Biohydrometallurgy of Chalcopyrite (eBook)

Bioleaching of chalcopyrite is always a challenge and research hotspot. The low copper extraction and dissolution kinetics restricted the industrial application of chalcopyrite bioleaching. To solve this problem, the dissolution process and passivation mechanism of chalcopyrite in bioleaching should be first studied, then the rate-limiting steps should be analysed explicitly, and finally the intensifying method can be put forward. Many scholars have made efforts to investigate the dissolution mechanism of chalcopyrite in bioleaching. However, there is no congruence of opinion as yet. Biohydrometallurgy of Chalcopyrite summarizes and discusses the reported research findings. In addition, this book publishes the related results found by the authors' research. Then, the dissolution mechanism of chalcopyrite in bioleaching is interpreted. Finally, the process intensification techniques of chalcopyrite bioleaching are provided and discussed. Hence, this book provides useful reference and guidance in both laboratory research and industrial production.

• Interprets the dissolution mechanism of chalcopyrite in bioleaching
• Provides feasible technologies for intensifying chalcopyrite bioleaching
• Overviews the current situations of chalcopyrite bioleaching
• Helps the readers to deeply understand the bioleaching mechanisms of chalcopyrite
• Provides topics for future research and potential industrial applications

Prof. Hongbo Zhao (1988. 09-) obtained his BSc, MSc and PhD degrees from Central South University in Changsha, China. He studied in the Talented Student Class of Chemistry (Honor Class of Chemistry) at Central South University between 2008 and 2012. He then commenced his PhD studies, instructed by Professor Guanzhou Qiu, in 2012 and obtained his doctoral degree in Minerals Processing Engineering in 2016. Since 2016, he has been working at Central South University as an associate professor. His researches mainly focus on Mineral processing and extractive metallurgy (Resource recovery), Biohydrometallurgy, Bioremediation, Environmental chemistry, Biogeochemistry and Electrochemistry. Prof. Zhao has more than 30 publications as the first author/corresponding author, of which more than 20 publications were indexed by SCI, and one monograph. Prof. Zhao has applied for 15 patents, and 7 have been authorized. Prof. Zhao is now presiding over 6 research projects, and has obtained many awards, such as the Young Elite Scientists Sponsorship Program supported by CAST (2017-2019) and 15th Excellent Natural Science Paper of Hunan Province, etc. Prof. Zhao is now serving as the associate editor of Chemie der Erde-Geochemistry (SCI, IF=1.723), editor of Frontiers in Microbiology (SCI, IF=4.019), editor of Plos one (SCI, IF=2.766), guest editor of Minerals & Metallurgical Processing (SCI, IF=1.714), the advisory editor of Cambridge Scholars Publishing, the committee member of the Committee of Comprehensive Utilization of Metallurgical Resources, and the committee member of the Industrial Alliance of Nonferrous Metals of China, etc. Prof. Zhao is serving as the reviewer of more than 20 SCI indexed journals, such as Journal of Hazardous Materials, ACS Sustainable Chemistry & Engineering, Electrochimica Acta and Hydrometallurgy, etc. In addition, Prof. Zhao has rich practical experiences in the mining and metallurgical industries.
