Morphology
extraction = extract (semi-transparent) = ex + tract + ion
This is a standard noun formation from the verb 'extract', meaning the process of extracting.
Etymology
Extraction comes from the Latin parts ex- 'out' and tract 'pull', and it is the same idea behind extract, which means 'take out'. So in chemistry or industry an extraction is the process of 'pulling out' one substance from a mix, like oil or caffeine.
