Application of Nanotechnology in Mining Processes by Elvis Fosso-Kankeu,Martin Mkandawire,Bhekie B. Mamba Pdf
b”Application of Nanotechnology in Mining ProcessesNanotechnology 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.

Hybridized Technologies for the Treatment of Mining Effluents by Elvis Fosso-Kankeu,Bhekie B. Mamba Pdf
HYBRIDIZIED TECHNOLOGIES FOR THE TREATMENT OF MINING EFFLUENTS The main goal of this book is to review the principles, development, and performances of hybridized technologies that have been used for the treatment of mine effluents. Recent developments consist of the integration/hybridization of technologies to achieve the effective removal of pollutants from acid mine drainage (AMD) effluents in a stepwise manner such as to ensure that the cost of the process is minimized, and the resulting water is fit for purpose. This book presents eight specialized chapters that provide a state-of-the-art review of the different hybridized technologies that have been developed over the years for the treatment of mine effluent, including AMD. The successful implementation and challenges of these technologies are highlighted to give the reader a perspective on the management of such waste in the mining industry. In this innovative book, readers will be introduced to The limitations of passive and active treatment processes as stand-alone technologies while appraising the functioning and performances of these technologies when combined to address their challenges; The numerous approaches that have been considered over the years for effective combination of these technologies are explored taking into account their successful implementation at large scale as well as the long-term sustainability. Audience This book will be of interest to academic researchers from the fields of environment, chemistry, engineering, mineral processing, hydrometallurgy, geochemistry, and professionals including mining plant operators, environmental managers in the industries, water treatment plants managers and operators, water authorities, government regulatory bodies officers and environmentalists.
Environmental Degradation: Challenges and Strategies for Mitigation by Vijay P. Singh,Shalini Yadav,Krishna Kumar Yadav,Ram Narayan Yadava Pdf
This book discusses problems, challenges, and mitigation strategies in the wake of environmental degradation. It suggests proactive solutions to problems of environmental degradation for strategic planning as well as their effective delivery, and problems arising due to growth in population, industry, and land use change. The uniqueness of the book is its broader spectrum of coverage with related interconnections and interdependence of various aspects. Presenting a wide spectrum of viewpoints and approaches, the book covers topics, such as deforestation impacts (land use and land cover, soil erosion); impacts on climate change and human health; treatment of industrial, municipal, biological waste disposal and their impacts on soil, water, and air; recovery/remediation processes and technologies; impacts of pesticides and chemical fertilizers on soil degradation and groundwater; socio-economic environmental sustainability; and socio-economic health impacts. Particular focus is placed on strategic planning and methodological handling of environmental degradation and remediation through various processes and treatment technologies. This book will be useful to researchers, professionals, policy makers, and environmental engineers.

Reverse Osmosis Demineralization of Acid Mine Drainage by Donald G. Mason,Rex Chainbelt, inc,Mahendra K. Gupta Pdf
A two-phase study, involving both laboratory and field investigations, has demonstrated the feasibility of using reverse osmosis to provide potable water from acid mine drainage. The laboratory investigations involved the determination of methods for controlling iron fouling and the selection of a process flow sheet. During the field test, the process developed in Phase I was used to treat acid mine drainage from an underground abandoned anthracite coal mine. Treatment prior to reverse osmosis consisted of filtration (10 microns) followed by ultraviolet light disinfection. Brine from the RO unit was treated by neutralization, oxidation, and settling. Results obtained indicated that membrane fouling due to iron was satisfactorily controlled, but calcium sulfate fouling limited the recovery of product water to about 75%. Product water was of potable quality in all respects except for iron, manganese, and pH. Calcium sulfate precipitate on the RO membrane was successfully removed using a solution of ammoniated citric acid at pH 8.
Acid Mine Drainage by Geoffrey S. Simate,Sehliselo Ndlovu Pdf
Acid mine drainage (AMD) is essentially the flow of water polluted with metals and other substances from existing/old mining areas and is considered to be one of the sources of pollution.

Acid Mine Drainage: From Waste to Resources explores novel methods developed for the reuse and/or recovery of industrially useful materials from AMD including discussing generation, prediction, prevention, and remediation processes. It includes legislation and policy frameworks governing AMD and its environmental/health impacts. Provides a detailed overview of the mining operations and discusses the geochemical and hydrogeological context of acid mine drainage AMD formation, prediction and impact Presents a holistic approach to AMD generation, prediction, prevention, and remediation processes Presents exclusive material on reuse, recycling, and recovery of industrially useful materials from AMD Gives a detailed overview of the legislation and policy regulatory framework governing the management of AMD Analyses the effects of AMD on the environment and health This volume is aimed at researchers and professionals in metallurgical engineering, chemical engineering, environmental engineering, and mining engineering, including policy makers.
Neutradesulfating Treatment Process for Acid Mine Drainage by Catalytic, Inc Pdf
A process has been developed for treatment and removal of major pollutants in surface streams of Appalachia caused by acid mine drainage. The raw water is neutralized with sodium bicarbonate to precipitate iron and aluminum, followed by cation exchange to remove sulfate. Barium is eluted from the exchange resin and reacts with sulfate in the water to form a precipitate. Barium is recovered from the precipitate and is processed to recharge the exchange resin. The water is further treated to remove hydrogen sulfide by conversion to sulfur as a saleable byproduct. The process minimizes the cost of sludge and waste disposal while offering a product water meeting the highest interstate water quality standards. Treatment costs are given.
