ULM completed Locked Cycle Tests with Metso Outotec

In February 2023, ULM has successfully completed the Locked Cycle Tests (LCT) with Metso Outotec Finland. This testwork campaign was an extension of previous Open Cycle Tests by Metso Outotec – aiming to optimize the flowsheet for petalite concentrate for increasing recovery and mass pull (concentrate yield).

The final LCT results produced 3.4% Li2O in concentrate and 53.8 % of recovery, with a 21.4% mass pull. Some additional flotation tests are still in progress – to fine-tune the concentrate flotation process.

ULM also expects a completion of Dense Media Separation (DMS) tests currently processed by ADP Group by the end of March 2023– aiming to further improve concentrate recovery and yield results.
