SGS experts use environmental mineralogy to characterize acid generating minerals or phases to:
The characterization of the acid-generation potential of ores is a vital component in the management of ARD and the prevention of long-term environmental liabilities. SGS can perform a full mineralogical characterization of rocks, ore and tailings to determine their acid generating or acid neutralizing potential. From such characterizations, acid generating minerals (e.g. pyrite, marcasite, pyrrhotite) and acid neutralizing minerals (e.g. calcite, dolomite) are quantified.
The ratio of these acid generating or neutralizing minerals and their locked or liberation characteristics will determine if a sample will be a net acid generator, thus assisting with environmental planning, closure planning, and rehabilitation projects. This type of fundamental data can then be used to determine project costs.
SGS is a global technical leader in the field of acid rock drainage (ARD, also known as acid mine drainage) characterization and testing. We have years of experience globally, addressing the acid generating potential of mining projects and have earned the reputation as an organization that truly understands the testing required to define acid rock drainage scenarios.
