AMD Remediation Technologies (9 replies)
In addition to recommendation of the GARD Guide, You might scroll through the topics we have been discussing in this forum over the last couple of years. Quite a few have dealt with solution-treatment technologies and their merits/issues. Some number more have dealt with solid-waste management issues related to basic geochemistry (control of oxidation, for example). This also would have the additional advantage of introducing to you the people who hang out here."
Depending on which aspects of AMD remediation you are considering, there also are some recent publications by SME (in conjunction with others such as ADTI) addressing some specific issues, such a spit lakes. Two resources I keep close (though I am only a geochemist, not an engineer) are the Miner local Association of Canada's two short-course volume 22 (1994) edited by Blowes and Jambor, and volume 31 (2003) edited by Jambor, Blowes and Ritchie. Don't be put off by the dates, even of the 1q994 volume. They are full of great information and important data.
There are lots of information on Acid Mine Drainage, I think they have done several and much technical work on that topic, his related webpage has papers on introductory an specialized topics about AMD:

Other than that, they have done quite great contributions on those issues regarding both field and academic experience, you should also access to International Association of Hydrogeologists and International Mine Water Association journals and magazines regarding lots of information about Acid Mine Drainage.
I've read Mine Water: Hydrology, Pollution, Re-mediation by Younger, Banwart and Hedin from 2002. It's one of rather few existing AMD "Bibles" and a very good start i think.
Enjoy reading. Lots of information out there. One of the biggest issues we face with hard rock mining and rehabilitation.
The Mine Environment Neutral Drainage (MEND) website would provide you a lot of information pertaining to AMD and treatment technologies http://mend-nedem.org/category/treatment/)
MEND is a Canadian partner to the International Network for Acid Prevention (http://www.inap.com.au/)
Better start with GUIDE GARD. It would be helpful. Then, going for ICARD conference papers as well as some other relevant journals.
The only proven total remediation process available for AMD is the Bio-Aqua process, which we provide. It converts the acid into potable quality water and the contaminants into recyclable products that we sell and share the revenue with the mine. There are lots of partial processes available like lime dosing, RO etc, but these are typically methods of only separating the contaminants from the water. What is needed is a system that totally removes the water AND the contaminant from the site, does not import chemicals, and does not produce stored wastes.
I am new into the AMD topic. Does anyone know a good source to catch up with the most up to date AMD remediation technologies? (Proven and not-proven technologies) other than http://www.gardguide.com
