Abstract
A deep sea mining method includes providing a deep sea mining system for mining matter from a bottom of a body of water, the mining system including: a slurry line coupled with a pump system to transport the slurry from the bottom of the body of water; and a return line in fluid communication with the slurry line and distinguishable from the slurry riser, for transporting non valuable slurry part to the bottom of the body of water, the return line having a return line outlet proximate the bottom. The deep sea mining method further includes spreading the non valuable slurry part over the bottom of the body of water in a controlled manner.

Deep sea mining method comprising,
- providing a deep sea mining system for mining matter from a bottom of a body of water, the mining system comprising,
- a slurry line coupled with a pump system to transport said slurry from the bottom of the body of water,
- a return line in fluid communication with the slurry line and distinguishable from the slurry line, for transporting a non valuable slurry part to the bottom of the body of water,
- the return line having a return line outlet proximate said bottom,
- a spreading device coupled with the return line outlet,
- the spreading device comprising a boom member wherein the return line outlet is coupled with the spreading device through said boom member for moving the outlet relative to the bottom of the body of water, and
- the deep sea mining method further comprising spreading the non valuable slurry part over the bottom of the body of water in a controlled manner by moving the return line outlet over the bottom of the body of water.
