LithiumBank has a portfolio of direct brine lithium projects, including Boardwalk and Park Place in west-central Alberta.
In September, the company announced that brine from the Boardwalk salar was processed through the adsorption circuit of the pilot plant and achieved lithium recovery of over 98%. The sorbent was then manually processed to desorb the lithium from the sorbent using a dilute sulphuric acid solution, producing the high-grade eluate.
The eluate quality reported is the result of a single cycle. Eluate grade and purity were largely in line with results predicted from previous test work at a lab scale announced in November 2023, LithiumBank said.
The company added that the recent desorption tests were consistent with its goals to minimize the flow volume and reagent costs. The average lithium upgrade from the feed was a factor of 44 times, while the low-cost sulphuric acid provided excellent rejection…
