Kalium Updates on SOP Production Timeline
Kalium Lakes Ltd., Balcatta, Western Australia, said on May 31 that it was able to validate its process design process during an April/May equipment testing program with production of approximately 400 mt of commercially saleable sulfate of potash (SOP) at its Beyondie SOP Project (BSOPP). The company said SOP production is building towards targeted first commercial sales in July 2022.
While Kalium achieved its first batch of SOP production last October (GM Oct. 8, 2021), difficulties intervened that required testing and a new production timeline (GM March 4, p. 31).
“We are very pleased that through recent equipment testing and the production of SOP we have been able to validate the overall process chemistry and plant design,” said Kalium Lakes’ CEO Len Jubber. “We are now focused on systematically addressing the remaining bottlenecks in the plant and progressively increasing production. Plant operations during 2022 will be variable, taking into account our need to conduct further mechanical debottlenecking activities and build KTMS inventory.
“Kalium Lakes is the first SOP producer in Australia, and we look forward to selling our first commercial production into the current extremely strong SOP price environment,” he added. “We believe the company has an exciting future, and we would like to thank all stakeholders, including shareholders, for their patience.”
The company said the SOP purification plant commissioning is proceeding as planned, with equipment testing well advanced and continuing into June/July 2022. Kalium said it has made significant progress in operational readiness with multiple appointments within the senior site team.
The company said the availability of sufficient KTMS (kainite-type mixed salts) to feed the plant is currently a production constraint; however, with improved pond operating procedures, it expects there will be sufficient KTMS by the end of August to commence the ramp up in production.
Until then, it plans to produce SOP at lower rates and undertake further optimization works during a plant shutdown in August, including the installation of a heat exchanger to allow improved operation during hot summer weather. Production will recommence in September, with progressive SOP output as the plant ramps up through to nameplate performance tests planned at the end of fourth-quarter 2022.
As previously outlined, Kalium expects the plant to be operating at an approximate 80,000 mt/y SOP production run rate by first-quarter 2023, with the targeted 120,000 mt/y run rate established by third-quarter 2023.
Kalium said discussions are advancing with debt providers, NAIF and KfW, and key offtake partner K+S Group on requisite funding initiatives in third-quarter 2022 and rescheduled SOP deliveries, respectively.
