Dr. Rodolfo García is Regular Associate Professor in the Department of Geology of Water Resources; Regular Associate Professor in the Chair of Economic Geology of Projects and Assistant Professor in the Chair of Environmental Geology and Geological Risks at the National University of Salta. Currently, he is an Interim Professor at the National University of La Plata, specializing in Lithium Geosciences. Geologist graduated in 1988 from the National University of Salta and Doctor in Geological Sciences in 1998. He was a fellow of the German Academic Exchange Agency (DAAD), based at the Universities of Tübingen and Darmstadt. He received a Gold Medal in his secondary studies. He was the best Graduate of the Faculty of Natural Sciences in 1988 and received the award for the best Graduate. Dr. García has extensive experience in the training of human resources, since to date he has directed more than 40 undergraduate professional theses and 5 postgraduate theses (masters and doctorates). He has participated in numerous national and international scientific meetings.
Lithium, in its pure form, is a soft, silver-white metal that oxidizes rapidly in the presence of air or water. It is the lightest metal, since its density is half that of water. It is found dispersed in certain rocks (pegmatite and sedimentary), but never free, given its great reactivity. The best known solid minerals containing this element are Spodumene and Lepidolite. The other way in which this metal is found is by forming salts in the groundwater stored in salt flat environments. The exploitation is carried out, unlike other minerals (metals or non-metals) in a very particular way since, in these cases, a fluid (brine) is exploited that contains dissolved, among others, lithium, potassium, etc. For this reason, to carry out the exploitation, a well is made that reaches the aquifer or aquifers that store a brine several times saltier than sea water (7 to 8 times more salty).
