The Advantages of Recycling Copper

The more copper recycled, the smaller the need for copper mining. Copper mining involves the usage of time, energy and fossil fuels. According to the Copper Development Association, the United States has no need to import copper. This is mostly due to copper recycling, which provides 95 percent of the copper for domestic usage.

How mining generates toxic waste

Open pit mining results in huge quantities of waste rock. First, to reach the underground ore deposit huge quantities of rock must be removed. This rock, called overburden, is dumped as waste. Secondly, the copper ore itself is very low Continue reading →
