Design of holding facilities for mine tailings
By Rudy McGillvray
May 11, 2015
I have developed an idea that has been germinating ever sine I've been listening to the " The Pebble Project " debates and statements about how it's going to destroy Bristol Bay fisheries. Well it will destroy those irreplaceable resources if the mine is put into operation without extensive prior planning as to the lays of the land and how to best use those lays to the benefit of all.
The primary thing that must need doing is to decide where the disposal pounds are located, and of what type and design. Are they 'wet pounds' with the allowance for leakage and whole dam breaches? Or are they dry storage with allowances for leakage and breaches?
In either case, they need to be drained not into the local waters, but back to where the overburden came from, the huge hole in the ground that is the result of this project. This may be a more expensive way to mine, sorry about that, but it's just about the only way.
(I feel) that this Project is going to be accomplished. Otherwise those minerals and gold and copper can sit there until my ideas take hold and it becomes less expensive to do it so that people's livelihoods are maintained, or the price of the materials being sought are of such value, that the method I have suggested becomes economically viable.
Yours, in a responsible mining Project,
