Journal ArticleDOI
Recycling of spent lithium-ion battery cathode materials by ammoniacal leaching
Heesuk Ku,Yeojin Jung,Minsang Jo,Sanghyuk Park,Soo-Kyung Kim,Dong-Hyo Yang,Kang-In Rhee,Eung-Mo An,Jeongsoo Sohn,Kyungjung Kwon +9 more
TL;DR: Co recovery via the ammoniacal leaching is believed to gain a competitive edge on convenitonal acid leaching both by reducing the sodium hydroxide expense for increasing the pH of leaching solution and by removing the separation steps of Mn and Al.
Journal ArticleDOI
Preparation of Mn−Zn ferrite from spent zinc-carbon batteries by alkali leaching, acid leaching and Co-precipitation
TL;DR: In this article, the treatment of spent zinc-carbon batteries for the recovery of valuable metals followed by conversion to Mn−Zn ferrite has been conducted employing two-stage alkali and acid leaching and co-precipitation method.
Journal ArticleDOI
Preparation of Ultra-High Purity Cylindrical Mo Ingot by Electron Beam Drip Melting
TL;DR: In this paper, a cylindrical Mo ingot with ultra-high purity was obtained by electron beam (EB) drip melting process using a Mo rod as a bar feeder was prepared from Mo powder by vacuum sintering and swaging processing.
Journal ArticleDOI
