To compare and analyze the sensitivity of each interval parameter on the interval nonprobabilistic reliability, make the deviation of parameters [c.sub.1] and [f.sub.1] of the tailing
dam change 0.002 toward both sides each time based on the previous deviation when calculating the interval nonprobabilistic reliability.
Petrov lake of glacial origin is situated in upper part of tailing
of Kumtor mining.
The site includes an operational molybdenum mine and milling facility, a tailing
facility and a tailing
pipeline running from the mill to the tailing
facility, EPA reports.
Says Ferguson, "You then build up an organic layer where you get bacteria, like algae, and in that way you reduce oxygen right at the top layer of your tailing
." To reduce the availability of sulfides to both water and air, other new techniques have been tried, such as autoclaving and encapsulating the rock in materials such as silica.
The Ministry of Natural Resources proposed to build a new tailing
and to produce a plan for conservation of the currently used tailing
to the Kumtor Operating Company to avoid possible emergency situations at the production facilities of the Kumtor mine.
When the content of the iron tailing
powder is 50%, the chloride diffusion coefficient of the concrete is little different from that of the single slag powder.
Delegates to the Colorado conference heard a presentation from Jeremy Boswell and colleagues at Thurber Engineering on some of the operational challenges experienced, and remedies found, where using thickened tailing
ITOGON -- The country's first and oldest mining company is rushing the rehabilitation of two tailings

In making this exciting announcement, Eldora Gold's Tailings
Processing division will begin to establish a new mill on its first prioritized tailings
disposal site in Kirkland Lake, Canada, having already conducted on-site sample testing and results evaluation.
Typical projects will include design/build solutions for dams, tailings
basin, waste piles, open pits, demolition, revegetation and other mining related infrastructures.

ONE OF YELLOWSTONE NATIONAL PARK'S most popular fly-fishing rivers is threatened by mine tailings
that, if set free by a heavy spring runoff, could poison and kill the ecosystem that supports its trout.
