Acid & Metalliferous Drainage / Acid Rock Drainage

Since 1993, Earth Systems has been an industry leader in providing advanced geochemical services to the mining sector to manage or prevent the generation of acid to near neutral, metal and sulfate-rich drainage referred to as:

• Acid & Metalliferous Drainage (AMD)
• Acid Rock Drainage (ARD)
• Acid Mine Drainage (AMD)
• Metal Leaching / Acid rock Drainage (ML/ARD)
• Neutral Mine / Metalliferous Drainage (NMD)

Earth Systems’ team of geoscientists, environmental chemists and geochemical engineers provide integrated solutions to manage the impacts of acid drainage (AMD/ARD). From the characterisation of the acid generating potential of mine materials, through the specialist design of waste rock dumps and tailings storage facilities, to the assessment and treatment of a range of associated water quality issues, Earth Systems is focused on providing management solutions that make an difference today, while managing future risk.

Our experience encompasses a varied range of open pit and underground mining projects. These include precious metals (Au, Ag), base metals (Cu, Pb, Zn, Ni), tin, tungsten, molybdenum, uranium, iron-ore (hematite, magnetite), mineral sands (rutile, ilmenite, zircon, monazite), brown coal, black coal, graphite and diamonds, at mine sites across Australia, SE Asia, Africa, North and South America. Earth Systems’ specialist services have been routinely called upon at all stages of project development, including advanced exploration, feasibility, operations and closure or rehabilitation.
