Abstract
1. Способ переработки окисленных никелевых руд, включающий расплавление, восстановление и сульфидирование шихты, состоящей из руды, сульфидизатора, топлива, восстановителя и флюсов, с подачей дутья и с получением штейна и шлака, отличающийся тем, что, с целью удешевления процесса, увеличения межремонтной кампании конвертеров за счет получения штейна с высоким содержанием серы и никеля, а шлака с низким содержанием никеля и кобальта, расплавление шихты, восстановление и сульфидирование расплава ведут в шлаке при 1250 - 1440C при подаче в него дутья и сульфидизатора и при противоточном движении штейна и шлака.2. Способ по п.1, отличающийся тем, что в качестве топливовосстановителя используют уголь.1. A method of processing oxidized nickel ores, including melting, reduction and sulphidation of a mixture consisting of ore, sulphidization, fuel, reducing agent and fluxes, with blowing and producing matte and slag, characterized in that, in order to reduce the cost, increase the overhaul campaigns of converters due to the production of matte with a high content of sulfur and nickel, and slag with a low content of nickel and cobalt, melting of the charge, reduction and sulfidation of the melt are carried out in the slag at 1250 - 1440C when fed into it rd and sulphidizer and countercurrent motion matte and shlaka.2. The method according to claim 1, characterized in that coal is used as a fuel replenisher.
