METAL COLLECTION SYSTEM AND METHOD

摘要

PROBLEM TO BE SOLVED: To provide a metal collection system and method, by which a high metal collection efficiency can be maintained independently of the sea area where a metal collection material is installed.

SOLUTION: The metal collection system is constituted with: a mooring device 10 for mooring a metal collection material in a metal collection area W of seawater; and a temperature controller 20 for controlling the temperature of the seawater in the metal collection area to a target temperature. The target temperature is set within a temperature range of 25-35°C. The temperature controller 20 obtains the thermal energy required to control the temperature of the seawater to the target temperature by using one or both of waste heat and natural energy.
