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

Biohydrometallurgy has been commercially applied for the extraction of base metals from
low-grade sulfidic ores and the pre-treatment of refractory sulfidic gold-containing minerals …

The technology for recycling the spent coin cells is pressing needed due to a large amount
of generated spent coin cells. However, there is little information about the recycling …

Nowadays, due to fast global industrial progress and near diminution of high-grade ore
reserves, there has been massive call to cost-effectively process the resources of low-grade …

Lead–zinc sulfide mine tailings without appropriate disposal would cause resource waste
and heavy metal pollution in the environment. This study aims to design a novel mixed …

Although jarosite and visible light are important factors for the formation of acid mine
drainage (AMD), the effects of combined jarosite and visible light on chalcopyrite …

The study investigated the leaching efficiency and microbial flora of an electro-assisted
biochemical cycle reactor were investigated for gold ore bio-oxidation. The results showed …

Primary copper sulfides, such as chalcopyrite, represent the most important copper resource
and are currently mainly exploited by pyrometallurgy. Bioleaching is considered as …

Chalcopyrite is the richest copper sulfide mineral in the world, but it is also the most resistant
to biohydrometallurgical processing. To promote the bioleaching of chalcopyrite, a nonionic …

Bioleaching experiments and electrochemical measurements were conducted to investigate
the effect of pyrite on bornite bioleaching by Leptospirillum ferriphilum. Bioleaching …
