초록

본 연구는 심해저 망간단괴(deep sea manganese nodule)를 황산암모늄으로 분해 침출시킨 모액으로부터 코발트, 니켈, 구리의 효과적인 분리 회수를 위해 Mn 및 Fe 성분의 산화침전에 의한 우선적인 분리 제거와 액막법에 의한 코발트, 니켈, 구리의 선택적인 분리를 시도하였다. 과황산 암모늄(ammonium persurlfate)을 산화제로 하여 pH 9.0 ~ 9.8 의 조건에서 산소를 통과시키며 용액중 Mn은 99.97% Fe성분은 99.84%를 침전제거시킬 수 있었다. 코발트, 니켈, 구리의 액막법에 의한 분리의 시도에서는 추출담체를 D2EHPA(5% 용액), 계면활성제 span80 3% 용액(kerosene을 회석제로 하여)으로 만든 용액과 황산수용액(150 g/l)을 1 : 1의 부피비로 혼합하여 막강화제 paraffin oil 20%를 가해 에멀젼을 제조하였다. 이 에멀젼을 이용하여 외부수용액에 음이온계면활성제 아세트산나트륨 0.03 mol/l를 가하여 분리추출하였으며 pH 2.5에서 Cu가 Co 및 Ni 성분과 선택적으로 분리가능하며 pH 5.0에서 Co와 Ni가 효과적으로 선택분리가 됨을 나타내었다.

The recovery process of valuable metal components such as Cu, Ni and Co from the leachate of deep sea manganese nodule was investigated. This process consists of Mn and Fe removal using the oxidation-precipitation and the selective separation of Cu, Ni and Co by the liquid membrane. 99.9% of Mn and 99.8% of Fe component in the leachate were removed from the leachate of manganese nodule nuder the condition, such as pH condition range from 9.0 to 9.8, adding 1 M ammonium persulfate in the atmosphere of air flow. Emulsion was prepared by 5% D2EHPA, 3% span 80 with kerosene and organic solution added to 150 g/l of H2SO4 solution was mixed by 1:1, then adding to 20%. Using this emulsion, selectively extracted added 0.03 mole/l sodium acetate. Cu component was selectively separated from Co and Ni components at pH 2.5, and Co and Ni component was effectively at pH 5.0.

Keywords:manganese nodule;emulsion;leaching;selective extract;valuable metal
