Copper Fish I have been lucky enough during my few years as a human to travel through remote parts of this wild planet. North to South‚ on foot or by plane‚ I have seen firsthand how nations have either protected the land they possess or stomp it into the ground. My favorite trip of all time took place this last spring of 2013 on a road trip from California‚ through Canada and into Alaska. To say the least‚ it was a humbling trip to witness the vast expanse of untouched land I only dreamed of

is the difference between a’smart’ and a’smart’? Addison Hansen is studying the chemistry of a massive‚ alkaline (pH 11) tailings pond at a nearby coal mine. In the pond‚ there is an intense pH gradient between the surface and bottom. The surface tends to be significantly more acidic than the bottom‚ which changes the way that metals move through the solution. Many of the ponds are protected from rainfall or runoff from the surrounding area‚ but the pH gradient persists. Why do you need to be a member

valley. Whole hillsides and mountains were turned into tailings and debris that were dumped into the rivers and lakes of California. These tailings were called slickens‚ leading to the phrase of the day which said “slickens is too thick to drink and too thin plow” [SOURCE]. Mining operations employing these hydrolic methods destroyed the precious and untouched natural resources of California‚ flooded towns and inundated farmland with the tailings. While this particular method of mining was outlawed

Tar Creek is considered one of the biggest environmental disasters in the history of the United States. This disaster was created from lead and zinc mining in Northeast Oklahoma. Lead and zinc leftover in chat piles would seep into groundwater‚ ponds‚ and lakes contaminating almost all water in the area. The people from small towns in the area such as Cardin and Picher are at high risk for lead poisoning‚ which can have long term health effects. Tar Creek has been pinpointed as the reason for

land fill. This is after further minerals are extracted from the gangue. Waste products are also found in the froth flotation process. Here‚ the wet gangue is taken to a dam‚ usually lined with cement‚ called a tailings dam. The water is allowed to evaporate and the solid waste (tailings) is disposed of. It must however be disposed of safely as it may contain small amounts of toxic lead and zinc. Polluted water from the dam must be kept out of local water ways and prevented from entering the food

The remaining waste material‚ aka tailings‚ need to be disposed of. The water that drains or is pumped from mines or that flows from piles of waste rock or tailings often contains hazardous materials.

Environmental effects of copper Copper can be released into the environment by both natural sources and human actions. Examples of natural sources are wind-blown dust‚ decaying vegetation‚ forest fires and sea spray. Other examples are mining‚ metal production‚ wood production and phosphate fertilizer production. Because copper is released both naturally and through human activity it is very widespread in the environment. Copper is often found near mines‚ industrial settings‚ landfills and waste
