Metal Recovery of Discarded Stacks and Batteries, Liquid-Liquid Extraction and Stripping Parameters Effect

Abstract

The purpose of this paper is to study metal separation from a sample composed of a mixture of the main types of spent household batteries, using a hydrometallurgical route, evaluating the parameters effect of the liquidliquid extraction, with Cyanex 272, and stripping. The preparation of solution consisted of: grinding the waste of mixed batteries, reduction and volatile metals elimination using electric furnace and acid leaching. With the best results obtained after liquidliquid extraction and stripping it was possible to get 4 solutions of metal sulfates that they could be used in posterior metals recovery by electroplating, they are: 1) to copper recovery: Cu 203.7 g L-1+ Co 20.8 g L-1+ Mn 2,626.6 g L-1; 2) to cobalt recovery: Co 364.0 g L-1; to manganese recovery: Mn 49,929.0 g L-1and 4) to nickel recovery: Ni 1,241.9 g L-1.

Recycling of Rechargeable Batteries: Insights from a Bibliometrics‐Based Analysis of Emerging Publishing and Research Trends

“…In 2012, LIBs grew rapidly and gradually surpassed other types of batteries, which was attributed to the fact that LIBs gradually became the preferred power batteries for new energy vehicles. [ 52 ] Therefore, the value of its precious metals promoted the research progress of LIBs’ recycling technology. In addition, the number of literature on the recovery of waste Ni–Cd batteries was very small.…”

“…In 2012, LIBs grew rapidly and gradually surpassed other types of batteries, which was attributed to the fact that LIBs gradually became the preferred power batteries for new energy vehicles. [52] The related literature mainly included two aspects: recovery technology research (711 papers) and recovery benefit and status analysis (169 papers). The recycling technology mainly includes pretreatment, [53] valuable metal recovery, [54] reuse, and comprehensive utilization of resources.…”
