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

This research is concerned with the bioleaching of chalcopyrite (CuFeS\(_2\)) by Thiobacillus ferrooxidans (ATCC 19859), which has been carried out in shake flasks (250 ml) and a 4-litre stirred tank bioreactor. The effects of experimental factors such as initial pH, particle size, pulp density and shake flask speed have been studied in shake flasks by employing cell suspensions in the chalcopyrite concentrate with the ATCC 64 medium in the absence of added ferrous ions. The characterisation of T. ferrooxidans on chalcopyrite concentrate was

From laboratory tests, it was concluded that relatively elevated temperatures would be required in order to achieve sufficiently fast copper leach kinetics from the hypogene ore of the Darehzar Mine in Iran, to make its mining and heap leaching economically feasible. By mathematical modelling, it was concluded that certain blends of the hypogene and supergene ore would be amenable to heap bioleaching. This provided an opportunity for the application of the techniques that were under development at Mintek at the

The main focus of this collection of peer-reviewed articles is the role that micro-organisms play in the treatment of minerals, metals, coal, oil, waste materials; and also in related environmental issues. Nowadays, as well as developing new technologies for the production of raw materials and useful products, major efforts have to be directed at the remediation of former mining sites and at environmental protection tasks associated with the various kinds of mining.

Biomining uses microorganisms to recover metals, in particular copper and gold, from ores and concentrates. This book takes a strong applied approach to the study of biomining. It describes emerging and established industrial processes, as well as the underlying theory of the process, along with the biology of the microorganisms involved. Chapters have been contributed by experts from leading biomining companies, consultants and internationally recognized researchers and academics.

The focus of this paper is on the treatment of low-grade chalcopyrite-pyrite containing concentrates. The bioleaching of chalcopyrite is a major challenge due to slow copper leach kinetics and poor copper extractions. Bioleaching tests were carried out in bench-scale piloting facilities, comprising fully controlled multi-stage continuously operated reactor systems using moderate thermophile and thermophile consortia under both uncontrolled and controlled redox potential conditions. Bioleaching operating conditions and control strategies have been identified, which have the potential to significantly increase the
