Standard Lithium Provides Processing and Pilot Plant Update
Standard Lithium Ltd. (“Standard Lithium” or the
“Company”) (TSXV: SLL) (OTCQX: STLHF) (FRA: S5L), is pleased to
provide an update regarding the Company’s rapid progress in
developing and building a large-scale Pilot Plant for deployment at
the Arkansas project site. The Company and its Scientific
Advisory Team have been developing, testing and optimising
proprietary lithium extraction and crystallisation technologies on
Smackover brines for over a year, and are now at the stage where
the process flowsheet is sufficiently tested and proven to allow
procurement and fabrication to commence on the full-scale Pilot
Plant.
A lithium extraction Mini-Pilot Plant has been
operated continuously for long durations, and has demonstrated that
lithium can be selectively extracted from raw Smackover brine (i.e.
with no pre-treatment other than pH adjustment); can be converted
into a concentrated and substantially purified (compared to the
feed brine) lithium chloride solution; that the lithium-loaded
sorbent material can be continuously regenerated and recycled to
the extraction stage; and that overall lithium extraction
efficiencies of over 90% can be achieved. Completion of this
work has allowed design of the large-scale lithium extraction Pilot
Plant to be sufficiently completed, such that procurement of long
lead-time equipment has commenced. The procurement and
fabrication of the lithium extraction Pilot Plant is being
performed by Zeton Inc. at their design and fabrication facility in
Burlington, Ontario. Once fabrication of the modular Pilot
Plant is complete, it will be shipped to the Project site in
southern Arkansas for installation, commissioning and
operation. Initial site investigation and civil/mechanical
engineering design work have commenced at the Project site, and it
is expected that all site preparation and brine/utility
interconnections will be completed well in advance of deployment of
the Pilot Plant modules to the Project site.
In addition, the Company has been performing
testwork to selectively crystallise ‘battery-grade’ lithium
carbonate directly from the concentrated lithium chloride solutions
produced by the Company’s proprietary lithium extraction
technology. This testwork has been successful in making high
purity lithium carbonate material (>99.5% purity), and as
previously announced (see Standard Lithium news release 06th June
2018), the Company and its technology partners are currently
fabricating a Pilot scale crystallisation plant. This first
Pilot scale plant will be capable of running continuously, and will
serve as proof-of-concept that Standard Lithium’s proprietary
crystallisation technology can be used in place of existing OEM
crystallisation technologies. Should initial testing be
successful, then a larger Pilot/Demo scale crystalliser will be
constructed for deployment at the Project site.
Dr. Andy Robinson, President and COO of Standard
Lithium commented, “Our Scientific Advisory Team and technology
partners have been working tirelessly over the past 12 months to
develop modern, efficient and scaleable technology solutions
appropriate for deployment at our Project site in Arkansas.
We’re very excited that we’re now at the stage where procurement
and construction of the full-scale Pilot equipment has commenced,
and all project activities are aligned towards deploying the
full-scale modular Pilot plant in the first part of 2019.
Standard Lithium has some significant milestones ahead of us in the
next two quarters, and we look forward to sharing more details on
our projects and proprietary process technologies as we issue
technical reports over the coming months.”
