Environmental Impacts of Mining

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 sulfid 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, rivers, and groundwater This seepage is called acid .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 bodi These chemicals can be highly toxic to humans and wildlife.

Mining Operations And Water Pollution

Mining operations use large amounts of fresh water to process recovered ore; the resulting mine effluent is typically a stew of hazardous acid-generating sulphides, toxic heavy metals, waste rock impoundments and water, and it is often deposited nearby in large free-draining piles where it can pollute land and water supplies for decades to come When this waste water drains into local streams .Mining by its nature consumes, diverts and can seriously pollute water resourc Negative impacts can vary from the sedimentation caused by poorly built roads during exploration through to the sediment, and disturbance of water during mine construction.
