Chapter 2 The Environmental Effects of Strip Mining

Open Pit Mining Open pit mining is similar to area mining The technique is common in the western United States (and other parts of the world) where very thick — 50 to 100 foot — coal seams exist Open pit mines are usually large operations Production levels may exceed 10 million tons of coal per year The thick coal seams found at these large mines ensure that the amount of land

Copper production environmental impact

• Copper is recyclable without loss of quality • Copper is the most recycled metal after iron and aluminium • Around 40% of the demand for copper within Europe is supplied from recycled copper • Recycling a tonne of copper uses 20% of the energy that would be used to mine and extract the same copper
