Metal extraction just like water distillation/purification/desalinization etc is a process whereby metal gets extracted (from the ore) (or water gets distilled/purified etc). Even if you're referring to one instance of such a process you'd still use this construction (without the apostrophe). In my opinion this structure is quite similar to "letter writing" where "letter" is certainly not a possessive.

Anonymouspeople at work are confusing me sayin that apostrophe can be omitted as jus an "s" implies the same.. that cannot be right? right!!Yes, I agree with you, the presence of an "s" at the end of words doesn't imply a possessive.
AnonymousAlso can anyone tell me how one can depict possession in case of acronyms because an apostrophe symbol with "s" as well as usage of simply just an "s" implies plurality in case of acronym, as in "late 1950's or 1950s"?1950 was a single year. This was the best selling song of 1950. It was 1950's best selling song. Here the ' means "of 1950."
