Here is the link to the new report Lower Athabasca Region Tailings Management Framework for the Mineable Athabasca Oil Sands.  In some fifty pages it sets out a new way of dealings with oil sands tailings.  Lots of detail yet not much detail. The document sets itself these goals: (more…)

Flexible Evaporation Solutions

Walked around the exhibit hall at the Denver SME convention.  Chatted to old friends and met new people–and learnt of new products. Suddenly my mind was cast back to my days as a kid on the East Geduld Mine in South Africa where we grew up.  The area was arid; there were no natural water bodies within two-hundred miles.  One of our favorite places was the mine’s evaporation ponds.  On our rickety bicycles we would break through the flimsy security gate and spend hours around the ponds.  They were magic: a wonderland of color and water.  Better than those fountains at the Bellagio in Las Vegas.

This evening I watched the Mariinsky version of Prokofiev’s Romeo & Juliet.  This is the only ballet I like.  Mostly because of the music.  And, I suspect, because once I could recite the entire Shakespeare play.  (I was Friar Lawrence in the  high school production.)  And now in the ballet I can hear the words of every emotion.

The translation above the pictures reads:

It doesn’t matter that it is Sweden’s most modern mine, built according to environmental laws, which the Government says is the world’s strongest. In addition, Northlands mine outside Pajala is a financial flop, it is now also an ecological disaster.
One million cubic metres of water with toxic heavy metals such as nickel, cadmium, lead, copper, and more flows straight out of the wrecked mine dam to Muonioälven and later the Torne River, which is classified as a national river.

At this link you will find four photos that appear to show the breach of the perimeter embankment or dike and spillage of tailings into the surrounding countryside.  Above is one of them.

The reports make little mention of the causes of failure.  Although the four pictures appear to show more than one breach.  A posting on Facebook dates the failure as 19 July 2014.

Please comment if you know more.

I have written extensively in this blog about the Alberta Directive 74. Generally I have been derogatory about the Directive. For example at this link I write the following: (more…)

While we in BC have been preoccupied by the Mt Polley situation, yet another tailings failure has occurred.  This time in Mexico.  That brings the number of failures this year to three:  Duke Energy, Mt Polley, and Cananea.  Just the right number if the probability of failure is one in five thousand.
