LiBs pose a very specific threat, given that they contain a high percentage of dangerous
heavy metals. From the 4000 t of used lithium-ion batteries collected in 2005, 1100 t of …

The need to process low-grade and/or complex chalcopyrite-containing ores that cannot be
concentrated is the main driver for the development of hydrometallurgical processes. The …

Environmental pollution by heavy and toxic metals because of mining, metallurgic
processes, and other chemical industries is a worldwide problem affecting both human …

The present understanding of the surface chemistry of acidic ferric sulphate dissolution of
chalcopyrite is critically reviewed with regard to hindered dissolution and how the …

A copper-catalyzed bioleaching process was developed to recycle cobalt from spent lithium-
ion batteries (mainly LiCoO2) in this paper. The influence of copper ions on bioleaching of …

Bioleaching is considered to be a low-cost, eco-friendly technique for leaching valuable
metals from a variety of matrixes. However, the inherent slow dissolution kinetics and low …

This review addresses the recovery of metals from all the main types of spent batteries
(including Li-based, Zn-based, and Ni-based batteries) using bioleaching processes …

The influence of silver ions (Ag+) on the bioleaching of cobalt from spent lithium batteries
using Acidithiobacillus ferrooxidans (A. ferrooxidans) bacteria was investigated. The best …

Recovery of metal values from sulfide ores by use of acidophilic microorganisms is gaining
importance. A number of commercial/pilot plants are setup to find out the techno-economic …

The ability of an extreme thermophile to oxidise a concentrate comprising of chalcopyrite
(66%) and pyrite (11%) is described. A batch test at 70° C showed that a copper extraction …
