Summary:

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 bioprocessesof iron ores including material and energy balances, transport processes, reactions and reactor engineering.
