Zeotech Limited announced that it has successfully completed its first continuous closed-loop circuit, utilising kaolin feedstock to produce pure Linde Type A synthetic zeolite product. This marks a significant step in progressing the Company's dual-feed pilot program. Successful bench-scale continuous closed-loop circuit achieved utilising kaolin feedstock to produce pure Linde Type A synthetic zeolite product. Over 110 optimisation batch tests undertaken using Toondoon kaolin and Li process by-product samples, undertaken since May 2021. Over 30 continuous tests completed on individual process steps, involving leaching, filtration/decanting, and precipitation. Plant and equipment procurement underway, with construction and commissioning of pilot plant on track to commence early First Quarter 2022. During the H2 2021, the team at UQ completed in excess of 155 batch and continuous test runs. This work, together with the earlier start date on kaolin test-work, has led to successful development of the first continuous closed-loop circuit utilising Toondoon kaolin as feedstock to produce pure Linde Type A synthetic zeolite product. Since June 2021, UQ researchers have completed over 70 optimisation batch tests across a range leaching and precipitation configurations from two separate samples of Li process by- product. Continuous tank reactor precipitation work has been successfully completed and the team is currently undertaking continuous leaching runs. The inclusion of two separate Li process by-product samples to the pilot program, has increased the variables in validating ZEO's proprietary flowsheet process steps. Despite this, Zeotech and UQ expect to achieve a continuous closed-loop circuit in the near term. The completion of a successful continuous closed-loop circuit under the conditions of Zeotech's proprietary flowsheet, represents a major step in developing the configuration and design data required for scale-up to pilot line construction and commissioning, which is scheduled to commence First Quarter 2022. The focus for the remainder of 2021 is aimed at further optimisation of process steps targeted at achieving a continuous closed-loop circuit utilising Li process by-product. In addition, procurement of plant and equipment for the pilot line set-up has accelerated with key items scheduled for delivery early 2022.
