At this link are details of a new geosynthetic from CETCO. Basically it consists of two geotextiles between which is a reactive material selected to deal with contaminants commonly found in the mining and waste management industry. They describe it thus:

Reactive Core Mat (RCM) is a patented permeable composite mat consisting of reactive material(s) encapsulated in a non-woven core matrix bound between two geotextiles. The upper geotextile is a needle-punched, non-woven fabric that is heat-laminated to a matrix of nonwoven fibers needle-punched into a woven geotextile.

RCM is for in situ subaqueous treatment of contaminated sediments or post-dredge residual sediments and provides a reactive material that treats contaminants which are carried by advective or diffusive flow. A reactive cap allows for thinner cap thickness than traditional sand caps. The geotextiles provide additional benefits, such as stability and physical isolation. RCM can also be used for embankment seepage control and groundwater remediation.

Here are some reactive media that may be placed between the two geotextiles to deal with a specific contaminant:


Reactive Core Mat
Reactive Media Contaminants
Activated Carbon PAHs, PCBs
Apatite Heavy metals
Organoclay PAHs, PCBs, organo-Hg
Organoclay MRM PAHs, PCBs, Hg, As
* A variety of combined media can be made.


Demonstrates that there is no end to human ingenuity and invention. I am sure this will be a great new product that will find many uses in mining.

Andy Jung of CETCO alerted me to this new product.  I have asked him to prepare a full paper on its uses for the upcoming conference Geosynthetic Mining Solutions 2014 to be held in September in Vancouver.  By way of full disclosure, he gave me a bottle of champagne the other day as a way of saying thanks for my support of geosynthetics in mining.  With products like this, no bribery is needed to get me enthusiastic.  I am just delighted to see new ideas in practice.

PS. The following picture is of my daughter’s decorate graduation cap.  What is new and next?

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.

So better to attend the EduMine Webcast on Mine Closure.  You can do this at minimal expense from the comfort of your office or home study. I am the primary presenter.  I will survey some of the more interesting papers from the Belo conference to save you the trouble of visas, long hours in noisy planes, people in adjacent seats spilling into yours, taxis not to be trusted, and hotels that are refuges from rioters.  Not to mention dubious food that all are obligated to praise.

This is how the course is described:

This course is for those who are involved with or responsible for planning or undertaking current or future mine closure. The course covers all aspects of mine closure, from planning, financing, and implementation, to long-term surveillance and maintenance and walkway strategies. The course will introduce the basic ideas and challenges; advance through discussion of the latest financial, technical, and social approaches to mine closure; and end with a series of case histories of mine closure planning and implementation.

Topics to be covered in this course include:

  • Introduction and Basic Concepts of Mine Closure

  • Laws, Regulations and Standards for Mine Closure

  • Post-Closure Mine Use

  • Financing Mine Closure

  • Mine Closure Phases, Planning and Implementation

  • The Engineering of Closure

  • Social Issues of Mine Closure

  • Common Mistakes of Mine Closure

Today I put together many of the PowerPoint presentations.  Damn!  I am excited myself about all this.  So much new of interest.

I compiled a long presentation on the recent Cold Covers Seminar in Whistler—see the past four blog postings for my immediate opinions on this seminar.  I won’t repeat in the EduMine webcast, but will summarize the many fascinating case histories presented in the seminar.  And a few of the main ideas and issues raised and discussed.

Then I will survey the best papers to be presented in Belo.  Many are good and contain new and provocative ideas we all deserve to be exposed to.  You deserve to be exposed to them.  The best way is via my EduMine webcast.  Join us.

PS.  The picture above is me in a boat on the Amazon River in Brazil. And below a picture of what we saw.

In selecting topics to blog about, my first choice is something that struck me today as new and interesting.  Today the most fascinating new thing I learnt resulted from a visit by a young Irishman from Nuna Innovation Inc.  He told me about a geosynthetics that I had not hitherto been aware of.

Today I received a phone call from the editor of a site new to me on the topic of mining.  The site is Oil, Gas, & Mining.  He asked me to write an article for the site on the issues of geosynthetics in mining.  Thus I blog–by way of full disclosure I am influenced by the request.  But as is my standard philosophy, I write about a thing mining in anticipation that it will interest you.

The University of the Witwatersrand was  started as a mining school a hundred and more years ago.  Its greatest graduate was Nelson Mandela.  There have been many other graduates, including me.  None of us has changed & improved the human lot as much as Mandela did, but we have all tried to improve things to the best of our ability and education from Wits.

I have been much involved in the planning, marketing, and selling of the InfoMine conference Geosynthetic Mining Solutions 2014 to be held in Vancouver from the 8th to the 11th September 2014. (more…)

In addition to blogging, I consult to the mining industry.  And I work with Andy Robertson who also owns InfoMine to promote conferences — something InfoMine has decided to undertake in a big way. A few months ago, Andy asked me what topic I thought would make for a good conference.  A short reflection and I suggested geosynthetics in mining.   Way back in 1974 or thereabouts, I became familiar with geosynthetics when i used Bidim to make the base of a tailings facility in South Africa.  I became very familiar with geosynthetics about five years ago when Andy and I suggested geotextiles and geogrid placed on frozen tailings for the Suncor Pond 5 cover base.  In between, I have designed geogrid reinforced slopes, built reinforced walls, placed covers and liners, and read about geosynthetics.  (more…)

This morning I attended the opening of the conference on heap leaching taking place here in Vancouver.  Seem there are but 201 mines with heap leach pads.  There are 260 delegates–more than one delegate per mine.  Some 44% of the delegates are consultants; with 27 % from industry.  17 countries are represented in the attendees.  So a good mix.

Today was the first of three sessions of the EduMine webcast on heap leaching.  We continue tomorrow and Wednesday.  The webcast is well attended with people from as far away as the Congo and Brazil and as close as Burnaby, BC just east of Vancouver. (more…)
