acid rock drainage means any contaminated discharge emanating from a mining activity formed through a series of chemical and biological reactions, when geological strata is disturbed and exposed to oxygen and moisture as a result of mining activity.
acid rock drainage means acid waste discharge that results from the oxidation of metal sulfide in minerals associated with mined lands.
acid rock drainage or ‘acid mine drainage’ means any contaminated discharge emanating from a mining activity formed through a series of chemical and biological reactions, when geological strata is disturbed and exposed to oxygen and moisture.
More Definitions of acid rock drainage
acid rock drainage means any contaminated discharge emanating from a mining activity formed through a series of chemical and biological reactions, when geological strata are disturbed and exposed to oxygen and moisture.
acid rock drainage means water that has been impacted by the oxidation of mined sulfide
acid rock drainage. (ARD) means low pH (that is, acidic) surface or ground water that results from the oxidation of sulphide minerals or the dissolution of acid-generating minerals found in rocks and coal. This ARD, if it finds its way into nearby water bodies, can acidify these and create a toxic acidic environment. It can also dissolve other metals in the waste rock and allow these to enter into the environment.
acid rock drainage or “acid mine drainage” means any low pH waters, contaminated as a result of the mining activities.
acid rock drainage or “ARD” means acidified water resulting from the natural oxidation process in rock containing sulphides;
acid rock drainage means low pH surface or ground water that results from the oxidation of sulphide minerals or, elemental sulphur, or the dissolution of acid generating minerals found in rocks and coal.
acid rock drainage or “ARD” has the meaning set out in Section 13 40 00 of Appendix 6-2 [Technical Specifications];
