Today we completed a successful three-day EduMine webcast on mine closure.  Folk from Germany, Finland, Mauritania, South Africa, Australia, Guatemala, the USA, and Canada “attended.”  We are flattered and thankful to them and applaud their interest in a critical topic and facet of mining.  If you missed the webcast, contact EduMine and ask them to repeat it.

These past two days I have had to deal with that knotty subject, computer modeling for mines. I proposed a series of 2D runs in order to get a feel for how groundwater flows into an open pit and from the tailings facility. The younger generation cried in horror at my simplicity.  “We need 3D models to truly replicate the situations,” they protested. I protested: “We are not modeling things on the computer in order to replicate reality and create an electronic simulacrum of what is in nature.” (more…)

Next week in Brazil is the first InfoMine conference on Mine Closure.  About ninety folk will gather to discuss mine closure in Brazil and South America.  I have read the papers: not a lot of fascination to the rest of us.  Mostly about the theory and postulated future of mine closure laws & regulations in countries that currently have none. The middle of May, I present an EduMine webcast on Mine Closure.  In the  webcast I will review the best few papers from the Brazil conference.  I will also present current case histories of mine closure that I am working on.  And I will go through the theory and practice and issues of mine closure in general.  Come join me.

Here is a new document from the US EPA on treating mine-affected waters.  Free to download at this link and worth so doing. The document is titled:  Reference Guide to Treatment Technologies for Mining-Influenced Water (EPA 505-F-12-001). (more…)

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.

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…)

Treehuggers don’t like mining.  They fear: the loss of trees; cutting down of old-growth forests; turning the soil to extract rare earths for their computers and electric cars; and anything that changes the landscape.  Their websites call for replacement of cyanide by corn-starch, no use of mercury by artisanal miners, and windmills made of solid wood conveying electricity by means we know not of.
