A copper-catalyzed bioleaching process was developed to recycle cobalt from spent lithium-ion batteries (mainly LiCoO 2) in this paper. The influence of copper ions on bioleaching of LiCoO 2 by Acidithiobacillus ferrooxidans ( A.f) was investigated.

Elemental Copper Recovery from e-Wastes Mediated with

2020-3-27 Abstract Copper recovery from printed circuit boards (PCB) from waste mobile phones was investigated using a two-step bioleaching process. The method consists of a first step where Fe(II) ions are biologically oxidised to Fe(III) by Acidithiobacillus ferrooxidans. Later, Fe (III) ions are put in contact with the PCBs for copper solubilisation. At the conditions tested in the present work, the

Bioleaching of copper, nickel and cobalt from the low

2015-4-1 The results showed that 55.0% of copper, 98.2% of nickel and 59.5% of cobalt could be extracted from the tailing through the bioleaching process after 30 days at 5% (w/v) pulp density. The recovery of valuable metals from the tailing in the presence of microorganisms was approximately three times higher than that in the un-inoculated leaching

Bioleaching of copper from waste printed circuit boards by

2018-2-22 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, copper extraction from PCBs was investigated using bacteria-free cultural supernatant from some metallurgical microbial consortium, whose predominant organisms were Leptospirillum ferriphilum and Sulfobacillus

Bioleaching (Biomining) Advantages, Process & More

How does the bioleaching process work? There are many types of bioleaching processes, and copper is the most common. A few of the most popular types of bioleaching extract metals from ore by retrieving sulfide minerals using bacteria that receive energy from non-carbon compounds.

Bioleaching of copper sulfide minerals assisted by

A proof-of-concept of copper sulfide mineral bioleaching assisted by microbial fuel cells (MFCs) was demonstrated in current study. Simultaneous copper extraction and electricity generation were obtained in this bioleaching process, providing a novel approach for copper sulfide mineral bioleaching.

Mission 2015: Bioleaching Massachusetts Institute of

2011-12-1 The process can be used on ores that are only 0.5 to one percent copper, too little for conventional refining. The solution is then drained in to an electrolytic cell and copper extracted from it. In addition, studies show that zinc, nickel and cobalt can also largely be extracted by the process of bioleaching

How does the bioleaching process work? AnswersToAll
