There is still time to join us for the upcoming EduMine webcast Advanced Tailings and Mine Waste Facility Design, Operation, and Closure.  Here is the link to the course.

Even if you have taken other courses before conferences, or the other EduMine webcast on Introduction to Tailings, or our previous Advanced Tailings courses, I know you will find interesting and exciting information, perspectives, practices, and case histories in this new course.

We have completely renovated the materials.  First we feature, on each of the three days of the webcast, a series of talks by Christian Kujawa, Robert Cooke, and Ian Hutchison on these topics:

  • Conventional tailings.
  • Thickened tailings.
  • Filter pressed tailings.

Christian and Robert are with Paterson and Cooke—they are leading consultants in making, transporting, and distributing tailings.  They have put together a great series of presentations on thickeners, cyclones, pipes conveyors, and the details of making and working with thickened, paste, and filtered tailings.  Their presentations will put you at the cutting edge of technology and practice in the production, transport, and distribution of all types of tailings.

Ian Hutchison is with SLR—he and his colleagues are experts in the design, construction, operation, and closure of tailings facilities.  They have assembled a suite of new case histories from North America, Australia, and South Africa.  Most are new to me—and I follow the topic pretty carefully.

I will come in from time to time to talk of theses new topics:

  • Risk assessment and decision-making for tailings management.
  • Dam safety inspections and evaluations.
  • Case histories on new project that I am working on–I am particularly proud that Nyrstar are permitting me to talk of closure planning for the Myra Falls mine here in BC.

In addition I will present summaries of the best new papers to be presented at the upcoming conference Paste 2014.  I have read all the papers and here I present a preview of those that impressed me most.  Time permitting, I will also talk about papers to be presented next week in Brazil at the conference on Mine Closure.

Lawrence Charlebois will spend an hour or so on that most difficult set of tailings topics, namely rheology, beaching, and Optimized Seasonal Deposition of polymer amended tailings.  For polymer amendment works.  I know that.  It just needs a bit of bold field application and the oil sands folk will be seen as heroes.

In short, this is a great opportunity to come up to speed with the newest & best in tailings.  Come join us and advance your knowledge & career by hearing from the most knowledgeable & experienced in the field.  I look forward to meeting & talking with you.  And it is a hell-of-a-lot cheaper than those expensive conferences where you fall asleep through dull presentations by amateurs.

I have no data to support the opinions I write of in this posting.  So please do your own research before deciding, panicking, or acting on anything said below. Today I was outside smoking in the damp rain when my smoking companion said that he had just surveyed the salaries of mining geoscientists (geologists and geotechnical engineers).  He noted that it appears that salaries for such folk are, on average, higher in Canada than in the USA.

In his book The Pencil: A History of Design and Circumstance, Henry Petroski tells at length of early graphite mining and its impact on the development of the pencil.  From what I recall, for many years there was but one deposit in England that produce graphite of the right quality to produce workable pencils.  As one reviewer of the book writes: (more…)

It is snowing in Vancouver.  Nothing sticking to the roads, but the trees are white and beautiful.  Nothing much to do outside or inside for that matter, so just  a few thoughts on mine waste disposal facility covers.

Slimes & Cement

The best cover is no cover.  If you can use the upper tailings or waste rock as the as the growth medium in which a stand of climax vegetation will flourish, you have the best cover. (more…)

The EPA’s decision about the prudence of developing the Pebble Mine or any other mine in the area of Bristol Bay is in–see this link. This blog (I/me) has been a consistent critic of the idea of developing the Pebble Mine.  In short, I cannot see how a mine could be developed in such an environment without unacceptable impact.

Virginia Beach has what is possibly the greatest collection of ugly public art I have yet come across.  Here are some pictures to prove my point. In addition to these pictures we saw the following scenes that I did not photography while wondering around. (more…)

At the address in the photo above is an amazing collection of public art.  On the outside walls of the Huntington Beach Civic Center are painted tiles of birds.  These tiles were saved when the old shopping mall across the way was torn down.  These tiles were part of this grand old shopping center–from a time when money could be spent on art not artifice.  But when the center was pulled down to make way for bigger shops that would attract the richer, younger crowd moving into the surrounding areas, luckily the tiles were saved and placed on the walls of the Civic Center.

The temperature in Huntington Beach today was 82 degrees–not sure what that is in degrees Celsius.  Regardless, we took a bike ride down to the beach and pier.  Here are some pictures of an hot Christmas in Southern California.

Bought the last of the Christmas presents today.  As always, I spent more on myself than on others. We bought the new Trek 24 inch bicycle yesterday for the grandson.  Today I bought a paint-the-glass kit for the granddaughter.  And the complete TV series of Two Fat women for my daughter.  I have not seen any of the episodes, but she swears the two fat ladies going around England on cooking trips is hilarious.  I bought myself a DVD of Leonard Cohen in concert. Will watch it after posting this piece. (more…)

I have moved on from countries and companies. I have left (and re-entered) countries. I have left companies and joined the principals in other companies. I have, in a word, moved around. At 67, I spend no time cogitating on these past decisions.  With so long a history of making decisions and moving on, I have so much to regret that I would go crazy thinking what would have been had I not made those many decisions.  It is futile to regret a past decision that may have been the wrong decision.
