Innovations Introduction to Copper Mining Extraction

The barren rock, or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore. By far the greatest proportion of copper is extracted from the sulfides of copper, iron and sometimes other metals. Such ores originate from sulfur bearing volcanic magmas, which have separated into metal sulfides and siliceous melts.

Copper the Environment Copper Mining In A Cotton Field?

An in situ mine would obtain the desired material without disturbing the location. With conventional mining, large amounts of rock are moved to expose the ore, which then has to be mined so the copper can be extracted. The in situ process avoids almost all this work; ore is leached right where it is.

Environmental effects are usually based on damage caused by extracting the metal (eg mining for the ore, spoil heaps, toxic solutions leaching away after processing), depletion of the Earth's resources, unusable waste after the metal has been used. Again, good specific examples can be used to back up the general points. Hope this helps.
