It costs between $1 and $40 a ton to build, operate, and close a mine tailings facility.  That is as specific as I was able to be when answering a question today in response to an enquiry from Australia.  There is a surprising paucity of data out there on the cost of tailings management.  We have details of salaries & wages.  We know the compensation of mining company executives.  We know how much it costs to engage and retain even the most expensive consultant.  But we have no data-base on tailings costs.

Categories are constructs of our imagination.  We define categories to aid our thinking, analysis, and decision-making.  It is easier to respond immediately if a stimulus fits a preconceived category, than to analyze afresh.  A rustle in the brush fits the definition of the category “Tiger in the woods; the tiger could kill us; therefore flee.”   Why analyze the situation to decide that the wind is merely blowing through the trees and making a nasty sound?

Paarl is the only South African brandy I can get in Vancouver.  It is rough—not like cognac—but rather the flavor of the veldt & bush, of scrub & dust, of a long-forgotten home & inequities long-rectified.  Thus inebriated, I blog. (more…)

The following just in from Venmyn Deloitte on reworking of old South African slimes dams or tailings facilities to use the more modern term.  All the old slimes dams around the area I grew up are gone.  The biggest loss is that big pile of yellow sand down which we would slide on corrugated cardboard boxes.  The pile was so full of uranium and gold that it was one of the first to go.  I hate to think what our radioactive exposure was as kids.  I can report no ill after-effects either from the radioactivity or from the mercury my father brought home for us to play with on the bedroom floor.  And we knew not what a seatbelt was in those heady days of vast exposure to danger.  (more…)

Paste 2013 and the Dragons of Tailings In Perpetuity

Posted in environmental, People, Tailings, tagged , , , , , on November 28, 2012 | 2 Comments »

The following is an “article” that I repeat as is from a recent ACG newsletter. Andy Robertson of InfoMine and Robertson GeoConsultants wrote this.  The “article” is at its simplest an announcement of an upcoming conference.  But at its most complex this is a scary story of potential dragons let loose on the world to scare the populace into non-mining.  Here is what he wrote: (more…)

Drive through the wilds of Arizona and New Mexico and see those magnificent red sandstone cliff, standing proud in spite of thousands of years of erosion.   It is one of my favorite sights.  It is spectacular to behold.  It tells me that landscapes can be the same for very long times. (more…)
