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.

More is said about mine closure than is done about mine closure.  Will they ever close Giant and Faro?  I doubt it.  Still if the topic interests you, here a few upcoming events. The InfoMine Mine Closure Conference in Belo Horizonte promises lots of information about mine closure in Brazil.  Not many of us can get that far south or want to go that far south. Last time there was an InfoMine conference in Belo, there were riots and protests and the delegates were confined to the hotel. (more…)

The general approach to undertaking a risk assessment is well described in International Standard IEC/ISO 31010, which also provides considerable information about risk assessment methods. It notes, however: “The standard does not provide specific criteria for identifying the need for risk assessment, nor does it specify the type of risk analysis method that is required for a particular application.” (more…)

Below is a report that hit my email inbox today.  I repeat in full, not because mines are the main culprit, but because mines are probably NOT the main culprit.  This report is a sobering reminder that dry-cleaners, car-battery recyclers, old military bases, and jails are also major contaminators.  Yet so little is written or done about them—it is not a very sexy topic–so much easier to excoriate mining. Not that Giant, Faro, and a few other old mines are going to be cheap to cleanup. (more…)

Today’s defeat of separationists and essentially racialist nationalists in Quebec is to be welcomed.  Even more so as today at the Cold Covers conference in Whistler two young engineers from Quebec were the bright stars of events.  They will be leaders in the future in all Canada in solving the issues of mine closure.

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.

The seminar on Cold Cover is upcoming in April in Whistler.  What a great opportunity for a few days of leisure and information in a beautiful place.  Just the thing for the privileged few in mining who can persuade their boss that they need & deserve the exposure to ideas and experts that would otherwise involve much web searching and downloading. I will be there — if this blog posting does not get me banned from attending.  For my challenge to the experts presenting is this: negate what I said so many years ago.  Do not obfuscate; do not formulate pusillanimous alternative to prove you are original; and tell us the truth.

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…)
