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 disposals.

They are suspended alternately with cathodes, which are thin sheets of pure copper. Most o the remaining impuritities in the anodes settle to the bottom of the tank and form a sludge. After electrolysis, the copper cathodes are usually melted in a furnace and cast into various shapes and sizes.
