قَدَّرَ بَاحِثُونَ تُونِسِيُّونَ أَنَّ مَحْلُولَ شَطِّ الْجَرِيدِ الْمِلْحِيَّ قَدْ يَحْتَوِي عَلَى نَحْوِ ١٤٢ أَلْفًا وَ٥٠٠ طُنٍّ مِنَ اللِّيْثْيُومِ. وَشَطُّ الْجَرِيدِ حَوْضٌ مِلْحِيٌّ وَاسِعٌ فِي جَنُوبِ غَرْبِ تُونُسَ. وَنُشِرَتِ الدِّرَاسَةُ فِي دَوْرِيَّةٍ عِلْمِيَّةٍ مُتَخَصِّصَةٍ.
يَدْخُلُ اللِّيْثْيُومُ فِي صِنَاعَةِ بَطَّارِيَّاتِ الْهَوَاتِفِ وَالسَّيَّارَاتِ الْكَهْرَبَائِيَّةِ، وَيُسْتَخْدَمُ أَيْضًا فِي تَخْزِينِ الْكَهْرَبَاءِ. جَمَعَ الْبَاحِثُونَ عَيِّنَاتٍ مِنْ مَوَاقِعَ مُخْتَلِفَةٍ، وَاسْتَخْدَمُوا الْقِيَاسَاتِ وَالْخَرَائِطَ لِمَعْرِفَةِ مَوَاضِعِ تَرَكُّزِ الْمَعْدِنِ. وَوَجَدُوا أَنَّ أَعْلَى تَرْكِيزٍ كَانَ فِي الْجُزْءِ الشَّمَالِيِّ الْغَرْبِيِّ مِنَ الْحَوْضِ.

Tunisian Study Estimates Potential Lithium Resource at Chott el-Jerid
Tunisian researchers estimated that the brine of Chott el-Jerid may contain about 142,500 tonnes of lithium. Chott el-Jerid is a large salt basin in southwestern Tunisia. The study was published in a specialist scientific journal.
Lithium is used to make batteries for phones and electric cars, and is also used to store electricity. The researchers collected samples from different locations and used measurements and maps to identify where the metal was concentrated. They found the highest concentration in the northwestern part of the basin.
But this figure does not mean that this quantity is ready to be extracted or sold. It is an estimate of a potential resource, and the economic feasibility of extraction is not yet confirmed. The estimate also depends on assumptions about the volume and depth of the brine.
Researchers need further studies to determine how much lithium can actually be separated. Concentrating the metal may require evaporating some water and processing large quantities of brine. Any future plan should therefore assess its effects on groundwater and the environment.
