DEIONIZED WATER - SOLUBILITY OF LITHIUM ( 4 PEERS )
Was just reading up on a peer extraction report - pertaining to - the use of deionized water and the solubility of sodium and lithium.
The deionized water veered from the other undesirable salts and amazingly - solubilized
a good portion of the lithium and sodium.
This is the 4rd junior i've read up on pertaining to the studies on - deionized water leaching the lithium .
Now... cypress + noram + enertopia + iconic - performed tests on surface sooils.
3 of these juniors are in close proximity to that of, Albermarle.
The 3 juniors showed altered surface soils - hence - which allowed easier leaching.
culprit ?
most likely chloride....which altered the lithium to a salt crystal = making it easier to convert to a soluble solution in deionized water.
yet.. .what's so perplexing is...
the 4th junior iconic is no where near clayton valley - they;re a good 36 km away.
but.. if one looks at a map - several basins interconnect - and well - iconic is somewhat inline with - clayton's watershed path... which begs the question - could the chlorides wash 36 km away - or...how does one explain away thre success of leaching sediment lithium in a basin 36 km away from clayton ?
the lithium is either in - metal form - salt crystal form/
metal form needs acids....crystal salt form is soluble in water....
but not just any water... deionized or distileld water has no metal ions which makes the water pure and void of minerals...which also creates a vacuum or attraction inwhich the water molecules solubilize the salts and bond with the water.
which bring me to the subject....
Dajin should try deionized water on thier lithium soil samples at depth.
coring the basin and obtaining sediment samples at depth and then applying deionized water to the core sample to see if the lithium easaily leaches out.
lwhat might be occuring in the dajin basins is...
normal water with in, brines etc... might have the water molecules already loaded with salt ions - thus - there's no more room for a lithium or other salt to attach itself.
again - deionized water - has no minerals with in -
it has available seats inwhich to pick up the salts and bond.
would an operation of, impregnating the basin with deionized water allow the miner to liberate the lithium into a water bond - if water pump holes were positioned in key areas near horizons or saturation zones - allowing the lithiu mand the subsurface water ot carry the lithium into these zones - easier for miner ot pimp up - such as - exit zones or pinch points or entry zones ?
And again.... there's always - the testing of brines - looking for undissolved lithium.
most peer reports speak about total dissolved lithium - what about the undissolved ?
here's a peer report that describes how the deionized water veered from other undesirable salts and the outcome was quite impresive -
CYPRESS - 2017
Water Solubility of Lithium from Surface Rock Samples Comparison of Assays from Four Acid Digestion and Distilled Water Methods: Lithium Magnesium Calcium Potassium Sodium
The results from the table above show that the deionized water leach assay method would result in a water solution containing an average of 0.05% Li, 0.14% Mg, 0.11% Ca, 0.29% K, and 2.9% Na. These results are compared to other basin brine chemistries below in this study. The values are straight assay values for the elements as found in the deionized water solution used in the assay procedure.
The study looked at the solubility of each of the important elements in a fashion which compares the complete extraction of each element in the four acid method versus the partial extract using only deionized water. As the chart below clearly shows, two elements, lithium and sodium, show strong solubility into water versus a four acid solution while the remainder of the elements show remarkably low solubility in water versus a four acid solution. The difference is significant and the result is that a water solution is created which contains approximately 42% of the lithium and 81% of the sodium of the original rock but contains only trace amounts of the undesirable elements magnesium, calcium and potassium, all of which are less than 1%.
Wango -
Other junoors even had higher recoveries with deionzed water.
One was 56%.
if a junior presented say...
500 ppm in sediments and could liberate 42% of the lithium into a brine
that's 210 ppm - - -
600 ppm x .42% = 252 ppm
700 ppm x 42% = 294 ppm
800 ppm x .42% = 336 ppm
RATIO COMPARISON - CUBIC METER WATER vs CUBIC METER OF SEDIMENTS
the ratio of ppm on sediemnts would the ntranslate to -per tonne to per cubic liter
therefore - if there is 2.8 tonnes in a cubic meter and suppose 500 ppm was the average
it could translate into 500 ppm x 2.8 = 1400 ppm x .42% liberated = 588 ppm per cubic tonne of brine....this is not per liter but per tone of brine....
i have never yet read any junior calculating the liberating of lithium fro msediments into the water tables using the = 1 cubic tonne of sediments = 2.8 tonnes - into 1 cubic tonne of water - the 2.8 factor displacement presents an entirly new spin on - how much lithium might be displaced into the same voliume space of water - ultimately increasing the ppm in the water or brines... most juniors stick to - what's in the brine per liter -
now... how would this compare in cost to mine -
if compared to a dig and scoop operation that could achieve - 850 ppm average and 95 % extraction recovery ?
I would stil llean towards the brine operation al lbecause the ease inwhich to pump vs dig and scoop - entirely different operations and permitting.
the biggest unkown of all -
undissolved lithium in brines - vs - known dissolved lithium in brines.
this sort of comparison needs t obe seen ofr comparison.
why ?
all because if there's lithium in the sediments at say -500 - 600 - 700 - 800 ppm
its logical to think a portion of this lithium will also be in the brines or water....
going undetected.
3 tests must be performed -
brines at face value - what basin has disolved on its own
brines at face value - what basin has in - undissolved lithium on its own.
lab test - which adds acid - dissolve all salts to see - whats there - just incase there's
double or triple salt bonding - going undetected.
