Title Engineering design aspects of passive in situ remediation of mining effluents Type Journal Article
Year 2003 Publication Land Contam. Reclam. Abbreviated Journal
Volume 11 Issue 2 Pages 113-126
Keywords Groundwater problems and environmental effects Pollution and waste management non radioactive waste management pyrite iron sulfide remediation mine drainage effluent
Abstract Passive treatment of contaminated effluents can offer a 'low cost' management opportunity to remediate drainages to the standards required by enforcement agencies. However, the initial cost of construction of passive treatment systems is significant and often in excess of that for active treatment systems. It is therefore important that the engineering design of the passive systems produces an effective and efficient scheme to enable the construction and maintenance costs to be minimised as far as possible. Possible parameters for the design of passive systems are suggested to seek to obtain uniformity in size and layout of treatment elements where this may be possible. Passive treatment systems include aeration systems, sedimentation ponds, aerobic and anaerobic wetlands, anoxic limestone drains and reducing alkalinity producing systems. Most active treatment systems also include passive elements in the treatment stream. The basic design considerations that should be considered to ensure the construction of efficient systems are discussed.

Title Acid mine drainage prevention and control options Type Journal Article
Year 2002 Publication CIM Bull. Abbreviated Journal
Volume 95 Issue 1060 Pages 96-102
Keywords acid mine drainage prevention tailings environment waste sulphides Groundwater problems and environmental effects Pollution and waste management non radioactive Surface water quality Waste Management and Pollution Policy tailings sulfide mining industry waste management
Abstract Acid mine drainage (AMD) is one of the most significant environmental challenges facing the mining industry worldwide. It occurs as a result of natural oxidation of sulphide minerals contained in mining wastes at operating and closed/decommissioned mine sites. AMD may adversely impact the surface water and groundwater quality and land use due to its typical low pH, high acidity and elevated concentrations of metals and sulphate content. Once it develops at a mine, its control can be difficult and expensive. If generation of AMD cannot be prevented, it must be collected and treated. Treatment of AMD usually costs more than control of AMD and may be required for many years after mining activities have ceased. Therefore, application of appropriate control methods to the site at the early stage of the mining would be beneficial. Although prevention of AMD is the most desirable option, a cost-effective prevention method is not yet available. The most effective method of control is to minimize penetration of air and water through the waste pile using a cover, either wet (water) or dry (soil), which is placed over the waste pile. Despite their high cost, these covers cannot always completely stop the oxidation process and generation of AMD. Application of more than one option might be required. Early diagnosis of the problem, identification of appropriate prevention/control measures and implementation of these methods to the site would reduce the potential risk of AMD generation. AMD prevention/control measures broadly include use of covers, control of the source, migration of AMD, and treatment. This paper provides an overview of AMD prevention and control options applicable for developing, operating and decommissioned mines.

Title Reactive barrier treatment of groundwater contaminated by acid mine drainage; sulphur accumulation and sulphide formation Type Book Chapter
Year 1998 Publication Groundwater Quality: Remediation and Protection Abbreviated Journal
Volume Issue Pages 451-457
Keywords acid mine drainage Canada chemical analysis contaminant plumes Eastern Canada ground water hydraulic conductivity hydrolysis Nickel Rim Mine Ontario pH pollution porosity pyrrhotite remediation sample preparation Sudbury Basin sulfides sulfur tailings water pollution 22, Environmental geology
Abstract A permeable reactive barrier was installed in August 1995 at the Nickel Rim Mine near Sudbury, Ontario, Canada, for the passive remediation of groundwater contaminated with acid mine drainage. The reactive component of the barrier consists of a mixture of municipal and leaf compost and wood chips: the organic material promotes bacterially-mediated sulphate reduction. Hydrogen sulphide, a product of sulphate reduction, may then complex with aqueous ferrous iron and precipitate as iron sulphide. This study presents the solid phase sulphur chemistry of the reactive wall after two years of operation, and discusses the formation and accumulation of iron sulphide minerals in the reactive material. The results from the solid-phase chemical analysis of core samples indicate that there is an accumulation of reduced inorganic sulphur in the reactive wall, with levels reaching 190 mu mol g (super -1) (dry weight) by July 1997.
