Geology, Palaeontology & Archaeology / Is the Earth's core enriched for heavy dense elements, like gold?

In college, I spent time trying to figure out an economical way of extracting gold from sea water.
I considered using electrical current, centrifuge, boiling off the water, and even certain plants which take up metals through their root system, but none were worth pursuing due to the small size of gold particles, the volume of water needed to process, and the vegetation that would clog any filter.
One other gold resource that many geologists don't talk about is that found on sunken vessels. With advances in underwater cameras, robots, submersibles and salvaging, more "out of reach" ships are being salvaged for their gold and silver cargo.
