- Industrially inexpensive and useful since particles are generated and grown from an aqueous solution by a wet reaction, a large number of crystal nuclei are generated non-uniformly and the growth is hindered in the same manner as each of the prior arts described above. There is. In other words, it is indispensable to control the number of derived crystal nuclei within an appropriate range for efficient growth.
- a method is generally used in which a reducing agent is supplied to a slurry in which a small amount of fine crystals called seed crystals coexist and a target product is grown on the surface of the seed crystals to obtain a powder having a predetermined particle size.
- the seed crystals added in the above are often used after being subjected to a treatment such as pulverizing a part of the product repeatedly.
- a treatment such as pulverizing a part of the product repeatedly.
- the optimum grain size and properties of the seed crystal cannot always be obtained simply by pulverization. That is, a method for stably obtaining a seed crystal used for crystal growth has been demanded.
- the present invention provides a production method for efficiently obtaining cobalt powder by a method for increasing the reduction reaction efficiency in producing cobalt powder from a solution containing a cobalt ammine sulfate complex.
- the first invention of the present invention that solves such problems is to add a solution containing a cobalt sulfate ammine complex by adding ammonia, an ammonia compound solution, or both ammonia and an ammonia compound solution to a cobalt sulfate solution.
- a complexing step to be obtained, a mixing step in which a solid is added to the solution containing the cobalt ammine sulfate complex obtained in the complexing step to form a mixed slurry, and the mixed slurry obtained in the mixing step are placed in a reaction vessel.

- cobalt powder is obtained by passing the cobalt sulfate solution used as an original liquid through a complexing process, a mixing process, a reduction / precipitation process, and a solid-liquid separation process.
- the reduction rate as used in the field of this invention was defined by the ratio which remove
- the cobalt sulfate solution that can be used in the present invention is not particularly limited, but is a kind selected from cobalt and cobalt-containing mixed sulfide, crude cobalt sulfate, cobalt oxide, cobalt hydroxide, cobalt carbonate, cobalt powder, and the like, Alternatively, a cobalt leaching solution obtained by leaching and dissolving a cobalt-containing material such as an industrial intermediate composed of a plurality of mixtures with sulfuric acid or ammonia can be used.

- the cobalt concentration in the cobalt sulfate ammine complex solution is 75 g / L or less. This is because, when adding and reacting a solid in the subsequent step, if the cobalt concentration in the cobalt sulfate ammine complex solution is too high, the reaction field is insufficient and the reduction rate is lowered.

- nickel powder When cobalt powder is used as a solid substance, it is the same as cobalt precipitate, so it is not necessary to peel them off in the subsequent process and is optimal for use as a seed crystal, but industrially fine cobalt powder is inexpensive and stable. It is difficult to obtain.
- Iron powder has the advantage of being inexpensive and easily available, but has the disadvantage of being easily dissolved in an acidic solution and difficult to form crystal nuclei. Also, the dissolved iron ion is not suitable because it causes new contamination. Also, in the method of depositing cobalt on a hardly soluble or insoluble solid as in the present invention, a method of depositing cobalt using a seed crystal that has been conventionally used to produce a product together with the seed crystal. Unlike the process, the effect of redissolving is negligibly avoided and there is no need to repeat a part of the product, so that the cobalt complex ions contained in the ammine complex solution can be reduced almost completely in terms of the process quantity balance. There are features that can be done.

