The objective of this study is to describe primary lithium production and to summarize the methods for combined mechanical and hydrometallurgical recycling of lithium-ion batteries (LIBs). This study also aims to draw attention to the problem of lithium losses, which occur in individual recycling steps. The first step of hydrometallurgical …

The current literature reviews several processing aspects to address the extraction of nickel from laterite ore through hydrometallurgical routes. The following conclusions are summarized: Nickel is associated with cobalt in laterite oxide ores, and all the other Ni-based byproducts derive from Mg content.
