Using solar energy to generate electricity and fresh water without damaging the discharge of industrial effluent into the sea has always been one of the main goals of the Millennium Sunflower Project.
Salt effluent from desalination contains very expensive elements such as lithium, which in this project is to be extracted from desalination brine using new technologies of lithium and other precious elements and sold in world markets.
The rest of the brine should be used after lithium extraction to produce ultra-lightweight building blocks in the construction industry.
Global demand for lithium metal, also known as 21st century metal, is widening due to the widespread use of lithium batteries in electric and mobile phones.
Most of the world’s lithium is extracted from the lithium triangle in mines in Peru, Bolivia and Argentina.
Lithium metal is very rare in onshore mines, but it is found in abundance in the seas, but in the form of separate ions with very low concentrations, which are very difficult and expensive to extract from seawater.
In Sunflower Millennium City using modern methods using nanoparticles as well as electrochemical cells containing ceramic membranes made of titanium lithium oxide (LLTO) salt effluent is used to produce lithium. It should be noted that the above methods are very new And is evolving.
