Abstract |
A simulation model is developed of the efficiency and economics of an application of ecotechnology – using a created wetland to receive and treat coal mine drainage. The model examines the role of loading rates of iron on treatment efficiencies and the economic costs of wetland versus conventional treatment of mine drainage. It is calibrated with data from an Ohio wetland site and verified from multi-site data from Tennessee and Alabama. The model predicts that iron removal is closely tied to loading rates and that the cost of wetland treatment is less than that of conventional for iron loading rates of approximately 20-25 g Fe m “SUP -2” day “SUP -1” and removal efficiencies less than 85%. A wetland to achieve these conditions would cost approximately US$50 000 per year according to the model. When higher loading rates exist and higher efficiencies are needed, wetland systems are more costly than conventional treatment. -Authors |

Abstract |
The technical knowledge and practical experience accumulated by industry and others in abating acid mine drainage (AMD) is being proactively applied at every phase of the mine life cycle. This paper traces the mine life cycle from exploration to post closure monitoring and maintenance, and reviews AMD abatement measures that have become an integral component of exploration and mining activities. Attention is increasingly being given to evaluating AMD potential as part of exploration work, and studies related to project feasibility and design. Mining, mineral processing and waste management options are selected taking into consideration their suitability to inhibit AMD. These inhibition measures are typically committed to in closure plans submitted at the permitting stage. Mines are operated and decommissioned, often progressively, as planned and in accordance with environmental protection policies. Es wird über das Problem der Säurebildung aus sulfidischen Aufbereitungsbergen und taubem Gestein im Verlauf des Existenzzyklus eines Bergwerkes berichtet. In Kanada werden seit etwa 10 Jahren intensive Forschungen für Vorhersage, Kontrolle und Eindämmung von Saürebildungen im Bergbau betrieben. Schwerpunkt ist dabei die sulfidische Oxidation (2FeS2 + 7O2 = 2FeSO4 + 2H2SO4) unter Einwirkung verschiedener physikalischer, geochemischer und biologischer Faktoren. Diese Reaktion führt zu einem Komplex weiterer chemischer Reaktionen unter Bildung von zusätzlicher Säure und Lösung von Metallen. Daraus ergeben sich zwei Hauptmöglichkeiten diesen Prozeß zu steuern: 1. die Sulfidoxidation verhindern, 2. den Oxidationsprozeß verlangsamen. Mit dem heutigen Wissensstand ist es möglich, das Säurebildungspotential von Aufbereitungsbergen zu bestimmen, den Prozeß der Sulfidoxidation von Mineralen unter bestimmten physikalischen, geochemischen und biologischen Bedingungen zu modellieren und die Säurebildung von Aufbereitungsbergen und sulfidischen Gesteinen einzudämmen. Im einzelnen werden Maßnahmen zur Bewertung des Säurebildungspotentials und zur Kontrolle und Reduzierung dieses Prozesses während der Existenzstadien Exploration, Durchführbarkeitsstudie und Genehmigung, Gewinnung und Stillegung eines Bergwerkes erläutert. An Beispielen wird gezeigt, daß bei rechtzeitgem Erkennen des Säurebildungspotentials in der Phase der Exploration Verfahren und Maßnahmen bezüglich Aufbereitung, Umgang mit Aufbereitungsbergen ausgewählt werden können. |

Abstract |
Kontaminierte Grubenwässer des Uranbergbaus in Sachsen und Thüringen weisen eine regional schwankende chemische Zusammensetzung auf (Härte: 50 bis 1500 (Grad) dH, Sulfat: 2 bis 30 g/l, Eisen: 0,5 bis 4 g/l, Uranium: 1 bis 20 mg/l). Eine erfolgreich praktizierte Technologie der Abwasserreinigung ist dessen Verrieselung auf Kraftwerksaschen, die auf dichtem Untergrund bzw. dort, wo eine Grundwasserkontamination auszuschließen ist, aufgehaldet werden. Ziel ist es, den Nutzungsgrad der Asche zur Sicherung des Gewässerschutzes zu erhöhen. Eine geeignete Technologie ist dabei auch die Mischung von Asche und Kalk. Da die berieselte Asche bei der Einwirkung von natürlichen Niederschlägen ihre Kontamination teilweise wieder freisetzt, werden an die Verwahrung sowie Deponiebeschaffenheit von Aschehalden besondere Anforderungen gestellt. So muß beispielsweise die Verdunstung erhöht (Bewuchs, Vegetation) sowie die Dränage der infiltrierte Wässer verzögert werden. |

Abstract |
The performance of mine water treatment schemes, operated under the Coal Authority's national Minewater Treatment Programme, is summarised. Most schemes for which data are available perform successfully and remove over 90% iron. Mean area-adjusted iron removal rates for reedbed components of treatment schemes, range from 1.5 to 5.5 g Fe/m2, with percentage iron removal rates ranging from 68% to 99%. In the majority of cases, calculated area-adjusted removal rates are limited by influent iron loadings, and the empirical sizing criterion for aerobic wetlands, based on American removal rates of 10 g Fe/m2day, remains a valuable tool in the initial stages of treatment system design and estimation of land area requirements. Where a number of schemes have required modification after becoming operational, due consideration must always be given to the potential for dramatic increases in influent iron loadings, and to how the balance between performance efficiency and aesthetic appearance can best be achieved. Continual review and feedback on the performance of treatment systems, and the problems encountered during design implementation, will enhance the efficiency and effectiveness of the Minewater Treatment Programme within the UK. |

Abstract |
An historic underground copper mine in Wyoming is discharging neutral but copper-laden water into a pristine creek. The EPA-deferred site qualifies for reclamation by the Wyoming Abandoned Mine Land (AML) program. The cleanup goal is to restore the discharge so that the creek can eventually support a trout fishery. Hydrological and geochemical investigations underground have suggested two sources of mine water: one clean and the other containing copper. Results of bench- and pilot-scale tests support the viability of using low-cost passive treatment techniques to reduce copper concentrations in the near-freezing mine discharge. |
