Abstract Acid mine drainage is recognized as a serious environmental issue at mine sites world wide. While sulphate and metal concentrations in acidic drainage can reach exceptionally high levels, these can also be elevated and of concern in neutral drainage from waste rock and tailings. “Neutral mine drainage” (NMD) has not yet received as widespread attention as acid mine drainage (AMD). The oxidation of sulphide minerals and the production of either acidic or neutral contaminated drainage is affected by many factors. This paper examines the specific factors that result in the production of “neutral mine drainage” from mine wastes. Several case studies are presented which involve predictive geochemical modelling to illustrate the possible time frame and magnitude of contaminated neutral drainage.

Title Assessment of the use of fast-weathering silicate minerals to buffer AMD in surface waters in tropical Australia Type Book Chapter
Year 1999 Publication Sudbury '99; Mining and the environment II; Conference proceedings Abbreviated Journal
Volume (up) Issue Pages
Keywords acid mine drainage Australasia Australia buffers carbonate ion geochemistry Northern Territory Australia Pine Creek Geosyncline pollution pyrite sulfides surface water tropical environment water quality 22, Environmental geology
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.

Title Control of acid mine drainage through water management at Mt. Leyshon Gold Mine. Die Beherrschung des Problems der sauren Grubenwässer im Goldbergwerk Mt. Leyshon durch Wasserfassungs- und Wasserregulierungsmaßnahmen Type Conference Article
Year 1995 Publication Second Australian Acid Mine Drainage Workshop, Charters Towers, AU, 28 31 March 1995 Abbreviated Journal

Keywords Bergbau Gold Australien Schwefelsäure Wasserkreislauf Wasserkanal Wasseranalyse Abwasserbehandlung Absetzbecken Umweltschutz Gewässerschutz Wasserverschmutzung Wasserwirtschaft Acid mine drainage Abwassererfassung
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.
