Acid Rock Drainage Potential in the Northwest Territories by Canada. Indian and Northern Affairs Canada Pdf

Inventory of quantitative information from active and abandoned mines in the Northwest Territories and assessment of the potential for acid rock drainage (ARD) within the mines' waste rock and tailings deposits. Of the 67 mines identified as relevant, only 27 could be evaluated because of lack of information. The mines were assessed for total stored volumes of tailings and waste rock; acid-generating potential of tailings and waste rock as determined by conventional acid base accounting tests; mineralogy of deposits, ore, and gangue; evidence of mineral oxidation in water chemistry data; type and abundance of sulphides in mine waste and tailings; length of time and conditions under which materials were exposed to weathering; and mitigative measures taken to limit or treat ARD arising from tailings and waste rock deposits. A summary of the geology for each individual mine is also included.

Mine Reclamation in Northwest Territories and Yukon by Anonim Pdf

Mine reclamation plan consists of ensuring that the physical structures that remain after mine closure do not impose a long-term hazard to public health and safety and the environment, which includes ensuring that the land and watercourses are returned to a safe and environmentally sound state and to an acceptable end use, considering the Best Available Technology Economically Achievable (BATEA).

Acid Mine Drainage, Rock Drainage, and Acid Sulfate Soils by James A. Jacobs,Jay H. Lehr,Stephen M. Testa Pdf

Provides the tools needed to analyze and solve acid drainage problems Featuring contributions from leading experts in science and engineering, this book explores the complex biogeochemistry of acid mine drainage, rock drainage, and acid sulfate soils. It describes how to predict, prevent, and remediate the environmental impact of acid drainage and the oxidation of sulfides, offering the latest sampling and analytical methods. Moreover, readers will discover new approaches for recovering valuable resources from acid mine drainage, including bioleaching. Acid Mine Drainage, Rock Drainage, and Acid Sulfate Soils reviews the most current findings in the field, offering new insights into the underlying causes as well as new tools to minimize the harm of acid drainage: Part I: Causes of Acid Mine Drainage, Rock Drainage and Sulfate Soils focuses on the biogeochemistry of acid drainage in different environments. Part II: Assessment of Acid Mine Drainage, Rock Drainage and Sulfate Soils covers stream characterization, aquatic and biological sampling, evaluation of aquatic resources, and some unusual aspects of sulfide oxidation. Part III: Prediction and Prevention of Acid Drainage discusses acid-base accounting, kinetic testing, block modeling, petrology, and mineralogy studies. It also explains relevant policy and regulations. Part IV: Remediation of Acid Drainage, Rock Drainage and Sulfate Soils examines both passive and active cleanup methods to remediate acid drainage. Case studies from a variety of geologic settings highlight various approaches to analyzing and solving acid drainage problems. Replete with helpful appendices and an extensive list of web resources, Acid Mine Drainage, Rock Drainage, and Acid Sulfate Soils is recommended for mining engineers and scientists, regulatory officials, environmental scientists, land developers, and students.

Treating Acid Mine Drainage from Abandoned Mines in Remote Areas by John J. Metesh Pdf

This paper describes the results and conclusions gained from the three demonstration projects. The paper concentrates on the characteristics of the processed material, equipment production, and the cost of the operation. Samples taken from windrows during the crushing operation were tested to determine hardness and gradations before and after crushing. The test results are included in the appendix. Cost varied from $6.38 to $18.83 per cubic yard, including roadbed preparation, crushing and blading. Rocks and boulders to‍?16-inch (406 millimeter) maximum size were crushed. The processed material has a maximum size of 2 to 3 inches (50 to 75 millimeters).‍?The product produced by the crusher offers a viable alternative for aggregate on a road surface, particularly as a road surface cushion material, where the quality and expense of standard crushed aggregate are not warranted.

Northern Aquatic Ecosystems and Mineral Development by D. Milburn Pdf

The Northern Water Resources Studies Program is one of two programs funded by the Department of Indian Affairs and Northern Development (DIAND) to deal with mining and the environment. Over the past two years, the Water Resources Division of DIAND has sponsored a series of workshops to review the current state of knowledge about the interactions between northern mineral development and aquatic ecosystems, to identify critical information or research gaps, and to devise a study program to fill those gaps. This report summarizes the findings of these workshops. It describes the environment of the Northwest Territories and Yukon; mineral development in the North and the potential impact from exploration, mine site development and operation, and closure and reclamation; and research needs and prospective studies on water resources, hydrological and physical processes, and biological and ecosystem processes.

The State of Canada's Environment by Anonim Pdf

Second national state-of-the-environment report, addressing the questions of what is happening in Canada's environment, why it is happening, why it is significant, and what Canadians are doing about it. The report is divided into five parts, dealing with perceptions of the environment and the dangers inherent in our tendency to look at the world in terms of human economic models; exploring the state of particular environmental components and the major sectors of human activity; describing six regional case studies; addressing six important environmental issues; and discussing the concept of sustainable development and its implications for Canada's future.
