Extracting Gold from Seawater Gold Refining Forum.com

Nov 03, 2014 · Knowing this fact, how would one go about in building a contraption to extract gold from this amount of seawater flow (5m3/s)? I was thinking of using some electrolysis method using carbon anodes to extract the gold. Can anybody suggest a better method? Even if you don''t have all the details, it would help me further in my research.
