廢棄되는 黃酸鹽 試料를 處理한 結果
1. 이 試料는 主로 NiSO₄와 FeSO₄의 黃酸鹽이었으며 이들은 750℃에서는 α-Fe₂O₃만 X-線으로 確認되고 1,000℃에서는 NiO와 Fe₃O₄가確認되었다.
2. 黃酸鹽 溶液中의 鐵을 除去하기 위해서 酸化시켜 加水分解한 結果 pH 3~4.5에서 鐵이 赤褐色의 水酸化鐵로 加水分解가 되었고 이때 水酸化鐵中에 含有되어 있는 Ni은 1.2%에 달했다.
3. Eluent LIX-64N을 溶液의 부피와 대등한 부피를 취해서 Ni과 Cu를 抽出했을 경우의 pH는 7以上에서 抽出이 잘 되었고 pH 8.5~10까지의 條件에서 Resine을 處理했을 경우에 Raffinate中에 Ni 含量은 1.2gr/ℓ 程度 存在했으며 Extraction rate는 約 98%에 달했다.

다국어 초록 (Multilingual Abstract)

The following results have been obtained by treating samples of used sulfate.
(1) The X-ray diffraction analysis has shown that this sulfate sample consisting mainly of NiSO₄ and FeSO₄ gives α-Fe₂O₃ at 750℃ and produces NiO and Fe₃O₄ at 1,000℃.
(2) When the sample is oxidized and then hydrolysed to remove iron in a solution of sulfate, it has been found that iron turns into reddish-brown hydroraded iron. When this occurs, the Ni content of hydrated iron has reached 1.2％.
(3) It has been shown after taking eluent LIX-64N the volume of which is equivalent to the volume of solution that the extraction for Ni and Cu can be done effectively at pH values of 7 or more and that under that condition of pH range from 8.5 to 10 the Ni content of raffinate is about 1.2gr/ℓ, when resine is treated, and extraction rate has been obtained to be nearly 98％.
