Claim 6:
7. A method for mining the subsea floor comprising:
generating a first slurry by removing a surface layer of the subsea floor and mixing it with water;
flowing the first slurry into a separator;
flowing a portion of the first slurry through a fine particle screen to form a second slurry;
flowing the second slurry to be discharged into the ocean proximate to the subsea floor; and
collecting particles from the first slurry, that do not pass through the fine particle screen, at the bottom of the separator and allowing them to enter a stream of water from the surrounding environment to create a third slurry that is passed to a subsea pipe for pumping to the surface;
electrocoagulating the second slurry and discharging of the electrocoagulated slurry to the surrounding environment.
