Problems associated with the use of coal Hazards of mining and preparation. Coal is abundant and inexpensive. Assuming that current rates of usage and production do not change, estimates of reserves indicate that enough coal remains to last more than 200 years. There are, however, a variety of problems associated with the use of coal.
Toxic Waste. Modern industrial gold mining destroys landscapes and creates huge amounts of toxic waste. Due to the use of dirty practices such as open pit mining and cyanide heap leaching, mining companies generate about 20 tons of toxic waste for every 0.333-ounce gold ring. The waste, usually a gray liquid sludge, is laden with deadly cyanide ...

Mar 01, 2010· Acid Mine Drainage (AMD) is a widespread envi- ronmental problem associated with both working and abandoned mining operations resulted from the mi- crobial oxidation of pyrite in the presence of water and air. The product is a solution characterized by low pH and high concentrations of heavy metals and other toxic elements.
Many of the sources of stress to ecological systems are not specific to uranium mining, but may be associated with any mining activities or substantial ground-clearing development. The effects of mining can be divided into on-site ecological effects from the significant disruption of the land surface in the mined area and off-site effects.
