Abstract |
In this paper experience obtained with THIOPAQ technology treating Acid Mine Drainage is described. THIOPAQ Technology involves biological sulfate reduction technology and the removal of heavy metals as metal sulfide precipitates. The technology was developed by the PAQUES company, who have realised over 350 high rate biological treatment plants world wide. 5 plants specially designed for sulfate reduction are successfully operated on a continuous base (1998 status). At Budelco, a zinc refinery in the Netherlands, an acid groundwater stream is effectively treated since 1992, removing metals and sulfate. At Kennecott Utah Copper (USA) a demo plant is in operation since 1995. An acid groundwater flow is treated to remove sulfate and metals, whereas the excess sulfide is used to selectively recover copper economically. Early 1998, a demonstration project was executed at the Wheal Jane mine in Cornwall, UK. In this demonstration project it has been proven that THIOPAQ technology can effectively be used to treat the Wheal Jane Acid Mine Drainage. Relative to lime dosing technology, very high removal efficiencies of all heavy metals (including cadmium and arsenic) can be obtained. |

Abstract |
Metalle und Sulfat können aus Grubenwässern in einem zweistufigen biologischen Prozeß entfernt werden. In der ersten Stufe wird das Sulfat durch Bakterien zu Schwefelwasserstoff reduziert. Dieser reagiert mit den gelösten Metallen zu unlöslichem Metallsulfid. Im zweiten Schritt wird überschüssiger Schwefelwasserstoff durch Bakterien zu elementarem Schwefel oxidiert. Eine nach diesem Verfahren arbeitende Anlage wurde 1992 durch die Budelco Zinc Refinery in den Niederlanden installiert. Diese verarbeitet täglich 5000 m(exp 3) Gundwasser. Zur Weiterentwicklung des Verfahrens für die Entfernung von Metallen und Sulfat aus Grundwasser und zur gezielten Kupfergewinnung aus Laugungswässern wurde 1995 in der Kupfergrube Bingham Canyon Utah, USA eine entsprechende Pilotanlage in Betrieb genommen. Anhand dieser Pilotanlage werden der Verfahrensablauf und erste Erfahrungen dargestellt sowie ein Überblick über das Untersuchungsprogramm gegeben. |
