u s processing and recycling technologies to utilize copper ore tailings

Energy Efficiency and Recycling: Start with Recycling

It's been estimated, in fact, that by recycling a single aluminum soda can, enough energy gets saved to power a 60-watt light bulb for four hours. Recycling also offers benefits, including reducing greenhouse gas emissions produced during the smelting and processing operations that companies use while making metal from ore.

Extraction of Resources

The result is that metal mining activities are expanding and more and more of the world's metal stocks are above ground in use rather than below ground as unused reserves. An example is the in-use stock of copper. Between 1932 and 1999, copper in use in the USA rose from 73 kilograms (161 lb) to 238 kilograms (525 lb) per person.
