With the same solution as (1), the relationship between [c.sup.r] and the interval nonprobabilistic reliabilities of the
tailing dam are obtained, as the solid red circle shown in Figure 5(a).
The
tailings ponds are located six miles west of the mine, which is surrounded by the Carson National Forest and is approximately two miles from the Latir Peak Wilderness Area.
AMD seeps out of fields of
tailings, piles of displaced surface matter ("overburden"), and piles of rock being slowly processed for gold removal.
Take economic and environmental factors into consideration, iron
tailings powder is an excellent admixture for concrete.
Itogon Mayor Victorio Palangdan said the
tailings dams were almost full and nearing their breaching levels.
Once extracted, these concentrates will contain the majority of minerals with recoverable metallic values presently residing in the
tailings, which coincidentally are the minerals responsible for the adverse environmental consequences of the original
tailings' disposal.
Wholly owned by Golder Associates Ltd., PasteTec offers consulting and EPCM services in the area of
tailings management, backfill production and placement and the handling and disposal of other waste materials.
The main reason for its increasing use is associated with the cost savings noted above but another major factor is the associated decrease in surface
tailings disposal.
When the mine and mill were operational,
tailings were pumped into a settling pond through which Soda Butte Creek flowed.
The second phase scheduled for 2002 includes pumping
tailings to the dam location at the northeastern section of the site and doing some wetland restoration.
