@StGeorgesPlat @Steeltown12345 /
patent pending method of mineral recovery using a mixture of nitric and citric acid. leaching of #li from spodumene, slims, clay etc. without pressure, sonification or high temperatures.

@StGeorgesPlat #ecomining #greentech /
recently contracted a newly-built pilot plant facility owned and operated by CIMMS (cimms.ca) to further tweak the #li recovery process and the demonstration of commerical scalability.

@StGeorgesPlat #ecomining #greentech /
The objective of this R&D is not only to selectively recovering #Lithium but converting by-products to salable items such as fertilizer. Due to the selective nature of the leach mainly salt metals are leached out.

@StGeorgesPlat #ecomining #greentech /
The magnesium entering the pregnant leach solution might be converted to lithium magnesium alloys or high purity MgO. CIMMS has, in the past, done lithium and magnesium pilot plant work and imo is a good addition for this R&D.

@IconicICM /
has recently initiated a drilling program at #BonnieClaire which consists of 2 core holes and 3 RC holes. The RC drilling will provide additional samples for metallurgical testing by @StGeorgesPlat as well as expand the existing resource.

@IconicICM /
The core holes will be used in engineering studies for a Preliminary Economic Assessment. The depth of the holes is 300-400 ft and in the southern portion of the project in an area of anomalous surface lithium values and interpreted faults.

@IconicICM /
This is a unique & huge sediment-hosted deposit in Nevada. #BonnieClaire appears to be a new type of deposit that has lithium compounds like lithium carbonate and lithium salts deposited within the fine grain clay, silt, and sand pore space.

@IconicICM /
Even though the fine-grained portions of the sediment have particle sizes equivalent to that of clay it does not contain high percentages of typical clay minerals (less than 10% zeolitic clay). It's mainly quartz, calcite, feldspar & mica.

@IconicICM /
Elemental and crystalline analysis of the material indicated that the lithium was in a spodumene (LiAlSi2O6) crystal form and no chlorides were present. The spoduments found in the sediments represents approximately 3.2% by weight.

@StGeorgesPlat /
approch was to separate all particles below 5 microns mechanically & with air classification without loss of #lithium before selectively leaching the remaining material as this helps with chemicals consumption and tailings disposal.

@StGeorgesPlat /
A reduction of 55% of the initial feed material was achieved. Additional concentration with Nitric and Citric acid allowed for the elimination of up to 96% of the material without loss of #lithium.

@StGeorgesPlat /
The resulting 4% having 99.9% of the lithium still present in the solution and being equivalent to a 25-fold increase of #li concentration in the resulting solution. Required leach time is less than 20min at atmospheric pressure & ambient temperature.

@StGeorgesPlat / @IconicICM
Based on the projects current average grade of 963 ppm this would - in theory - result in a grade of 24,075 ppm lithium in the pregnant leach solution after the concentration steps took place.

@StGeorgesPlat /
The R&D efforts are now focused on further concentration and the reduction of acid losses in the residues due to the moisture content of the material, often up to 17%, that the clay sediment carries (this seems to be universal to all LiC projects.)

@StGeorgesPlat /
This phenomenon (up to 9% more moisture content compared to traditional lithium concentrates obtained from spodumene hosted in hard rock material) impacts the recuperation grade for the lithium via filtration press (up to 17% lithium loss).

@StGeorgesPlat /
The R&D team will conduct scaling tests with a proprietary adaptation of resin balls that will allow the recuperation of the lithium in the PLS without filtration to significantly reduce the loss due to the moisture content.

@StGeorgesPlat
Some impressions of the aforementioned pilot plant facility to do trials at a smaller and larger scale.

@StGeorgesPlat #lithum #patent
is looking at opportunities to apply its technologies to other advanced #mining projects, in particular, ones that currently produce #spodumene concentrate (but have not yet decided to build an expensive tech plant for refining).

total of 221 m (726 ft); both NQ (7.57 cm diameter) core holes had excellent recovery except in rare sandy beds. Dark green #claystone, indicative of #lithium bearing #sediments, were intersected from 2.4 m (8 ft) to total depth in both holes.
