Green Shift Commodities (GCOM) provided membrane technology test results.

The test shows membrane technology being utilized and highly efficient in separating uranium, battery commodities and other rare earth elements.

The company’s Berlin Deposit shows that not only could membranes significantly reduce the size of the processing plant but could simplify the recovery of phosphoric acid in comparison to the design modelled in the previous economic assessment of the project completed in 2013.

The test work was successful in achieving uranium, nickel, vanadium and rare earth element recoveries of over 95 per cent. Phosphoric acid recovery is comparatively lower, and other membranes will be tested to improve its recovery. The greater efficiency of membranes in separating rare earth elements could significantly increase the potential of the Berlin Deposit.

The membrane efficiency test work shows that membrane separation is a highly efficient process of concentrating uranium, nickel, vanadium, rare earth elements, molybdenum and zinc from a liquid that was synthesized to match the pregnant leach solution (PLS). PLS is the liquid generated from leaching the mineralized rock from the Berlin Deposit. The results show that metals are effectively separated from the PLS. While phosphoric acid recovery is not as good with the selected membranes, further work will consider options to improve this – aiming for a target range of 80-90 per cent recovery.

Results of membrane test work showing the efficiency of metals and phosphate recovery from a pregnant liquor solution that simulated a PLS from the Berlin Deposit are shown in the image below.

In response to the rapid adoption of lithium ferro-phosphate (LFP) as safe, reliable batteries by the electric vehicle industry, the company is assessing the potential costs/benefits of producing ferro-phosphate from Berlin. The question is if phosphate from Berlin can be combined with iron to form ferro-phosphate for LFP batteries rather than simply producing phosphoric acid, as was first thought.
