>Application of Nanotechnology in Mining Processes

Nanotechnology has revolutionized processes in many industries but its application in the mining industry has not been widely discussed. This unique book provides an overview of the successful implementation of nanotechnology in some of the key environmental and beneficiation mining processes.

This book explores extensively the potential of nanotechnology to revolutionize the mining industry which has been relying for a very long on processes with limited efficiencies. The nine specialized chapters focus on applying nanoflotation to improve mineral processing, effective extraction of metals from leachates or pregnant solutions using nanoscale supramolecular hosts, and development of nano-adsorbents or nano-based strategies for the remediation or valorization of AMD.

The application of nanotechnology in mining has so far received little attention from the industry and researchers and this groundbreaking book features critical issues so far under-reported in the literature:
_ Application of nanotechnology in mineral processing for the enhancement of froth flotation
_ Development of smart nanomaterials and application for the treatment of acid mine drainage
_ Recovery of values from pregnant solutions using nanoadsorbents
_ Valorization of AMD through formation of multipurpose nanoproducts.

Audience

Industrial interest will be from mining plant operators, environmental managers, water treatment plants managers, and operators. Researchers in nanotechnology, environmental science, mining, and metallurgy engineering will find the book valuable, as will government entities such as regulatory bodies officers and environmentalists.

Autorenporträt

Elvis Fosso-Kankeu has a doctorate degree from the University of Johannesburg in South Africa. He is currently a Full Professor in the School of Chemical and Mineral Engineering at the North-West University in South Africa. His research focuses on the prediction of pollutants dispersion from industrial areas, and on the development of effective and sustainable methods for the removal of inorganic and organic pollutants from polluted water. He has published more than 200 publications including journal articles, books (3 are with the Wiley-Scrivener imprint), book chapters, and conference proceedings papers. Martin Mkandawire is a professor of solid-state chemistry in the School of Science and Technology and former Industrial Research Chair for Mine Water Management at Cape Breton University, Nova Scotia, Canada. Before joining Cape Breton University in 2012, he was based at Technische Universitaet Dresden, Germany for 20 years. He serves on a few research foundations in Europe, Asia, South and North America, and Africa. He is the author of Ecowriting: Advice to ESL on Effective Scientific Writing in Environmental Science and Engineering. Bhekie Mamba is the Executive Dean of the College of Science, Engineering and Technology, University of South Africa since January 2017. He previously served as the director of the Nanotechnology and Water Sustainability (NanoWS) research unit at the University of South Africa. Prof. Mamba has published more than 250 journal papers, about 12 technical reports, and over 50 conference proceedings.
