Salt Lake Potash Limited said it made substantial progress on the Lake Way sulphate of potash project in the second quarter of 2021 in Australia.
Construction of the Lake Way process plant was finalised with GR Engineering Services handing over the plant for Salt Lake Potash (SO4) to operate. Each of the 34 process units in the plant was individually commissioned with the SO4 operations team working towards achieving ‘Stage 4’ commissioning – bringing the plant into continuous operation and producing sulphate of potash (SOP).
Recent activities have primarily focused on the calibration of the flotation circuit to achieve expected recoveries, the company told investors. The company continues to work with the flotation circuit vendor and design engineer to bring performance up to modelled targets and expects the issue to be resolved this quarter.
Part IV environmental approval was received for the Lake Way project covering full-scale operations, including the expanded pond footprint and required brine abstraction infrastructure to enable the production of 245,000 tonnes a year of SOP.
Salt harvesting activities continued during the quarter and roughly 74,000 tonnes of plant feed salts have now been harvested and are ready as feedstock for the plant.
“The entire SO4 team has been working tirelessly through the harvest salt pond management system and plant commissioning challenges over the last few weeks. We are disappointed these challenges have pushed out our expected ramp-up profile; however, the project fundamentals remain attractive,” said Tony Swiericzuk, the chief executive officer.
