Quote from JaiSreeram:
...gold is so valuable that virtually none of it is ever destroyed by non-recoverable industrial consumption. Therefore, every ounce of gold that is mined annually is added to above ground total amounts.
As of 2005 there was ~240 tonnes of gold consumed annually via electroplating in electronics or for decorative use.
I doubt that even 10% of it is ever recovered.
