Mining Water Pollution Issues in BC

Types of Water Pollution from Mining There are four main types of mining impacts on water quality: 1. Acid Mine Drainage Acid Rock Drainage (ARD) is a natural process whereby sulphuric acid is produced when sul-phides in rocks are exposed to air and water. Acid Mine Drainage (AMD) is essentially the same process, greatly magnified. When large

WMANEnvironmental Impacts of Mining - WMAN

Acid mine drainage is the primary source of water pollution from mining. Mining unearths large amounts of ore that contains precious metals, such as gold and silver, as well as iron and other sulfides. When sulfides in the ore are exposed to water and air, sulfuric acid is created, which can seep from mines and waste rock piles into streams ...

10 Causes of Severe Water Pollution in Laos - Earth and Human

Mining requires heavy use of water in processing ore. When discovered metals or minerals are exposed to water, heavy metal contamination occurs. When the metals discharge from the stone, they run into the nearby water resources. It is how mining in Laos is causing water pollution. Wrapping Up. Water pollution is a real issue in Laos.

Mining and water pollution -- heavy metals, acid mine drainage

Here are the kinds of mining activities with the most water pollution Water pollution is caused by heavy metals or their leaching. It happens when certain metals such as cobalt, lead, copper, arsenic, zinc or cadmium, which can enter the food chain and significantly affect our health, establish contact with the nearby liquids.

Mining and Water Pollution — Safe Drinking Water Foundation

3. Processing Chemicals Pollution. This kind of pollution occurs when chemical agents (such as cyanide or sulphuric acid used by mining companies to separate the target mineral from the ore) spill, leak, or leach from the mine site into nearby water bodies. These chemicals can be highly toxic to humans and wildlife. 4.

Mining and Water Quality - USGS

Mining and Water Quality. Water running through mine tailings can become polluted. A U.S. Geological Survey (USGS) scientist and a volunteer sample metal-rich water from a seep draining a pile of mine tailings along Silver Creek, near Park City, Utah. Seeps such as this one can come from tailings piles that are remnants of past mining activities.

Mining and Water Pollution - SlideShare

Mining affects fresh water through heavy use of water in processing ore, and through water pollution from discharged mine effluent and seepage from tailings and waste rock impoundments. Increasingly, human activities such as mining threaten the water sources on which we all depend.

Pollution from Mining

An independent film "The Creek Runs Red" (on PBS) show the results of acid mine drainage on the small community of Picher, Oklahoma. More pictures and data are available on the Oklahoma USGS website. Mining provides essential raw materials for an industrialized society. However, it causes serious pollution of surface and groundwater.

Environmental Risks of Mining

There is no ore dust or direct ore exposure to the environment and a lower consumption of water is needed in the mining process (International Atomic Energy Agency [IAEA], 2005). However, the strong acids used to dissolve the ore body commonly dissolve metals in the host rock as well.
