Изобретение относитс к области переработки металлургических шлаков, в частности ванадийсодержащих.This invention relates to the processing of metallurgical slags, in particular vanadium-containing slags.
Известен способ переработки ванадийсодержащих шлаков, включающий операции измельчени и сухой магнитной сепарации .There is a known method for processing vanadium-containing slags, which includes grinding and dry magnetic separation operations.
Недостатком этого способа вл етс низка эффективность процесса извлечени ванади в силу неполного раскрыти полезного компонента.The disadvantage of this method is the low efficiency of the vanadium extraction process due to the incomplete disclosure of the useful component.
Целью изобретени вл етс повышение эффективности процесса извлечени ванади за счет изменени физико-механических свойств материала.The aim of the invention is to increase the efficiency of the vanadium extraction process by altering the physicomechanical properties of the material.
Это достигаетс тем, что металлизованный продукт подвергают охлаждению хладагентом до криогенного состо ни с последующим самоизмельчением объединенных металлизованного и немагнитного продуктов .This is achieved in that the metallized product is subjected to cooling with a refrigerant to a cryogenic state with subsequent self-grinding of the combined metallized and non-magnetic products.
Предлагаемый способ осуществл етс следующим образом.The proposed method is carried out as follows.
Шлак крупностью 300-О мм направл ют на сухую магнитную сепарацию. Выделенный металлизованный магнитный продукт охлаждают воздействием хладагента при температуре пор дка -180° С. Металлизованный продукт объедин ют с немагнитным продуктом и направл ют на самоизмельчение , после чего направл ют измельченный материал на магнитную сепарацию с предварительной классификацией, немагнитный продукт сепарации вл етс очищенным ванадийсодержащим шлаком.Slag size of 300-O mm is directed to dry magnetic separation. The recovered metallized magnetic product is cooled by exposure to a refrigerant at a temperature in the order of -180 ° C. The metallized product is combined with a non-magnetic product and sent to self-grinding, then the crushed material is directed to magnetic separation with preliminary classification, the non-magnetic separation product is purified vanadium-containing slag .
Глубокое и резкое охлаждение металлизованного магнитного продукта до температуры -180° С, т. е. до криогенного состо ни , измен ет его физико-механические свойства, делает продукт хрупким, легко поддающимс раскалыванию и измельчению . Объединение металлизованного магнитного продукта с немагнитным позвол ет добитьс при соударении т желого металлизованного и более легкого неметаллизованного продуктов максимального эффекта при измельчении.The deep and rapid cooling of the metallized magnetic product to a temperature of -180 ° C, i.e., to a cryogenic state, changes its physical and mechanical properties, makes the product brittle, easily cracking and crushing. Combining a metallized magnetic product with a nonmagnetic allows one to achieve the maximum effect during grinding when a heavy metallic and lighter nonmetallized product collides.
