Abstract

The methods to separate and remove copper in the mixed solution ((399 ppm Cu, 208 ppm Fe, 15.3 g/L Ni, 2.1 g/L Co) with nickel, cobalt and iron were investigated. With hydroxide precipitation method, copper and iron ions were completely precipitated and removed from the solution at pH 7 while some nickel and cobalt also were precipitated. 99.75% copper could be precipitated and removed as copper sulfide from the solution with adding $Na_2S$ (1.25 w/v concentration) of 2 times equivalent of Cu at pH 1. Copper was selectively absorbed on TP 207 ion exchange resin at equilibrium pH 2.0 and could be eluted from copper-loaded resin using 5% $H_2SO_4$.

니켈, 코발트와 철의 혼합용액에 미량 함유되어 있는 구리 (399 ppm 구리, 208 ppm 철, 15.3 g/L 니켈, 2.1 g/L 코발트)를 분리, 제거를 위한 방법들을 검토하였다. 중화침전법의 경우 용액의 pH가 7.0 에서 구리는 철과 함께 전부 수산화물로 침전, 제거되었으나 니켈과 코발트의 일부도 함께 침전되었다. 황화침전법의 경우 1.25% 농도의 $Na_2S$를 구리의 2당량비 첨가하고 용액의 pH가 1.0인 경우 구리가 99.7% 제거 되었다. TP207 양이온 흡착제를 사용한 이온교환수지법은 평형 pH 2.0 에서 구리만이 선택적으로 흡착되었으며 탈착용액으로는 5% 황산이 적당하였다.
