Antwort auf Beitrag Nr.: 61.098.763 von phobieeee am 24.07.19 21:04:30... St-Georges’ Research & Development Vice-President, Enrico Di Cesare commented: “(…) The development team is looking forward to progressing the technology further (…) knowing that the process works and can be independently executed is very encouraging. We are currently able to leach between 99.97% and 100% of the lithium in solution (...) the only improvement possible at this stage is to reduce processing time and the size of the feedstock with improved concentration. significantly improve what was developed in Phase I, covered by this report. (…) We are designing the pilot plant to keep a maximum of flexibility to improve the initial steps of the process. (…) We are looking forward to the big challenge that putting a 25t/w pilot plant in place represents for us. (…) The reception we have had from the local communities approached is very positive. People understand the need to produce lithium at low costs, and they embrace our commitment to green technology. The government support we have received until now is beyond what we would have normally expected. (…) We are now at the stage to increase and formalize our relationships with higher-learning and public R&D entities. We are hopeful that it will allow for even more innovation down the road (…)” ...

Antwort auf Beitrag Nr.: 61.098.784 von phobieeee am 24.07.19 21:07:18"The results indicated that the lithium was in a spodumene (LiAlSi2O6) crystal form, and no chlorides were present. This suggests that the lithium is not the residue of brines from a land-locked salt lake."

"Nitric acid was tried for selective leaching with positive results. At low temperature and with no pressure, 100% of the lithium was put into solution while avoiding the leaching of metals and most of the other elements. Other leached materials were carbonates (1/2 of the present iron was found under carbonate form) and salts (Mg, Ca including sodium and lithium). With the expected mined volume of over 7 million tons annually for 20,000 tons of lithium hydroxide produced, this type of leaching strategy could help keep capital costs down by, amongst other things, allowing for the design of a low-cost leach tank."

Antwort auf Beitrag Nr.: 61.098.820 von phobieeee am 24.07.19 21:12:13"St-Georges’ Process: Selective Leaching with Nitric Acid

Leaching with a passivating acid normally used to clean steel and passivate the welds of stainless steel was performed in the hope of selectively removing the magnesium (Mg) and all the salt metals like sodium (Na), calcium (Ca), lithium (Li) and magnesium (Mg).

The initial results with a 4-hour leach showed that all the salt metals and carbonate formations leached easily. This follows the logic of cleaning acid and leaves most of the other elements behind, such as silica (Si), alumina (Ai), potassium (K).

Multiple 1-hour leach tests confirmed the leaching of 100% of the lithium leaving behind most of the leachable elements from other acids such as potassium (K). The only loss of lithium that occurred during some of these tests was due to the water in the filter with the solids and represented less than 0.03% of the total lithium value. It also corresponds directly to the water retained with this type of fine material. Additional trials are being performed with reduced time of contact and temperature to optimize the lithium-bearing fines leaching.

The lithium in the super fines leached completely in each test performed with nitric acid. The trials to selectively optimize leaching the lithium with less calcium and magnesium are expected to be performed in the third quarter of 2019. It is expected that calcium can be reduced partially by filtering the coarser calcium formation as per SGS results and partially with less contact time with the acid. The same for magnesium. New samples will be treated once received.

Considering the results obtained, St-Georges is working on strategic partnerships for new organics mediums and resins that can work with nitric acid to selectively collect the lithium, as well as for electrolysis with nitric acid mediums. The Company also started to work on optimizing a new technology related to filter presses to reduce the facility size and environmental footprint, and to decrease chemicals usage and waste disposal. The new filter press design will be completed and available for viewing within two months. It is too early to know if this development initiative will result in intellectual property that can be patented."

Antwort auf Beitrag Nr.: 61.099.177 von phobieeee am 24.07.19 21:55:00Hört sich für meine laienhaften Ohren alles ganz gut/wirtschaftlich an.

Kalzium und Magnesium muss noch raus, aber da sind sie zuversichtlich dran....
Pottasche bleibt im Ausgangsmaterial zurück. Dadurch bleibt auch der "Abfall" weiterhin wertvoll und interessant für Weiterverarbeitung/(Verkauf ?)...

Vielleicht kann mal jemand "vom Fach" seine Meinung kund geben...

25t/w....das ist keine ganz kleine Anlage, oder ? Was kann so etwas kosten ?

Antwort auf Beitrag Nr.: 61.099.123 von Sailor68 am 24.07.19 21:51:00Laut meinem Verständnis dauert es aber noch Jahre bis die Anlage steht (stehen könnte).. Deswegen reagiert der Kurs auch nicht.
Weder hier noch bei SX.

Sie an ,sie an..
Den aktuellen Fragen bei Agoracom zu urteilen,
bin ich nicht der Einzige der sich verarscht vor kommt.

Alles sehr seltsam und gar nicht schön , wie die Altaktionären für dumm verkauft werden.
Aktueller Kurs sagt vieles .
