Abstract:

In addition to containing the vast majority of Earth′s water resources,the oceans also hold huge amounts of mineral resources.At present,the resources obtained from seawater are relatively single and prone to waste,while also having adverse effects on marine ecology.The main resources,development methods,and future development directions of concentrated seawater,a byproduct of seawater desalination were summarized and analyzed.The resource development processes and current status of sodium,potassium,magnesium,lithium,uranium,and bromine in concentrated seawater was focused,the development trends of related processes and technologies were analyzed and summarized,and the existing seawater comprehensive utilization projects in China were introduced.With the implementation of the development concept of circular economy and green marine economy in China,the effective utilization and development of mineral resources in concentrated seawater would inevitably become new source of various resources.

Key words: desalination, concentrated seawater, resource extraction, circular economy
