Pebble Mine: Politics vs Science & Engineering

Posted in consulting, Enviromental, North America, People, Reclamation, Tailings, tagged , , , , on October 2, 2012 | 9 Comments »

The debate–or is it a battle—over the Pebble Mine is becoming so intense that real wounds are being inflicted.  Reviewers are resigning and being fired.  The Pebble partnership is pressuring Jeremy Haile and his fellows at Knight Piesold into publishing tomes on past tailings failures.  Politicians demand full reports on secret deliberations.  And the EPA experts are, no doubt, still polishing the prose of their findings.  Leaving bloggers to blog.

Cover Technology in Mining: Wismut to Suncor’s Pond 5

Posted in Europe, North America, Oil sands, Reclamation, Tailings, tagged , , , , , on March 13, 2012 | Leave a Comment »

Clap! The sound a big volume of mining proceedings made when it landed on my desk this morning. Dropped from on high, this volume is the collection of technical papers from an International Symposium on closure of uranium mines at Wismut in Germany. If you haven’t heard of Wismut, then I suggest you get a quick bit of background information from a previous posting on ithinkmining . I have trawled the internet in search of an electronic copy of the preceedings but I can’t seem to come up with any. If anyone has a link, let me know and I’ll repost it. (more…)

Sage Grouse, Mine Rehabilitation, and Government Deficits

Posted in About the news, Enviromental, environmental, Reclamation, tagged , , , , on February 15, 2012 | Leave a Comment »

The proposed 2013 U.S. Federal budget includes $1M “to support research on rare earth elements.”   Compare this to the 2013 budget request for the Office of Surface Mining of $140.7M.  Compare this to the Bureau of Land Management request for $15M to “implement sage grouse conservation and restoration to help prevent the future listing of the species for protection under the Endangered Species Act.”  And an additional $25M “to be used for on-the-ground restoration programs and improvement of key sage grouse habitat.”  (more…)

Project Objectives for Management of Tailings, Waste Rock, and Heap Leach Pads

Posted in communication, Heap leach, mining, Reclamation, Tailings, Waste Rock, tagged , , , , on January 6, 2012 | 2 Comments »

Today I was criticized for failing to clearly set out the project objectives.  Damn me, I know what we are setting out to do.  “But the rest of us do not,” was the reply. And so I wrote out the project objectives in deliberate detail.  And that set me writing the rest of this posting.  It may be entertaining; I hope it is informative; as least it should give you some idea of the issues and events involved in mine waste disposal engineering.  (more…)

Frivilous Mining Conundrums: WalkAway Sustainable Solutions

Posted in acid mine drainage, British Columbia, decomissioning, Enviromental, Reclamation, tagged , , on December 21, 2011 | 1 Comment »

The sun is shining bright and the day is warm here is Huntington Beach, California, where I am spending time with kids and grandkids.  Somehow or other, the pressures of taking the kids to McDonald’s and other diverse hamburger places for lunch, riding the bike down to the beach, being nice at parties to old & new friends, and shopping for the festive season, have left no time for blogging.  Plus there were no obvious topics on mining that met the requisite level of interest and contentiousness.  (more…)

The Cost of Mining: Expansion & Environment

Posted in About the news, consulting, environmental, Reclamation, tagged , , , , , on October 13, 2011 | Leave a Comment »

Two news items today from the world of mining emphasize the cost of mining.  The first is that Jacobs has received contracts from the oil sands mines of Alberta worth more than $1.5 billion in the preceding quarter.  The second is that Hecla Mining has just settled with the EPA for $77 million to cleanup the Bunker Hill Superfund site in the Coeur d’Alene Basin in Idaho.
