2. Mining Methods Copper

Open pit mining is a technique used to extract copper ore near the earth's surface. Open pit mining is the most widely used technique of mining copper today. It is accomplished by creating and using benches or terraces to gradually reach deeper under the earth's surface. Underground mining is used when the copper ore is not near the earth's

Copper Mining and Extraction Sulfide Ores

This KS3 education resource looks at copper mining, extraction and pyroprocessing of sulfide ores. Today, nearly one third of demand for copper is met through recycling, helping to conserve the earths resources. Copper is very well suited to being recycled because it can be remelted endlessly with no loss of properties. 90% of ore is

Methods of extraction Many metals are found in the Earth's crust as ores. An ore is usually a compound of the metal mixed with impurities. When the metal is dug up, a method must be used to separate the metal from the rest of the ore. This is called extracting the metal. The method of extraction depends on how reactive the metal is.
