LAKE SUPERIOR LITHIUM HYDROXIDE FACILITY OVERVIEW
Avalon Advanced Materials Inc. owns 100% of the property situated on the north shore of Lake Superior approximately 13 km northeast of Thunder Bay, at 965 Strathcona Avenue. It was formerly a pulp and paper facility last owned by Smurfit-Stone.
Figure 1: Location of Lake Superior Lithium Facility
METSO PROCESS DESIGN
The plant will utilize Metso’s proprietary technologies, which includes calcination, pressure leaching, conversion, purification through ion exchange (IX), and crystallization before the drying and packaging processes to ensure the production of high-quality lithium hydroxide monohydrate.
Metso’s technologies will enable the creation of a compact, energy-efficient lithium hydroxide production plant with minimal chemical usage, aiming to produce 30,000 tpa of battery-grade lithium hydroxide monohydrate (LHM).
A simplified Block Flow Diagram (BFD) of the process is shown below.
Figure 2: Simplified Block Flow Diagram of the Processing Facility to Produce LiOH
Notes: The production process includes the following stages: calcination of alpha spodumene, grinding, pulping of the ground beta spodumene, slurry preparation for pressure leaching, pressure leaching of β-spodumene calcine in an autoclave, solid/liquid separation of pressure leach slurry, conversion of autoclave residue, filtering and handling of leach residue, IX and solution polishing, crystallization of lithium hydroxide and product handling, and effluent treatment.
SITE LAYOUT PLAN
Avalon holds 154 acres of lake front property east of Thunder Bay as well as 220 acres of property covered by Lake Superior for a total of 374 acres. An aerial plan of the site layout has been developed and is shown in the figure below.
Figure 3: Plan View of Site Area
Infrastructure
The Project benefits from having significant existing infrastructure, enabling accelerated development of the project.
Roads
The property is accessed via Shipyard Road which intersects Strathcona Avenue. Strathcona Avenue is linked to the Trans-Canada Highway (Highway 11 / 17) by Spruce River Road just East of the property. Internal roads for the property will be developed to access all buildings for personnel movement and commercial deliveries.
Port
An existing deep-water port will provide access to the property via Lake Superior, enabling the products to reach customers in Ontario and beyond. Plans are in place to refurbish the existing port. An existing warehouse adjacent to the deep-water port will be utilized for offloading spodumene concentrate from the Great Lakes freighters. The warehouse will be refurbished and retrofitted with material handling equipment to receive the spodumene concentrate.
Figure 4: 3D Conceptual Design of Enhanced Deep-Water Port
Rail
A CN Rail line runs along the property dead ending just east of the property. A spur from the rail line currently enters from the northeast corner. The rail spur splits into multiple spurs and enters the existing warehouse adjacent to the deep-water port. Additional spurs will be added to allow for spodumene concentrate offload and analcime load out. The existing spurs entering the warehouse will require refurbishment.
Rail will be the primary method used for the delivery of spodumene concentrate when the lithium mines in the region come online in the years to come. Rail will also be utilized to transport reagents to site and byproducts from site.
Figure 5: Proposed Rail Offload
Spodumene Concentrate Storage
After being offloaded the spodumene concentrate will be conveyed from the rail and deep-water port facilities to a spodumene concentrate storage building. The facility will provide dry storage feed buffering for management of feed material and inventories, ensuring stable continuous operation of the process.
Fresh Water
Fresh water is required for the process, a freshwater intake is envisioned in Lake Superior.
Potable Water and Sewage
The property is serviced by Thunder Bay municipal sewage and potable water utilities.
