Rock Tech announces results from lithium hydroxide pilot plant in Germany – high quality, battery grade lithium hydroxide produced.
Rock Tech Lithium Inc. (the “Company” or “Rock Tech”) (TSX-V: RCK) (Frankfurt: RJIB) (OTCQX: RCKTF) announce completion of a pilot test program and prototype production of battery grade lithium hydroxide monohydrate greater than 99.5% purity, in compliance with end-user electric vehicle lithium-ion battery production specifications.
Rock Tech has been developing and optimizing a commercially proven process technology to produce battery grade lithium hydroxide monohydrate (BG-LHM) from various spodumene concentrates.
The process technology was developed to optimize conversion and purification of lithium from concentrates produced at several mining operations in Australia and North America.
The process technology was pilot tested at Anzaplan of Germany to demonstrate product quality using the process design developed for Rock Tech by Wave International of Australia. Several test programs are in progress at various equipment vendor test facilities to finalize the design and process equipment selection for commercial scale solution purification and crystallization circuits.
Through consultation with tier 1 end users, the Company planned and delivered a high-end product specification which exceeds the requirements of GB/T 26008-2020 D1, a Chinese technical standard commonly considered as the benchmark for BG-LHM.
The Company has targeted such a specification in order to attract tier 1 customers, and de-risk the future marketability of the Company’s product as customers continue to demand higher specification cathode materials over time.
Don Stevens, Rock Tech’s Chief Technology Officer.
We are pleased with the initial test results from our batchwise pilot program in Germany.
“The results demonstrate the functionality of our process flowsheet to produce high quality, battery grade lithium hydroxide and are key inputs into the design of our first planned commercial scale lithium hydroxide converter.”
The Company has received a sample of BG-LHM as a product from the Anzaplan pilot test program and has begun shipping samples to potential customers (end-users) for product quality testing as offtake discussions progress.
Dirk Harbecke, Rock Tech’s Chairman and Chief Executive Officer.
Discussions with potential LHM customers are intensifying.
“Understanding the performance of spodumene feedstock in our flowsheet and meeting potential customer product specifications are key milestones for us as we aim to build Europe’s first lithium hydroxide converter.”