Abstract
Description
これらのコバルト塩類は、コバルトメタルを酸に溶解して製造することが一般であるが、従来から一般的な電気コバルトなどシートや塊状の形態は取扱いしやすいものの酸への溶解が極端に遅く、一方で微粉末の形状は、酸には溶解しやすいものの飛散しやすいなど取扱いに難があり、両者の長所を生かすためにブリケットと呼ばれる粒ないし粉末を圧密あるいは焼結して得たものが好まれている。
しかし、これらの方法は高価な試薬類や多量のエネルギーを必要とするため、上記の電池材料など大量の物量を工業的に得る方法としては経済的ではない。
けれども、この方法でも、湿式反応により水溶液中から粒子を発生させ成長させようとすることから、上記の各先行技術と同じように不均一に多数の結晶核が発生し、成長が阻害される課題がある。つまり派生する結晶の核の数を適正な範囲に制御し、効率よく成長させることが欠かせない。
そこで前述したように種結晶と呼ばれる微細な結晶を少量共存させたスラリーに還元剤を供給し、種結晶の表面に目的物を成長させ所定の粒径の粉末を得る方法が一般に用いられている。
すなわち結晶成長に用いる種結晶を安定して得る方法が求められていた。
なお、本発明でいう還元率は、得たコバルト粉の重量(g)を、供給した硫酸コバルト溶液(L)中に含有されるコバルト物量(g/L)で除した割合で定義した。
本発明で用いることのできる硫酸コバルト溶液は、特に限定はされないが、コバルトおよびコバルトを含有する混合硫化物、粗硫酸コバルト、酸化コバルト、水酸化コバルト、炭酸コバルト、コバルト粉などから選ばれる一種、または複数の混合物から成る工業中間物などのコバルト含有物を、硫酸あるいはアンモニアにより浸出・溶解して得たコバルト浸出液を用いることができる。なお、工業的には上記のコバルト浸出液には様々な不純物も含有されるのが普通であり、上述の浸出液は溶媒抽出法、イオン交換法、中和などの浄液工程を施すことにより浸出液中の不純物元素を除去して用いることが一般である。
なお、溶液中の硫酸アンモニウム濃度は10~500g/Lの範囲とすることが好ましい。500g/L以上の濃度にすると、溶解度を超えてしまい結晶が析出する場合があり操業上のトラブルを生じるので好ましくない。また、10g/L未満の濃度は反応により硫酸アンモニウムが新たに生成するため、工業的に10g/L未満は困難である。
また、硫酸コバルトアンミン錯体溶液でのコバルト濃度は75g/L以下の濃度とする。これは、後工程で固形物を添加して反応させる際に、硫酸コバルトアンミン錯体溶液中のコバルト濃度が高すぎると反応場が不足して還元率が低下するためである。
この工程では、上記で作製された硫酸コバルトアンミン錯体溶液に、析出の母体となる固形物を添加する。
添加する固形物は、硫酸コバルトアンミン錯体溶液、硫酸アンモニウム水溶液或いはアルカリ溶液に対して不溶、若しくは溶解度が小さい難溶なものであれば、特に限定はない。
コバルト粉を固形物に用いると、コバルト析出物と同一なので、後工程でこれらを引き剥がす必要がなく、種晶として用いるには最適であるが、工業的に微細なコバルト粉を低価格かつ安定して入手することは困難である。
また本発明のように難溶ないし不溶性の固形物を用いて、その上にコバルトを析出させる方法では、従来一般に使われてきた種結晶を用いてコバルトを析出させ、種結晶ごと製品とする方法と異なり、再溶解の影響を無視できるほど避けられ、製品の一部を繰り返す必要もないので、プロセスの物量バランス上ではアンミン錯体溶液中に含有されるコバルト錯イオンをほぼ完全に還元する事が出来る特徴がある。
次に、混合工程でニッケル粉を添加して形成したスラリーを、圧力容器の反応槽内に装入し、その反応槽内に水素ガスなどの還元剤を吹き込み、そのスラリー中のコバルト錯イオンを還元し、前記の固形物の表面にコバルトを析出させる。
なお、水素ガスは反応槽内の気相部に吹き込んでもスラリー中に直接吹き込んでもいずれでも構わない。
還元・析出工程で得た表面にコバルト析出物を有する固形物を、圧力容器内の還元後液と共に圧力容器から取り出し、還元後液と固液分離する。
この固液分離は、例えばヌッチェと濾瓶を使う方法や、遠心分離機を用いる方法、フィルタープレスを用いる方法などいずれでも構わない。
具体的に分離する方法は、固形物とコバルト析出物に衝撃を与えるなど適宜おこなうことができる。
また、ここで回収した固形物は再度上記混合工程に繰り返して使用することができる。
還元後液は、そのままあるいは加熱・蒸留等の処理によってアンモニアに再生し、前記錯化工程の錯化剤として繰り返し使用することができる。
なお、平均粒径は市販のレーザ回折・散乱式粒子径分布測定装置(マイクロトラック)を用いて測定した。
この溶液に、析出母体となる粒径1μmのニッケル粉75gを添加して混合スラリーを得た。
このときのコバルトの還元反応率は99%であった。
コバルト75gと硫酸アンモニウム330gと25%アンモニア水を191ml含む溶液を得、これに本発明の種結晶の固形物の代わりに、濃度40wt%のポリアクリル酸3.73gを分散剤として添加し、合計の液量が1000mlになるように調整して、硫酸コバルトアンミン錯体を含有する溶液を作製した。
この溶液に、析出母体となるコバルト粉75gを添加して混合スラリーを作製した。
水素ガスの供給から60分が経過した後に水素ガスの供給を停止し、内筒缶を冷却した。
コバルト75gの硫酸コバルト溶液に、硫酸アンモニウム330gを含む溶液に25%アンモニア水を191ml、合計の液量が1000mlになるように調整して、硫酸コバルトアンミン錯体を含有する溶液を作製した。
この溶液に、この溶液に溶解する固形物として市販の平均粒径1μmの鉄粉75gを添加して混合スラリーを作製した。
