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.

Mine Drainage and Related Problems by Brock C. Robinson Pdf
Acid mine drainage refers to the outflow of acidic water from (usually abandoned) metal mines or coal mines. However, other areas where the earth has been disturbed (eg: construction sites, subdivisions, transportation corridors, etc.) may also contribute acid rock drainage to the environment. This book discusses the effectiveness and sustainability of active and passive systems for the treatment of acid mine drainage; acid mine drainage in the Portuguese Iberian pyrite belt; the geochemistry of acid mine drainage and it's environmental pollution problem; the status of acid mine drainage and metal leaching in Ghana; the disposal and beneficial use of acid mine drainage sludge and a host of other related topics.

Part of Groundwater Set - Buy all six books and save over 30% on buying separately! Biffaward Winner 2002 The Clean Rivers Trust has fought off stiff competition to become the Research and Development - Technology Category winner at the Biffaward Awards 2002, with its project "Technology Analysis of Acid Mine Drainage Treatment Methods". Minewater Treatment - Technology, Application and Policy, was produced based on the findings of the research to aid in the selection, design and implementation of the most appropriate treatment techniques for particular minewater discharges. Much work has been carried out in recent decades concerning minewater treatment, both in the UK and worldwide. Many different bodies and organizations are involved in developing minewater treatment processes and schemes. Minewater Treatment addresses the need for a single source of state-of-the-art information that draws all the latest research material together. Key features of the book include: a full literature review of minewater treatment throughout the world an overview of relevant legislation and policy in a global context a review of currently available methods for treating minewater worldwide a site specific inventory of minewater treatment schemes within the UK, including compilation of available monitoring data and assessment of performance a review of emerging and innovative minewater treatment technologies and consideration of related academic research within the UK a comprehensive list of active and innovative minewater treatment technologies that are not currently compiled in a book or other review publication a detailed summary and recommendations section assessing the applicability, efficiency and cost-effectiveness of minewater treatment schemes Relevant scientific subject matter is presented in a concise, easily accessible manner to assist with the objective assessment of the progress made to date. Heavily illustrated with many colour photographs, the book allows best use to be made of the collective experience of minewater treatment practitioners throughout the UK, whilst at the same time placing the UK experience within a global context. An invaluable reference work for mining companies, consultants, planning officers, environmental research scientists, environmental agencies, water utilities and regulatory bodies, Minewater Treatment is a definitive source of information on minewater treatment technologies and will help facilitate the selection of the most appropriate technique required to tackle particular minewater discharge problems.

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.
