MDAG.com: Since 1997, Providing Valuable Technical Information on Minesite-Drainage Chemistry and Environmental Geochemistry through the Internet

 

************************

A major aspect in the prediction of minesite-drainage chemistry and water contamination is the upscaling of small-scale testwork to full-scale minesite components.  Unfortunately, this upscaling is usually done incorrectly, leading to an underestimation of full-scale and real-life severity.  One cause lies in the usage of scaling factors, through which small-scale kinetic rates are lowered and lowered yet again for full-scale predictions.  Read the details in MDAG Internet Case Study 38.

We have had the opportunity to collaborate recently with Mr. Getnet Betrie of the University of British Columbia Okanagan.  He has applied machine-learning and uncertainty-quantification techniques to minesite-drainage chemistry, discovering interesting results.  The published papers are listed here.

Interested in minesite-drainage chemistry, but not sure where to start? Looking for a basic introduction with dozens of colour photographs from minesites around the world?

MDAG Publishing has released an ebook by Dr. Kevin Morin, entitled Minesite Drainage Chemistry: An Introduction. This printable ebook in PDF format can be read on many ebook readers, laptops, and desktops. It costs CAD$5.00, can be downloaded immediately after online payment, and contains no digital-rights management or security limitations.

Click here, and then click the first link for the ebook.

We have also published many papers at conferences and journals, as well as Internet case studies and another book here at MDAG.com.

We steadfastly believe that the environmental effects of drainage chemistry can only be understood, predicted, and moderated by thoroughly understanding past competent work and by carefully studying existing operations and sites. Heed the old words of wisdom: "Those who ignore the past are doomed to repeat it". Is that why we hear that up to 90% of predictions of minesite-drainage chemistry are too low, leading to unexpected costs and environmental effects for mining companies?  This is why we heavily emphasize real case studies with abundant data, followed by theory and modelling in subordinate roles.
