Abstract |
The paper discusses the different methods of mine water treatment used in the main coalfields of The Soviet Union. The technology used in treating the water in order to reduce suspended solids, salts, petrochemicals and bacterial contamination are fully described and the relative costs of each method are also given. The development of new methods of treatment and sludge disposal necessary to meet the requirements of recent legislation are also dealt with. |

Abstract |
In der Regenzeit 1991/1992 wurden überraschend im Bereich des australischen Goldbergwerks Pine Creek saure Grubenwässer festgestellt, die eine ernsthafte Umweltgefährdung und einen deutlichen Anstieg bei den Betriebskosten verursachten. Diese sauren Grubenwässer traten als Folge von Laugungserscheinungen in den Halden auf. Zur Verminderung der Reaktionsfähigkeit der sulfidischen Berge wurde beschlossen, die Halden mit mehreren Schichten inerten Materials geringer Permeabilität abzudecken. Diese Abdeckung wurde anschließend verdichtet und begrünt. Bei den späteren Abbauarbeiten wurde eine prophylaktische Minimierung der begünstigenden Reaktionsbedingungen vorgenommen. Es wurde eine Integration von Abbau und Sanierungsmaßnahmen realisiert, bei der offene Tagebauflächen mit Haldenbergen verfüllt wurden. Die haldengefüllten Tagebaurestlöcher wurden außerdem teilgeflutet, um den Sauerstoffzutritt zu minimieren. Aus den gewonnenen Erfahrungen wird die Schlußfolgerung gezogen, das AMD-Problem bereits in der Planungsphase zu berücksichtigen und umfassende Untersuchungen einzuleiten. Es sind nicht erst im Stadium der Sanierung, sondern bereits bei den Abbauaktivitäten geeignete Maßnahmen einzuleiten, um unangenehme Überraschungen durch saure Grubenwässer, die übrigens sehr teuer werden können, zu vermeiden. |

Abstract |
In Alberta, oil sands bitumen is utilized for synthetic crude oil (SCO) production by surface mining, bitumen extraction followed by primary (coking) and secondary (catalytic hydro-treating) upgrading processes. SCO is further refined in specially designed or slightly modified conventional refineries into transportation fuels. Oil sands tailings, composed of water, sands, silt, clay and residual bitumen, is produced as a byproduct of the bitumen extraction process. The tailings have poor consolidation and Water release characteristics. For twenty years, significant research has been performed to improve the consolidation and water release characteristics of the tailings. Several processes were developed for the management of oil sands tailings, resulting in different recovered water characteristics, consolidation rates and consolidated solid characteristics. These processes may affect the performance of the overall plant operations. Apex Engineering Inc. (AEI) has been developing a process for, thesame purpose. In this process oil sands tailings are treated with Ca(OH)(2) lime and CO2 and thickened using a suitable thickener. The combination of chemical treatment and the use of a thickener results in the release of process water in short retention times without accumulation of any ions in the recovered water. This makes it possible to recycle the recovered water, probably after a chemical treatment, as warm as possible, which improves the thermal efficiency of the extraction process. The AEI Process can be applied in many different fashions for the management of different fractions of the tailings effluent, depending on the overall plant operating priorities. |

Abstract |
Manganese is a common contaminant of mine water and other waste waters. Due to its high solubility over a wide pH range, it is notoriously difficult to remove from contaminated waters. Previous systems that effectively remove Mn from mine waters have involved oxidising the soluble Mn(II) species at an elevated pH using substrates such as limestone and dolomites. However it is currently unclear what effect the substrate type has upon abiotic Mn removal compared to biotic removal by in situ micro-organisms (biofilms). In order to investigate the relationship between substrate type, Mn precipitation and the biofilm community, net-alkaline Mn-contaminated mine water was treated in reactors containing one of the pure materials: dolomite, limestone, magnesite and quartzite. Mine water chemistry and Mn removal rates were monitored over a 3-month period in continuous-flow reactors. For all substrates except quartzite, Mn was removed from the mine water during this period, and Mn minerals precipitated in all cases. In addition, the plastic from which the reactor was made played a role in Mn removal. Manganese oxyhydroxides were formed in all the reactors; however, Mn carbonates (specifically kutnahorite) were only identified in the reactors containing quartzite and on the reactor plastic. Magnesium-rich calcites were identified in the dolomite and magnesite reactors, suggesting that the Mg from the substrate minerals may have inhibited Mn carbonate formation. Biofilm community development and composition on all the substrates was also monitored over the 3-month period using denaturing gradient gel electrophoresis (DGGE). The DGGE profiles in all reactors showed no change with time and no difference between substrate types, suggesting that any microbiological effects are independent of mineral substrate. The identification of Mn carbonates in these systems has important implications for the design of Mn treatment systems in that the provision of a carbonate-rich substrate may not be necessary for successful Mn precipitation.
