Compared to conventional extractive techniques, bacterial assisted leaching, also called
“biomining” is an eco-friendly technology that provides improved metal/solid separations …

The rapid pace of innovations and the frequency of replacement of electrical and electronic
equipment has made waste printed circuit boards (WPCB) one of the fastest growing waste …

The wealth of the society depends on several metals, including base metals, precious
metals and increasingly rare earth elements (REE). They are collectively termed as …

Spent lithium-ion batteries have caused global concern owing to their rich resource metal
content and high potential for polluting the environment. In the present study, a green …

An effective strategy for environmentally sound biological recovery of copper and gold from
discarded printed circuit boards (PCB) in a two-step bioleaching process was experimented …

Numerous studies have sought to address the extraction of metals from printed circuit
boards by employing bioleaching process. However, separation and recovery of the …

The pyrometallurgy coupling indirect bioleaching strategy is proposed for the recycling of
WPCBs to avoid the disadvantages of time-consuming, low processing power, and relatively …

This paper is the first study on the extraction of Cu, Ni, and Ga from Light Emitting Diode
(LED) waste by bio-hydrometallurgy technology. LEDs have a high concentration of metals …

Background The toxicity of waste printed circuit boards (PCBs) to bacteria was considered
as the major limitation in bioleaching of copper from PCBs. To reduce the toxicity of PCBs …

Many studies are now focusing on bioleaching methods to recover metals from WEEE. The
efficiency of this process is highly dependent on microorganisms but also on the solid-liquid …
