Nickel (Ni) and cobalt (Co) are strategic metals that have found applications in a wide range of metallurgical and industrial uses. In this study, the dissolution of a mixed nickel–cobalt hydroxide precipitate using organic acids (citric, oxalic, and malic acid) was investigated. Citric acid was found to be the best leaching agent yielding the following …

Instead, they looked at cobalt mining in Australia, where cobalt is removed as a byproduct of copper and nickel extraction. Even though mining in Australia is highly regulated, Huda and colleagues found that this method of cobalt extraction comes with a hefty environmental price tag — mainly because of the greenhouse gas emissions …

Lithium-ion batteries (LIBs) deployed in battery energy storage systems (BESS) can reduce the carbon intensity of the electricity-generating sector and improve environmental sustainability. The aim of this study is to use life cycle assessment (LCA) modeling, using data from peer-reviewed literature and public and private sources, to …

Combining two or three extraction reagents has also been reported, but these co-extraction methods not only complicated the cobalt extraction process, 10,18,28,29 but also reduced phase separation efficiency, thereby increasing stability of cobalt–nickel extract (i.e., reducing stripping rate), which requires the use of acids with high ...
