| Abstract |
Surface waters in the Pine Creek Geosyncline (located in Australia's “Top End”, defined as the area of Australia north of 15 degrees S) are characterized by their low carbonate buffering capacity. These waters are buffered by silicate weathering and hence are slightly acidic, ranging in pH from 4.0 to 6.0. The Pine Creek Geosyncline contains most of the Top Ends' economic mineral deposits and characteristically shows no correlation between carbonate minerals and sulfidic orebodies hosting gold deposits (unlike uranium deposits). Thus many gold mines do not have ready access to carbonate minerals for buffering acid mine drainage (AMD). It is possible that locally available fast-weathering silicate minerals may be used to buffer AMD seeps. The buffering intensity of silicate minerals exceeds that of carbonate minerals, but their slow dissolution kinetics has ensured that these materials have received little attention in treating AMD. In addition, carbonate mineral dissolution is retarded when contacted with intense AMD solutions due to the formation of surface coatings of iron minerals. The lower pH range of silicate mineral dissolution may prevent the formation of such coatings. The Pine Creek Geosyncline consists of a complex geochemistry, and a number of fast-weathering silicate minerals have been noted in various areas. The difficulty in assessing such minerals for use in buffering AMD is the lack of kinetic data available under conditions prevalent AMD (i.e., low pH solutions saturated with aluminium and silica). This study sets out to evaluate the applicability of using such minerals to treat AMD surface seeps. |

| Abstract |
Die australische Goldlagerstätte am Mt. Leyshon wird im Tagebau abgebaut. Der Durchsatz der im CIP-Verfahren arbeitenden Goldaufbereitung beträgt 5,5 Mio t/a. Das Problem der Freisetzung saurer Grubenwässer wird langfristig durch selektive Bergeeinlagerungsstrategien und die Oberflächenversiegelung der Halden gelöst. Während der Abbauarbeiten sind jedoch auch unversiegelte Haldenflächen vorhanden, aus denen saure Grubenwässer austreten können. Diese Wässer werden durch ein System von Sammelgräben aufgefangen und einem Wasserauffangbecken zugeführt. Sie werden dort durch Kalkzugabe neutralisiert. Das so gereinigte Wasser gelangt über Pumpen in den Betriebswasserkreislauf zurück. Der Zufluß zum Auffangbecken ist mit regulierbaren Wehren versehen, die bei Hochwasser so gesteuert werden, daß ein Teil der sauren Grubenwässer direkt in die viel Wasser führenden Vorfluter abgestoßen werden kann. Zu dem Rückhaltesystem gehören auch Absetzbecken, die regelmäßig entschlämmt werden. Es ist ein kontinuierliches Monitoringsystem im Einsatz, das eine lückenlose Erfassung der Wassermengen und der Wasserzusammensetzung gestattet. |
