Green Shift provides a metallurgical update of the Berlin deposit with high recoveries through membrane technology. Canadian Business Journal

TORONTO, November 9, 2022 (GLOBE NEWSWIRE) — Green Shift Commodities Co., Ltd. (TSXV: GCOM), (“green shift” or “CompanyResults of further testing work demonstrating that the membrane technology being tested at our Berlin deposit is highly efficient in separating uranium, battery commodities and rare earth elements found at our Berlin deposit. I am pleased to announce theBerlin”). Previous testing work showed that the membrane could significantly reduce the size of the treatment plant as well as simplify the recovery of phosphoric acid compared to the design modeled in the previous economic evaluation of the project completed in 2013. was shown. The results currently reported are from testing. It was the second phase of his three-phase testing program that was completed earlier this year.


  • This test work has successfully achieved over 95% recovery of uranium, nickel, vanadium and rare earth elements.
  • Phosphate recovery is relatively low and other membranes are tested to improve its recovery.
  • Improving the efficiency of the membranes separating rare earth elements could greatly increase the potential of the Berlin deposit.

Director and CEO Trumbull Fisher commented: The property contains commodities important to the global environmental movement for cleaner energy sources and energy storage. Additionally, we continue to look for other battery metal assets that will complement our core commodities in Berlin and support our vision of becoming a leading source of clean energy commodities. ”

membrane efficiency

Test work completed to date has demonstrated that membrane separation is consistent with the produced liquid, Precious Leachate (“PLS”), from synthesized liquids containing uranium, nickel, vanadium, rare earth elements, molybdenum, and zinc. It is shown to be a highly efficient process for concentrating . From the leaching of mineralized rocks from the Berlin deposit. The results show that metals are effectively separated from PLS. Phosphate recovery is not very good with the selected membranes, but we will explore options to improve this and aim for a target range of 80% to 90% recovery.

Product Recovery rate
Option A Option B
uranium 97.1 99.7
nickel 97.5 99.9
vanadium 97.0 99.9
phosphoric acid 79.3 63.6
rare earth elements 98.5 99.7
molybdenum 86.5 97.6
zinc 96.6 99.9
Flow reduction (%) 90.2 81.2

next step

  • Evaluate the potential costs/benefits of producing iron phosphate from Berlin in response to the rapid adoption of lithium iron phosphate (“LFP”) as a safe and reliable battery by the electric vehicle industry is a priority for us. Instead of simply producing phosphoric acid as originally thought, it will be evaluated whether phosphate from Berlin can be combined with iron to form iron phosphate for LFP batteries.
  • With rapid advances in sensor-based sorting technology, there is a need to test this with mineralized material in Berlin. This technology uses scanners to detect the physical and/or chemical properties of the mineral-bearing constituents of the crushed rock coming out of the mine, and jets of compressed air to remove the mineralized debris from the waste. remove. If this technology works with Berlin’s mineralized materials, it could significantly improve the efficiency of future processing plants and reduce operating costs.
  • Further work is planned to improve the recovery of phosphate from the previous 63%-70% to the target range of 80%-90%.

About Green Shift Commodities Ltd.

Green Shift Commodities Ltd. focuses on researching and developing the commodities needed to help achieve decarbonization and net zero goals.

The company is developing the Berlin deposit in Colombia. Apart from uranium, the Berlin deposit contains battery commodities such as nickel, phosphate and vanadium for clean nuclear energy. Phosphate is a key component of lithium-ion ferrophosphate (“LFP”) batteries used by a growing number of electric vehicle manufacturers. Nickel is a building block in various lithium-ion batteries, and vanadium is the element used in vanadium redox flow batteries. Neodymium, one of the rare earth elements found in the Berlin deposit, is a key component of powerful magnets used to increase the efficiency of electric motors and generators in wind turbines.
