Jin-lan Xia,Yi Yang,Huan He,Huan He,Chang-li Liang,Xiao-juan Zhao,Lei Zheng,Chen-yan Ma,Y. B. Zhao,Zhen-yuan Nie,Guanzhou Qiu +10 more
TL;DR: In this paper, the surface sulfur speciation of chalcopyrite leached by moderately thermophilic Sulfobacillus thermosulfidooxidans was investigated by employing scanning electron microscopy (SEM), X-ray diffraction (XRD) and sulfur K-edge Xray absorption near edge structure spectroscopy (XANES), accompanying with the leaching behavior elucidation.

Comparative study of S, Fe and Cu speciation transformation during chalcopyrite bioleaching by mixed mesophiles and mixed thermophiles
Hong-chang Liu,Hong-chang Liu,Jin-lan Xia,Zhen-yuan Nie,Li-zhu Liu,Lei Wang,Chen-yan Ma,Lei Zheng,Y. B. Zhao,Wen Wen +9 more
TL;DR: In this article, the results showed that the chalcopyrite dissolution could be significantly promoted by these mixed cultures, and the promotion effects were enhanced with the increase of bioleaching temperature.
