Book Description
This paper describes the bacterial leaching of a gold-bearing flotation concentrate consisting predominantly of pyrite in single-stage and multi-stage continuous reactor systems. The results of experiments under steady-state conditions are interpreted in terms of a logistic growth model, and the theory is shown to provide a useful basis for the design and scale-up of bacterial leach reactors. The results indicate that the critical dissolved oxygen concentration in the pulp may be as low as 0.1 mg/l.

Book Description
This book describes leading research in bioengineering for development of novel technologies for ferrous metal extraction. The author includes new developments in molecular biology, biochemistry, microbiology, cell metabolism, and engineering principles and applies them to the conventional iron ore industry - proposing innovative solutions to various industry challenges. The book focuses on applied approaches and describes emerging and established industrial processes, as well as the underlying theory of the process, and the biology of the microorganisms involved. Elaborates on bioprocessing technologies applicable for extraction of ferrous metals using cross-pollination of microbiology and extractive metallurgy; Presents a systematic overview of bioprocessing technologies encompassing laboratory research, pilot scale studies, and industrial process flowsheet design; Provides comprehensive coverage of the engineering principles behind bioprocesses of iron ores including material and energy balances, transport processes, reactions and reactor engineering.
