Can't comment on this, but I read during my chemistry years about a decade or two ago that people were considering recovery of gold, platinum and other valuable metals by electrolysis (your process) on seawater. The amounts present, overall, are astounding, but metals are so dilute that no one has found a commercial method.
Manganese, on the other hand, a valuable steel additive, precipitates naturally in the ocean, and was recovered quite extensively, though still experimentally, in the eastern Pacific about twenty years ago. Since that time, “black smokers”, or undersea volcanic vents, have been found to be sources of deposits such as this, but I’m not sure if they are the only source.
We always need to keep our eyes open for opportunity!
