As more renewable energy is developed, energy storage is increasingly important and
attractive, especially grid-scale electrical energy storage; hence, finding and implementing …

The main aim of this paper is to review and evaluate the recovery studies and associated
technologies for metals from spent batteries. More attention was given especially to the …

Acid leaching for different types of mixed spent Li-ion mobile batteries is carried out after
alkali decomposition using NH 4 OH followed by H 2 SO 4+ H 2 O 2 leaching. In the alkali …

This work describes a hydrometallurgical process to recover rare earth and basemetals from
spent NiMH batteries. Laboratory tests were conducted by using NiMH powders obtained in …

Research on biohydrometallurgy of secondary metal resources is primarily focused on the
leaching of valuable metals. For secondary metal resources biological processing can be an …

In this paper a recycling process for the recovery of zinc and manganese from spent alkaline
and zinc–carbon batteries is proposed. Laboratory tests are performed to obtain a purified …

The main objective of this study was to investigate the effects of reductive acidic leaching
and further precipitation on the recovery of manganese and zinc from spent alkaline and …

The aim of this review paper is to critically analyze the existing studies on waste electric and
electronic equipment (WEEE), which is one of the most increasing solid waste streams. This …

The global consumption of manganese is rising due to its growing industrial requirement
while the natural reserves of manganese are diminishing at an alarming rate. Consequently …

Abstract Acidothiobacillus ferrooxidans (A. ferrooxidans), an iron-oxidizing bacteria oxidizes
Fe (II) to Fe (III), which is an excellent leaching agent to leach out rare earth elements …
