Description

Примен емые способы извлечени  ванади  нз железо-ванадиевых концетратов, содержащих титан, не обеснечивают достаточно высокого извлечени  ванади .The used methods for vanadium extraction of titanium-containing iron-vanadium concentrates do not provide for a sufficiently high vanadium recovery.

ОпИсываемый снособ извлечени  ванади  из выеокот танистых железо-ванадиевых мелкозернистых концентратов выщелачиванием их водой значительно увеличивает извлечеНИе ванади  и обеспечивает достаточно нолное отделение его от железа и титана, а также сокращает продолжительность обжига.Desaned extraction method of vanadium extraction from tannite iron-vanadium fine-grained concentrates by leaching them with water significantly increases the extraction of vanadium and provides a sufficiently complete separation from iron and titanium, and also reduces the duration of calcination.

Достигаетс  это предварительным окислительиым обжигом концентратов , обеспечивающим переход магнетита в гематит и разрунление ванадийсодержащих мннера .IOB, что при последующем обжиге в присутствии сульфата натри  но обычной технологии нр иводит к переводу большей части ванади  в воднорастворимыо соединени .This is achieved by preliminary oxidizing roasting of concentrates, which ensure the transition of magnetite to hematite and the destruction of vanadium-containing miners.

Предварительный . обжиг осуществл ют в окислительной атмосфере в течение 2-3 час. пр,к 800- 950°. После этого огарок охлаждают , доизмельчают и обрабатывают в чашевом или барабанном гранул торе в присутствии насыщенного раствора сульфата натри  .Preview roasting is carried out in an oxidizing atmosphere for 2-3 hours. pr, to 800-950 °. After this, the calcine is cooled, crushed and processed in a pan or drum granulator in the presence of a saturated solution of sodium sulfate.

В раствор нереходит более 80% ванади , который затем осаждают обычным способом.More than 80% of vanadium does not form into the solution, which is then precipitated in the usual way.

Вьпцелаченный материал нодсушивамт и перерабатывают на чугун и высокотитанистые щлаки.The material bent is nodsivivamt and is processed into cast iron and high titanium slag.
