Description
Примен емый в насто щее врем дл переработки окисленных никелькобальтовых руд кричный процесс обладает р дом недостатков, к которым могут быть отнесены низка производительность, большой износ футеровки, неустойчивость процесса и повышенна его чувствительность « изменению состава руд, неоднородность крицы и высока стоимость передела.The crying process currently used for the processing of oxidized nickel-cobalt ores has a number of drawbacks, which can include low productivity, high lining wear, process instability, and its increased sensitivity to changes in the composition of ores, heterogeneity of chips, and high conversion costs.
Новый полукричный способ переработки бедных железных и окисленных никелькобальтовых руд не имеет этих недостатков. Процесс проводитс при пониженных конечных температурах (1100-1200°), когда сопутствующа порода не переходит в расплавленное жидкое состо ние , а доводитс только до начала разм гчени . В результате такого процесса восстановленные металлы получаютс в виде порошка, образующего в основной своей массе с частью пустой породы рыхлые гранулы. Разделение порошка и пустой породы после соответствующего измельчени может быть произведено механическим обогащением, например мокрой, -магнитной сепарацией в магнитном поле напр женностью 1500-2000 эрстед.A new semi-crisis method of processing poor iron and oxidized nickel-cobalt ores does not have these disadvantages. The process is carried out at lower final temperatures (1100-1200 °), when the accompanying rock does not enter the molten liquid state, but is brought only to the beginning of softening. As a result of this process, the recovered metals are obtained in the form of a powder, forming mostly loose granules with a part of the waste rock. The separation of powder and waste rock after appropriate grinding can be carried out by mechanical enrichment, for example, wet, magnetic separation in a magnetic field with a strength of 1500-2000 oersted.
Проведенные на двухступенчатой трубчатой печи (диаметром 1 м и длиной И м) полупромышленные испытани процесса подтвердили возможность извлечени в концентрат из бедных руд 0,9% никел , 0,1% кобальта иоколо 30% железа. Никель и кобальт практически извлекаютс полностью, а железо до 75-80%. При этом производительность установки оказалась в 1,5 раза выше, чем при кричном процессе, а расход восстановител -на 25i°/o ниже.The semi-industrial process tests carried out on a two-stage tube furnace (1 m in diameter and I m in length) confirmed the possibility of extracting 0.9% nickel, 0.1% cobalt and about 30% iron into a concentrate from poor ores. Nickel and cobalt are practically completely removed, and iron up to 75-80%. At the same time, the plant capacity was 1.5 times higher than with the flash process, and the consumption of the reducing agent is 25i ° / o lower.
Предмет изобретени Subject invention
Полукричный способ переработки бедных железных и окисленных никелькобальтовых руд в трубчатых печах, отличающийс тем, что, с цедью,.получени восстановленных металлов и пустой породы в виде порошка, исходную руду подвергают нагреву до 1100-1200 а восстановленные таким путем металлы от пустой породы отдел ют известными способами, например магнитной сепарацией.A semi-critical method of processing poor iron and oxidized nickel-cobalt ores in tube furnaces, characterized in that, with the receipt of obtaining reduced metals and waste rock in powder form, the original ore is heated to 1100-1200 and the metals recovered in this way are separated from the waste rock by known methods, for example magnetic separation.
