Co precipitatesとは 意味・読み方・使い方

Further, the remaining precipitates after the recovery are washed with water by an amount of one or more times, and Ni and Co in the remaining precipitates are further recovered.例文帳に追加

また、回収後の残沈殿物を１倍量以上の水で洗浄し、残沈殿物中のＮｉとＣｏを更に回収する。 - 特許庁

When Ni and Co are recovered from the iron precipitates, the iron precipitates are crushed to the size of ≤1/3 of the bottom area of a reaction tank, and the concentration of Ni in a reaction solution is controlled to ≤35 g/l.例文帳に追加

鉄沈殿物からＮｉとＣｏを回収する際に、鉄沈殿物の大きさを反応槽の底面積の１／３以下に粉砕とし、及び反応液のＮｉ濃度を３５ｇ／ｌ以下とする。 - 特許庁

In a treatment method for dissolving the Co precipitates containing at least hydroxides of Co and Fe, with an acid, this method is characterized by dissolving a part of or substantially all of Co into a treatment liquid, while substantially leaving Fe in the precipitates as in solid state, by varying pH of the treatment liquid in a range of 0.5-3.0.例文帳に追加

少なくともＣｏおよびＦｅの水酸化物を含有するＣｏ沈殿物を、酸により溶解する処理方法において、処理液のｐＨを０．５以上３．０以下の範囲内で変化させることにより、Ｆｅを沈殿物中に固体の状態で実質的に残したまま、Ｃｏの一部または実質的に全部を、処理液中に溶解する。 - 特許庁

To selectively and efficiently recover valuable metals such as Ni and Co from a raw material solution in which a nickel mat or the like are eluted by converting impurities such as iron and copper into iron precipitates and suppressing the elution of copper from the iron precipitates.例文帳に追加

ニッケルマットなどを溶出した原料溶液から鉄や銅などの不純物を鉄沈殿物とし、その鉄沈殿物から銅の溶出を抑えつつ、Ｎｉ及びＣｏなどの有価金属を選択的且つ効率的に回収する。 - 特許庁

The pH of the raw material solution is controlled in two steps to 2.5 to 3.5 in the first step and to 4.5 to 5.5 in the second step, and sulfuric acid is added to the obtained iron precipitates, and stirring is performed to selectively elute and recover Ni and Co into sulfuric acid.例文帳に追加

原料溶液のｐＨを第１段階で２.５〜３.５、第２段階で４.５〜５．５に２段階調整し、得られた鉄沈殿物に硫酸を加えてｐＨ３.０〜４.０で攪拌することにより、ＮｉとＣｏを選択的に硫酸中に溶出回収する。 - 特許庁
