In this study, we attempted to separate and recover Cu from low-grade copper ore by a hydrometallurgical process. The leaching sample obtained after crushing and sieving by 0.355 mm of low-grade copper ore contained 1.5% Cu, 4.7% Fe, 1.0% Mn, and 0.3% Zn. The Cu in the oxide ore was very well leached into sulfuric acid and 97% Cu leaching efficiency was achieved at 80℃ and 3 M sulfuric acid (H<sub>2</sub>SO<sub>4</sub>). From the leaching solution, Cu was separated by solvent extraction from Fe, Mn, and Zn using LIX984N. The separation tendency between Cu and other metals was confirmed through the distribution ratio and separation factor. By plotting the McCabe-Thiele Diagram, the optimum condition for recovering Cu is 5 vol.% LIX984N, 2-stage counter-current solvent extraction, and an O/A ratio of 0.5. Using this method, 99% of the Cu was extracted and a CuSO<sub>4</sub> solution was finally obtained that contained 1.6 g/L Cu after the stripping process using 2 M H<sub>2</sub>SO<sub>4</sub>.

There are several kinds of batteries such as zinc-air battery, lithium battery, Manganese dry battery, silver oxide battery, sodium-sulphur battery, lead acid battery, metal hydride secondary battery, nickel-cadmium battery, lithium ion battery, alkaline battery, etc. These days it has been widely studied for the recycling technologies of the used battery from view points of economy and efficiency. In this paper, patents and published papers on the recycling technologies of the used battery were analyzed. The range of search was limited in the open patents of USA (US), European Union (EU), Japan (JP), Korea (KR) and SCI journal articles from 1972 to 2011. Patents and journal articles were collected using key-words searching and filtered by filtering criteria. The trends of the patents and journal articles were analyzed by the years, countries, companies, and technologies. 전지는 공기아연리튬망간산화은나트륨-유황납축니켈-수소 이차니켈-카드뮴리튬이온알칼라인 전지 등의 여러 종류가 있다. 경제적, 효율적 관점에서 폐전지의 재활용 기술은 폭넓게 연구되어 왔다. 본 연구에서는 폐전지의 재활용 기술에 대한 특허와 논문을 분석하였다. 분석범위는 1972년~2011년까지의 미국, EU, 일본, 한국의 등록/개된 특허와 SCI 논문으로 제한하였다. 특허와 논문은 키워드를 사용하여 수집하였고, 기술의 정의에 의해 필터링하였다. 특허와 논문의 동향은 연도, 국가, 기업, 기술에 따라 분석하여 나타내었다.

In this study, the leaching behavior of vanadium (V) was investigated through CaO roasting and sulfuric acid leaching from domestic V-bearing titanomagnetite (VTM). Changes in the phase according to the amount of CaO added and roasting temperature were analyzed. Regardless of the roasting conditions, perovskite (CaTiO<sub>3</sub>) was preferred to form. When the CaO content was increased, the calcium ferrite (CaFeO<sub>x</sub>) phase was formed; otherwise, ferrite (Fe<sub>2</sub>O<sub>3</sub>) was preferred. After CaO was roasted, leaching was performed for 6 h with 1M sulfuric acid at 50℃ and a 10% solid-liquid ratio. Results of leaching revealed that when the roasted product was sintered, V was not sufficiently oxidized, and the leaching efficiency decreased. In addition, when the roasting temperature was low, the leaching efficiency of V decreased due to the influence of unreacted excess CaO. To lower the leaching efficiency of iron and titanium in VTM concentrates, suppressing the formation of CaTiO<sub>3</sub> and CaFeO<sub>x</sub> was necessary by minimizing the amount of CaO added. Consequently, a leaching efficiency of 86% V, 4.3% Fe, and 6.5% Ti was obtained when the roasted product of 1150℃ and 10 wt% CaO was leached.

본 연구는 회분식 연구에서 pilot 규모의 연속 장치를 통해 폐 혼합전지로부터 Zn과 Mn을 Ni, Fe, Cu 등으로부터 동시에 회수 및 농축하는 것을 입증하기 위해 연구하였다. Pilot 공정은 안정적 해체 및 물리적 전처리 공정, 침출공정, 용매추출 공정으로 구성되었다. 우선 안정적 해체 및 물리적 전처리 공정에서 Ni-Cd 전지, 폐-망간 알카라인 전지를 1:2의 비율로 혼합하여 Fe, Cu, Al을 약 90% 이상 제어하였고, 반면 Zn와 Mn, Ni 농축된 전지분말을 획득하였다. 이 전지분말로부터 약 10 ㎥ 규모의 침출장비를 이용하여 황산환원 침출을 통해 8.3 g/L Zn, 7.0 g/L Mn, 1.9g/L Ni을 함유한 용매추출 feed 용액을 확보하였다. 마지막으로 1단의 크기가 70 L 규모인 용매추출 장비를 이용하여 3단 추출, 3단 세정, 3단 탈거의 용매추출공정을 구성하였다. 이를 통해 Di-2-ethylhexyl phosphoric acid(D2EHPA)을 사용하여 Zn와 Mn을 25 g/L, 15.4 g/L 로 동시에 회수 및 농축시켰고 나머지 불순물의 경우 그 농도를 10 ppm 이하로 제어시켰다. 사사: 본 논문은 환경부 글로벌탑 환경기술개발사업 중 유용자원재활용기술개발사업의 지원에 의하여 연구되었으며 이에 감사드립니다(과제번호: 2016002220001).
