About the Edition

Environmental management of acid generating tailings and waste rock has been a challenge facing the mining industry and government. With atmospheric oxygen as the crucial oxidant of sulphuric minerals, underwater disposal of tailings has been studied to reduce reaction rates. The water cover alternative of building a water cover on existing waste management sites was discussed.

The next section of this report provides an overview of the various methods used to dispose of mine tailings and the types of impoundments that are used. Section 3 describes the basic concepts used in the design of impoundments, including a number of site-specific variables of concern. Section 4 discusses tailingsFile Size: KB. The tailings water, after the filtering process of the mineral ores, contains a much higher concentration of heavy metals. For example, for the Navodari mine site, the tailings water contains cadmium up to 29 ppm, fluorine up to – ppm, sulphates up to – ppm, and phosphates up to ppm. The tailings water with a high Cited by: 6. in Boise County, Idaho. Topographical layout of the project site encompasses several hills, valleys, creeks, and roads. The elevation of th e mine pit is 2, m. The highest point on the mine site is Jackson Peak, which is located approximately m just south of the mine with an elevation of 2, m.   The mine tailings are also aluminosilicate rich, thereby they can be potential candidates for generating inorganic polymers according to the proceeding description. Furthermore, the cumulative storage of mine tailings in those three sites is practically over several million tonnes. Those mine tailings are currently underutilised all over the world!

For other tailings, the drainage waters would need to be managed adequately to prevent later impact on the flooding waters, once the mine is closed out. Tailing ponds present a considerable engineering and long-term management challenge (IAEA, b). Suitable dam materials and the construction of the retaining dams are important cost factors. UNITED NATIONS ECONOMIC COMMISSION FOR EUROPE. Safet ii aci ii iii iii. Foreword. Since the early s the United Nations Economic Commission for Europe (ECE) has committed itself to the prevention of, preparedness for and response to industrial accidents, especially those with transboundary effects in its region. Results indicate that flooding of preoxidized tailings can lead to the initial release of dissolved solids, acidity, and sulphate from the tailings to the overlying water cover. However, the overall impact of this release on the water cover can be minimal in the long term because of dilution from precipitation and fresh water inflows and.

Federal officials are not releasing details about the flooding of a tailings area at the Giant Mine site near Yellowknife. Federal officials are refusing to talk about the recent flooding of a.   On J , a mine-tailings reservoir belonging to the Knob Hill gold mine near Republic (Ferry County) breaks. When the foot section of the dam bursts, it releases a cyanide-laden flood. One family rushes from their home moments before the flood destroys it. The majority of currently available dam safety guidelines do not account well for the specifics of tailings dams. In the guidelines commonly used in Canada, tailings dams are addressed alongside water retention (conventional) dams. This results in an user-unfriendly, and potentially unsafe and/or inappropriate, treatment of safety aspects specific to tailings dams. A number of guidelines. Acid mine drainage from sulfur-bearing waste rock and tailings is one of the most serious environmental challenges facing the mining industry today (Campbell and Marshall ). It is caused when metal sulfides in the waste material react with water and oxygen to form sulfuric acid, which in turn dissolves residual metals such as nickel, copper.
