extraction
ik-STRAK-shun
/ɪkˈstrækʃən/
The process of removing something, especially a resource like oil or minerals, from the ground or a source.
While 'removal' is general, 'extraction' implies a systematic, often industrial effort to obtain something valuable that is embedded or hidden.
The story behind the word. From the Latin 'extrahere', which literally means 'to draw out'. Think of a tractor (from the same root 'trahere') pulling a heavy load; extraction is the act of pulling a resource out of its deep, earthly home.
