MDAG.com: Over Twelve Years of Providing Valuable Technical Information on Minesite-Drainage Chemistry and Environmental Geochemistry on the Internet
In 2010, we at MDAG
continue to focus on Internet case studies and
books, with less emphasis on publishing
papers at conferences and in journals. This allows us to:
- address issues of immediate concern to us;
- write case studies that are longer (e.g., MDAG Internet Case Studies
#25 and
#26) or shorter (e.g., MDAG Internet Case Study
#9 and
#30) than normally accepted by conferences and journals; and,
- fulfill our third corporate commitment "to
assist in the dissemination of non-confidential information and data through
publications and meetings to promote overall advancement of environmental
studies".
We are excited to present four new case studies on MDAG.com.
What do you find when monitoring drainage chemistry at minesites for decades, during operation and after closure?
Is the chemistry steady, or are there long-term trends?
Do aqueous concentrations show much dependence on pH or sulphate?
Here is what you find by looking at up to 31 years of monitoring data:
MDAG.com Internet Case Study 33. Thirty-One Years of Monitoring Minesite-Drainage Chemistry, During Operation and After Closure: The Bell Minesite, British Columbia, Canada.
MDAG.com Internet Case Study 34. Twenty-Nine Years of Monitoring Minesite-Drainage Chemistry, During Operation and After Closure: The Granisle Minesite, British Columbia, Canada.
MDAG.com Internet Case Study 35. Twenty-Three Years of Monitoring Minesite-Drainage Chemistry, During Operation and After Closure: The Equity Silver Minesite, British Columbia, Canada
Someone says, "microbial activity can greatly affect minesite-drainage chemistry, like accelerating sulphide oxidation by one million times!". Someone else says, "no, microbes hardly affect minesite-drainage chemistry at all!". Sound familiar? Here is what more than 80 references, back to the 1920's, have to say about that:
MDAG.com Internet Case Study 36. Microbial Effects on Minesite-Drainage Chemistry.
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 about 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.
