Description
Предлагаемый способ двухступенчатого отделени кобалг та от никел заключаетс в следующем. Первоначально из растворов кобальта, содер;ка;дих сравнительно большое KOVTHMCCTBG , выдел етс загр зне- ны11 кобальт при погиощи электролиза с нерастворимыми анодами, ириготозлениыми из кобальтокрелгниевого сплава. При электролизе раствороз , содержа:цих кобальт и никель в 4:1, получаетс .катодный осадок, в котором отношеи е кобальта к и 1кел;о равно 30:1. Электролиз ведетс при температуре 50 - 60, при плоткюсти тока на катоде 4-8 au/rf/j- при рН раствора 1,5-2 и iij}ii суммарном содержанш коба;1ьта и никел 30-70 г/.-.The proposed method for the two-stage separation of cobalt from nickel is as follows. Initially, a relatively large KOVTHMCCTBG is released from cobalt solutions, cobalt is contaminated, and electrolyzed with insoluble anodes, irigotozlenymi from cobalt-ramnium alloy. In electrolysis, dissolving, containing: cich cobalt and nickel in 4: 1, a cathode precipitate is obtained, in which the ratio of cobalt to and 1 kel is about 30: 1. Electrolysis is conducted at a temperature of 50–60, with a current density of 4–8 au / rf / j– on the cathode, with a pH of 1.5–2 and iij} ii the total content of coba, 1g and nickel 30–70 g /.-.
О5разую:ца с ири этом свободиа i-inc.iOTa нейтрализуетс jeлo.Oruha: iri inca ii ia inca ii is neutralized jelo.
Полученные при первом электролизе осад:;и используютс в качестве ааодов второго электролиза, в результате которого получаетс кобачьт , Г1)акт ;чески свободный от . Второй электролиз проводитс при рМ 5-6 раствора и введении в электрол ;т буферных добавок и г,ро1юд 1цих солей.The sieges obtained during the first electrolysis are:; and used as aodes of the second electrolysis, which results in cobacht, G1), which is free from. The second electrolysis is carried out with a pM 5-6 solution and the addition of buffer additives and r, 1 × salts to the electrolyte.
Во избежание накоплени никел в электролите, ои удал етс осаждеиием диметилглиоксимом, который в электролит в виде суепеизии .In order to avoid accumulation of nickel in the electrolyte, it is removed by precipitation with dimethylglyoxime, which is in the electrolyte in the form of creeping.
р-1ейтрализацн образующейс при это.м свободной серной кислоты производитс добавлением щелочи, осиовиых ил: углекислых соединений НЛП гидрата окиси кобальта.The p-1 neutralization resulting from this. of free sulfuric acid is produced by the addition of alkali, axis sludge: carbonic compounds of NLP cobalt oxide hydrate.
Дл предотвращени растрескивани катод -:ого осадка избыток д :метилглиоксима удал етс обработкой электролита активированным углел5.In order to prevent cracking of the cathode -: th precipitate, excess g: methylglyoxime is removed by treating the electrolyte with activated carbon 5.
Осадок диметилглиоксима никел регенерируетс обработкой его дес ти-п тнадиати процентной серной кислотой при нагревании и при перелшщивани: . При этом получаетс свободный диметилглиоксим, возвра1цающн1 с в производство, и чистый сернокислый никель, из которого Электролизом получаетс химически чистый никель.The dimethylglyoxime nickel precipitate is regenerated by treating its ten-pnadiaty with percentage sulfuric acid when heated and under refluxing:. This produces free dimethylglyoxime, returning to production, and pure nickel sulphate, from which electrolysis produces chemically pure nickel.
