Because ideas have to be original only with regard to their adaptation to the problem at hand, I am always extremely interested in how others have used them… – Thomas Edison

The quote above is not only quite reflective of the purpose of this book but also very meaningful to the topic of this book because Thomas Edison himself had per­sonally ventured in iron ore industry, which proved to be his greatest commercial failure. Discovering that beach sand contained relatively high grade of iron, he formed the Edison Ore-Milling Company in 1881 based on his patented methods of ore crushing and extracting the metal using a large electromagnet. He tried for many years to make that business a success. The demand was not there, and despite the new technological innovations that Edison brought to the industry, the company could not compete with the operations in the Midwest iron ore production. Eventually, the technology was sold to other mine owners. However, Edison was able to discover a market for the large quantity of waste sand produced from the ore-milling company and decided to set up his own cement company in 1899. The cement company later went on to supply the concrete for the construction of the Yankee Stadium in 1922.

I am not trying to introduce innovative ideas or concepts with guaranteed techni­cal or economic feasibility. Everything in this book can be found either directly or extrapolated from other literatures up to date. A mere rearrangement and compiling of all the information related to the topics is made in this book to give the readers an opportunity to understand some of the basic concepts and principles of iron ore bioprocessing, and to encourage readers to adapt and develop their own ideas to solve their problem at hand.

The information explosion has indeed created a situation where it’s now impos­sible for any one person to stay up to date with the changes in any topic area (unless that topic is perhaps so minute in its focus that only a few dozen are following it and contributing to the existing body of knowledge). The explosion of the shear amount of literature, and birth of interdisciplines and disciplines or subject areas in the past decades have been phenomenal. Biohydrometallurgy is one that is born of biotech­nology and mining engineering. With the maturing of bioprocessing as a discipline, it evolves from an interdisciplinary subject area of microbiology and hydrometal­lurgy to a discipline that covers the mining engineering and engineering science aspects of biotechnology, green chemistry, biomass, or renewable resource engi­neering. As such, books in the area are needed to cover the needs of educating the new generation of fine bioprocessing engineers, not just by converting well-versed mining engineers and engineering-savvy biologists to bioprocess engineers. With this book, I hope to fill this gap and bring the maturity of bioprocess engineering. Yet, some of the chapters in this book are more oriented toward industrial applica­tion aspects that are good references for process engineers and researchers who are looking for new process developments.

The key aspect that makes iron ore bioprocessing special is that iron ore biopro­cessing as an emerging field has potential to solve particular problems facing iron ore industry such as economic utilization of low-grade iron ore resources. Potential solutions stemmed from bioengineering functions and biological and chemical con­versions concerning the sustainable use of these resources are critical to revitalize the iron ore mining industry. Thus, the mechanism, rate, dynamic behavior, trans­formation performance, and manipulations of bioprocessing systems are the main topics of this book.
