Recent Advances in Recycling of Copper‐Based Waste Materials: A Critical Review

open access: yescMat, Volume 2, Issue 2, June 2025.
ABSTRACT Copper plays a crucial role in the civilization of our lives. This review examines the flow of copper from the mining of ores to the end‐of‐life product, with particular emphasis on the recovery and re‐functionalization of copper and copper‐containing wastes. Beginning with the analysis of the global copper market, reserves, supply, and demand,

Cytochromes in anaerobic growth of Acidithiobacillus ferrooxidans

open access: yesMicrobiology, 2018
The mineral sulfide-oxidising Acidithiobacillus ferrooxidans has been extensively studied over many years but some fundamental aspects of its metabolism remain uncertain, particularly with regard to its anaerobic oxidation of sulfur. This label-free, liquid chromatography-electron spray ionisation-mass spectrometry-based proteomic analysis estimated ...

Properties of realgar bioleaching using an extremely acidophilic bacterium and its antitumor mechanism as an anticancer agent

open access: yesBiological Research, 2017
Realgar is a naturally occurring arsenic sulfide (or Xionghuang, in Chinese). It contains over 90% tetra-arsenic tetra-sulfide (As4S4). Currently, realgar has been confirmed the antitumor activities, both in vitro and in vivo, of realgar extracted using ...
