This feels like something that could easily be tested small-scale.
To the lab!
Wait... I don't have a lab :(
Also, whales & dolphins etc won't like (even more) noise being pumped into their environment; although you could probably do the sound in a reasonably directional manner to keep it local. |

You'd almost need to do it in a confined space to ensure the geometry and resonance of the sound waves. |
|
| |
You'd create a current to channel vast amounts of salt water through enormous Cymatic filter chambers not harming a single critter riding the current. |
|
| |
If you are worried about species displacement then just make each current a loop returning fauna right where they got accidentally drawn into the loop. |

Honestly, we already owe the whales an enormous apology regarding hunting them to near extinction, taking all their food and cruising around with ships with noise generators so powerful they prefer to die than continue to share the water. I suspect that apology isn't imminently forthcoming, however. |

Using sound on an oceanic scale to mine metals for trinkets is much more on-brand for humans. |
|

The gold in seawater is dissolved, not suspended. |
|
| |
'Sonic displacement' sounds like some old-timey mental condition |
|
| |
Gold in salt water is both suspended and dissolved, this should collect both. |
|
| |
I'm pretty sure we could cancel any external sound if we didn't want to cause any more noise pollution for the sea critters. |
