Book Description :

Volume is indexed by Thomson Reuters CPCI-S (WoS). The main focus of this collection of peer-reviewed articles is biohydrometallurgy. This is the field of microbial ecology which is the key to answering central questions concerning not only the diversity and behavior of micro-organisms in commercial operations, but also possible applications in biohydrometallurgy of extremophiles coming from very different environments. The 134 papers are grouped as follows: Chapter 1: Microbial Ecology, Geomicrobiology and Bioprospecting in Natural and Mining Environments; Chapter 2: Omics, Molecular Genetics and Biochemistry of Microorganisms in Mining Processes; Chapter 3: Industrial Biohydrometallurgy: Studies, Practices and Operation; Chapter 4: Biohydrometallurgy as a Remediation Strategy.

Book Description :

Volume is indexed by Thomson Reuters CPCI-S (WoS). The main focus of this collection of peer-reviewed articles is three different aspects of biohydrometallurgy: this is the field of microbial ecology which is the key to answering central questions concerning not only the diversity and behavior of micro-organisms in commercial operations, but also possible applications in biohydrometallurgy of extremophiles coming from very different environments. This covers metal recovery bioprocesses, including basic and applied studies of bioleaching and bio-oxidation; but also bioflotation. A large part of the book is given over to interfacial studies which contribute to the understanding of the interaction between surfaces and micro-organisms during those processes. Also covered are the remediation of mining activities and environmental protection as related to mining and mining industries.

Book Description :

Chalcopyrite is known to be recalcitrant to conventional hydrometallurgical and biohydrometallurgical processes. Formation of passive layers on the chalcopyrite surface results in slow and incomplete leaching. The nature of how these passive layers are formed is the subject of much controversy. The most likely explanation is the formation of polysulphide compounds or copper-rich intermediate products on the chalcopyrite surface. The formation of these products depends mainly on temperature and solution potential. Based on these observations, electrochemical techniques were used to study the behaviour of chalcopyrite under a variety of conditions similar to ferric and microbial leaching. Electrochemical techniques have the advantage over other techniques of measuring properties at the solid-liquid interface. Slow chalcopyrite leaching was mainly observed under the following conditions: (1) low temperature (25C̕) and low potential (0.45 to 0.6 V SCE); (2) high temperature (65C̕) and high potential (above 0.6 V SCE). Leaching was accelerated at high temperature (65C̕) under mildly oxidizing conditions (0.45 to 0.55 V SCE). The study also indicated that a polarized chalcopyrite surface inhibits ferric reduction and that the presence of pyrite during chalcopyrite leaching can be beneficial. The electrochemical study was validated in leaching tests carried out in a stirred-tank reactor with fine chalcopyrite particles. Leaching was retarded at low temperatures due to the presence of an induction period. The duration of the induction period decreased with increasing temperature. The addition of pyrite significantly increased both the rate and the extent of chalcopyrite leaching. Complete conversion of chalcopyrite was obtained within 16 hours at 65C̕ at a pyrite: chalcopyrite mass ratio of 2:1. An electrochemical model that takes into consideration the galvanic interaction with pyrite and the "passivation" of chalcopyrite was proposed. The addition of microorganisms to the leaching system was investigated. Chalcopyrite was leached almost to completion (95%) within 30 days in the presence of thermophilic bacteria at low potentials and high temperatures. The bioleaching rate of chalcopyrite was further increased with the addition of pyrite. Finally, atmospheric leaching of chalcopyrite was carried out at 80C̕ under a range of conditions. Complete copper extraction was attained in 4 hours at a pyrite: chalcopyrite ratio of 4:1. The present study has shown that chalcopyrite passivation can be prevented at low solution potentials, high temperatures and in the presence of moderate amounts of pyrite.

Book Description :

The hydrometallurgical papers of Volume IV highlight optimization efforts in solvent extraction/electrowinning operations in North and South America. Biohydrometallurgy, for example, not only takes a key role in copper recovery in many leach operations but offers a new role in cost-effective environmental remediation. The discussions of several approaches to the treatment of copper sulfide concentrates emphasize the high level of interest in finding alternative means of recovering copper and precious metals and avoiding many of the costs and impurity issues associated with the conventional processing.
