Recent developments have provided the opportunity to recover valuable materials from AMD treatment; this is a sustainable approach that allows to reduce waste while generating incomes that balance the cost of the treatment. This book provides insights to innovative and affordable routes for AMD valorisation that can certainly motivate the mining industry to effectively manage their wastes and minimize environmental impact while generating jobs opportunities.

Switching off the pumps of a mine is one of the last steps in the lifetime of a surface or underground mine. As the water in the open space raises, the water might become contaminated with different pollutants and eventually starts to flow in the open voids. This book addresses the processes related to mine abandonment from a hydrogeological perspective. After an introduction to the relevant hydrogeochemical processes the book gives detailed information about mine closure procedures. Based on in-situ measurements the hydrodynamic processes in a flooded mine are described and some of the mine closure flow models exemplified. As all investigations base on precise data, the book gives some key issues of monitoring and sampling, especially flow monitoring. Then the book shows some new methodologies for conducting tracer tests in flooded mines and gives some hints to passive mine water treatment. At the end 13 well investigated case studies of flooded underground mine and mine water tracer tests are described and interpreted from a hydrodynamic point of view.

Dieses Buch begleitet Sie auf einer Reise, die bei den Grundlagen von Grubenwasser beginnt und Sie weiter über die korrekte Probenahme für eine Planung bis hin zu den aktiven und passiven Reinigungssystemen führt. In den jeweiligen Kapiteln erfahren Sie die wichtigsten Techniken über die zu messenden Parameter (z.B. Vor-Ort-Parameter, Durchfluss), welche Methoden es gibt, um Ihr Grubenwasser aktiv zu reinigen (z.B. Dickschlammmethode, Umkehrosmose, Ionenaustausch) und welche, um eine passive Reinigung (z.B. konstruierte Feuchtgebiete, Vertikaldurchflussreaktor, Carbonatkanal) durchzuführen. Auch bekommen Sie einen Einblick in die Nutzung von Grubenwasser. Erwarten Sie kein Kochbuch – vielmehr ist es eine Zutaten- und Utensilienliste, die Ihnen dabei hilft, das richtige Rezept zu finden. Eine erweiterte Hilfe dazu erhalten Sie durch die nahezu 1000 Referenzen zu allen vorgestellten Techniken. Ich habe dieses Buch für Hydrogeologen, Ingenieure, Graduierte in höheren Semestern, Behördenvertreter, Bergleute, Geoökologen, Chemieingenieure – im weitesten Sinne also für Sie geschrieben.

This book accompanies you on a journey that starts with the basics of mine water treatment and takes you further through correct sampling for planning to active and passive systems. In the respective chapters you will learn the most important techniques about the parameters to be measured (e.g. on-site parameters, flow rate), which methods are available to actively treat your mine water (e.g. high density sludge method, reverse osmosis, ion exchange) and which ones to perform passive treatment (e.g. constructed wetlands, vertical flow reactor, limestone channel). You will also get an insight into the use of mine water. Don’t expect a cookbook – rather, it’s an ingredients and utensils list to help you find the right recipe. For extended help on this, check out the more than 1000 references on all the techniques presented. I wrote this book for hydrogeologists, engineers, graduate students, government officials, miners, geoecologists, chemical engineers – in the broadest sense: you.
