박용성,우제원,황영애 한국자원리싸이클링학회 2000 資源 리싸이클링 Vol.9 No.6
본 연구는 폐 망간전지의 음극합체로부터 Mn성분을 분리 회수할 수 있는 새로운 공정개발을 위하여 폐 망간전지의 음극합체와 황산암모늄과의 분해반응을 조사하였다 최적 분해반응 조건은 반응온도 $425^{\circ}C$, 폐 망간전지의 음극합체에 대한 황산암모늄의 무게비 12.0, 반응시간 60분이었고, 이 조건에서 얻어진 Mn의 최고 회수율은 93.5%였다. A reaction between the depolarizing mixture in the spent manganese batteries and ($NH_4$)$_2$$SO_4$was carried out to find a new process for the extraction of Mn component from the spent manganese batteries. The optimum conditions were as follows : the reaction temperature $425^{\circ}C$, ($NH_4$)$_2$$SO_4$weight ratio to the depolarizing mixture in the spent manganese batteries 12.0, reaction time 60 min. Under above conditions manganese was extracted 93.5%.

Recently an algorithm known as the complementary pivot algorithm has been developed for solving LCPs. Computational experience on this new algorithm is limited, but indicates that it may be superior to the symplex method for solving LPs. The new algorithm has the addi-tional advantage that it can also solve quadratic programs and bimatrix game problems. hence the theory of the LCP serves as a unified theory for studying linear and quadratic programs and bimatrix games. Here we discuss the main results in the quadratic programs. That is:
