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.

Spent today in a course on Covers in Cold Climates.  The course is part of the seminar to follow tomorrow and Wednesday on the same topics.  Arranged by InfoMine, it is being held in Whistler, which is a nice, but not spectacular place to have a conference—I prefer Banff or Vancouver.   For the Fairmont Chateau Whistler is a pale reflection of those other grand hotels with the Fairmont name: a bland and ugly exterior that replicates in cheap detail the features of the hotel in Vancouver that it tries to emulate.

Most engineers have no idea what the strength of a soil or tailings implies.  Let me write a little about the physicality of soil and tailings of a given strength. (more…)

I have some “I am sorries” to say.   I do this publically here as it gives me the opportunity to convey interesting information that may interest you. This is a story of the perils of blogging: no deep research before penning a posting.  And the dangers of just writing too much, too fast, for too many friends who lean on me to produce text for their websites.

The promise of results from risk assessments is as seductive as the picture above.  The results are as fuzzy and fantasy-based as the picture above.  But doing risk assessments is as much fun as it would be to be a participant in the scene above.  Let me explain. (more…)

The keynote address at today’s Tailings and Mine Waste 2013 conference was delivered by A.G. Kupper of BGC Engineering.  She made some amazing statements.  I wonder if she is fully aware of the implications of what she said. To me the statement with most import is that before an oil sands tailings facility can be de-licensed as a dam, it must be turned into a landform that will respond to long-term forces as does the natural surrounding landscape.  Until then the mine is on the hook.

Today I got onto site–past the security apparatus designed to deal with the normal, that is a contractor come to work and produce.  Being an idle consultant not wishing to pick up things, break or make things, and not wishing to drive big 350 trucks or ship hazardous waste, but merely to observe and opine, I finally got in via a simple, yet seldom used procedure.
