Kalium Lakes Ltd (KLL) has signed a Letter of Intent (LoI) with EcoMag Ltd (EcoMag) to trial the recovery of Hydrated Magnesium Carbonate (HMC) as part of the large scale pilot pond works currently under construction at the Beyondie Sulphate Of Potash Project (BSOPP) in Western Australia.
EcoMag is the developer of a process for recovering magnesium-based materials from brines and bitterns, including HMC, which is used in the manufacture of chemically-toughened glass and fire retardants. It has a current market price of US$800 – US$1000 per tonne.
Ecomag has conducted analysis of a brine sample from the BSOPP, which indicate that the material is suitable for its process. The sample, provided from SOP tests completed by K-UTEC in Germany, had a magnesium content of almost 9.5%. Using the patented process, EcoMag achieved a magnesium recovery rate of more than 95% from the test sample, to produce 99.5% pure HMC.
The companies have entered into the LOI on an exclusive basis in relation to Western Australian based potash project developers. KLL and EcoMag will work together during and after the initial stages of the respective pilot projects.
KLL is currently finalising construction of its Large Scale Pilot Evaporation Ponds. EcoMag is currently in the process of building a transportable pilot plant to deploy to the BSOPP site and undertake several weeks of continuous operation in conjunction with KLL’s pilot evaporation pond trials.
Shaun Triner, EcoMag’s General Manager for Western Australia, said: “This agreement with Kalium Lakes provides us with an opportunity to demonstrate our process at scale.”
KLL’s Managing Director, Brett Hazelden, commented: “Working with EcoMag to produce a magnesium based product could generate additional revenue and increase profitability of the Beyondie Sulphate Of Potash Project. This in turn reduces risk and improves the potential return to our shareholders.”
