferronickel from high-magnesian silicate nickel ores.
