The aim of the invention is to increase the through recovery of cobalt. For this purpose, when converting matte, a crrc together with blast-furnace slag is used as a flux, maintaining the CaO / SIO ratio in the slag within 0.2-1.0, and at the depletion stage the ratio is reduced to 0.1 05 2 table.

Изобретение относитс к цветной металлургии , в частности к технологии переработки штейнов шахтной плавки окисленных никелевых руд.The invention relates to non-ferrous metallurgy, in particular, to the technology of processing of mine smelting of oxidized nickel ores.
Цель изобретени - повышение сквозного извлечени кобальта.The purpose of the invention is to increase the through extraction of cobalt.
Способ осуществл ют следующим образом .The method is carried out as follows.
На расплав штейна, содержащего, %: NI 15; S 20; Со 0,7 и Fe 60, загружали смесь доменного шлака (SI02 36,6; СаО 37,4; FeO 1.4, 10,6 и МдО 8,5) и кварцевого флюса (SI02 86%), массу продувают воздухом (температура 1250-1300° С) до получени жидкого шлака. Содержание никел в сульфидной массе после продувки 40-47%, кобальта 0.3-0,4%. Составы полученных шлаков (табл.1) свидетельствуют, что в пределах изменени CaO/Sl02 от 0,2 до 1,0 вThe melt of matte containing,%: NI 15; S 20; With 0.7 and Fe 60, a mixture of blast-furnace slag (SI02 36.6; CaO 37.4; FeO 1.4, 10.6 and MDO 8.5) and quartz flux (SI02 86%) was charged; air was blown through the mass (temperature 1250 -1300 ° C) to produce liquid slag. The nickel content in the sulfide mass after purging 40-47%, cobalt 0.3-0.4%. The compositions of the slags obtained (Table 1) indicate that within the range of CaO / Sl02 from 0.2 to 1.0 V
шлак переходит наибольшее количество ко бальта (в сравнении с известным и базовым объектом).slag goes over the greatest amount of cobalt (in comparison with the known and basic object).
Шлак, полученный после конвертировани подвергали обеднению, смесью пирита (86% FeS2) и коксовой мелочи (возможно использование шлака от производства фер- лосилици - ШФС).The slag obtained after the conversion was subjected to depletion, a mixture of pyrite (86% FeS2) and coke breeze (it is possible to use slag from the production of ferrosilicon — ShFS).
При этом достигаютс показатели г одставленные в табл 2When this is achieved, the indicators r set in table 2
Таким образом суммарное извлечение кобальта из штейна шахтных печей в кобальтовый штейн в предлагаемом способе составл ет51 55% против50% побазопому и 36% по известному.Thus, the total extraction of cobalt from the matte of the shaft furnaces to cobalt matte in the proposed method is 51 55% versus 50% for the bazopome and 36% for the known.
