Predicting Acid Mine Drainage: Past, Present, Future

Total worldwide liability associated current and future remediation of acid mine drainage (AMD) is approximately 100,000 million US-$. Consequences of failing to predict AMD for individual operations and for the mining industry include unplanned spending on remedial measures and reputational damage. Despite these severe risks, predicting AMD properties of mine wastes is typically not an Get price

Acid Mine Drainage: Chemistry

Nov 10, 2004Acid Mine Drainage: Chemistry Acid mine drainage impacts stream and river ecosystems through acidity, ferric ion (Fe 3+) precipitation, oxygen depletion, and release of heavy metals associated with coal and metal mining, such as aluminum (Al 3+), zinc (Zn 2+), and manganese (Mn 2+).. When mineral deposits that contain sulfides are mined, they have the potential to produce acid mine drainage. Get price

Abandoned Mine Drainage

Abandoned mine drainage is water that is polluted from contact with mining activity, and normally associated with coal mining. It is a common form of water pollution in areas where mining took place in the past. There are several issues with abandoned mines that impact water quality: Get price

What can be done to prevent or clean up acid mine drainage

Some common methods include: Reclamation of contaminated land [2] by (1) adding lime or other alkaline materials to neutralize the acidity, and (2) Soil removal to relocate contaminated material to new sites where it can be monitored and treated [2]. Direct treatment of the contaminated water, Get price

Property Law: Altering How Surface Water Drains

The civil law rule: Paying for any harm you cause. In its simplest form, the civil law rule says that landowners are strictly liable for altering the natural drainage of surface water. The rule thus is the exact opposite of the common enemy rule. Landowners have no right to alter drainage, and they have the right not to be injured by others altering the drainage. Get price

Minimising environmental impacts from mining Fact sheet 4

Acid mine drainage (AMD) can be produced from mining activities. AMD typically has low pH and elevated concentrations of dissolved metals, primarily iron and aluminium. Mixed with surface water, AMD can result in unacceptable impact to the aquatic environment. Get price

Preventing water damage during construction projects

The best protection from water losses is through taking proactive measures to avoid water damage. Prevention is the best protection, and prevention requires a plan. Early in the process of starting a project, contractors should review the specific water damage exposures presented by each project as described in the following paragraphs. Get price

The Importance of Defining a Geochemical Baseline

that rehabilitation costs for acid drainage affected sites are likely to be in excess of A$100,000 per hectare, excluding the cost of treating water from mine workings. Currently, best practice environmental management of sulphidic mine wastes involves integration of acid drainage prevention, minimisation and control into the mining process. Get price

Acid Mine Drainage and Effects on Fish Health and Ecology

Acid Mine Drainage and Effects on The cost of mitigation of environmental damage from acid mine drainage is great. The U.S. Forest Service (USFS) estimates that between 20,000 to 50,000 mines are prevention, treatment and monitoring of potentially acid-generating materials and locations. A 1986 estimate for Canada suggests Get price
