Vancouver, BC, Canada – TheNewswire - April 22, 2021 – Rock Tech Lithium Inc. (the"Company" or “Rock Tech”) (TSXV:RCK ) ; ( Frankfurt:RJIB); (OTC: RCKTF ) is pleased to updatethe market on progress of the Phase 1 pilot plant, metallurgicaltestwork and engineering development for its Georgia Lake andConverter projects.
-
- Phase 1 pilot plant at ALS fully operational.
- Lithium hydroxide samples from bench scale metallurgical testworkprogram expected in May.
- Metallurgical testwork program supports basic engineeringdevelopment for the Converter Project and the Phase 1 pilot plant.
Converter Metallurgical TestworkProgram
To support the basic engineeringdevelopment for the Converter Project and informthe Phase 1 pilot program (previously announced on February 16, 2021),a metallurgical testwork program has been ongoing since December 2020.Nagrom laboratories was appointed to complete a bench scale testworkprogram under management by Wave International.
The program was designed to prove the robustness of theflowsheet to produce Battery Grade Lithium Hydroxide from a range ofspodumene sources. Coarse DMS concentrate, low grade DMS concentrate,and combined DMS and flotation concentrate samples from various globalsources (including Georgia Lake, and commercially producedconcentrates) are part of the testwork program.
The testwork program for the conventional sulphationroute has progressed through the unit process of calcination, acidroast, water leach and impurity removal, causticisation andglauber’s salt crystallisation on the three different samples. CrudeLithium Hydroxide crystallization is currently in progress and a finalpurified Lithium Hydroxide sample is anticipated in May.
This work informed the Phase 1 pilot underway at ALSand will inform an upcoming stage 2 pilot, as well as providingengineering data for ongoing engineering development.
Figure 1 - Glauber’s Salt Precipitation Test
Nagrom, a privately owned Western Australian company,has been providing metallurgical services to the mining industry forover 30 years. Their Kelmscott facility (Perth, Western Australia) hasover 100 processing units and a staff of 120 skilled resources. Nagromis a recognized brand in the Lithium sector, with extensive spodumeneand downstream lithium testwork experience across major and emergingproducers.
Phase 1 –Lithium HydroxideMonohydrate Bulk Sample
Work is ongoing with ALSLaboratories, with purification and causticisation works complete. Thenext stages of the works are glauber’s salt crystallization,followed by crude Lithium Hydroxide crystallization. All testwork todate has performed as expected by the PFS conventional flowsheet, andper the bench scale testwork program. The final purified LithiumHydroxide sample from the Phase 1 pilot plant is anticipated to beproduced by June 2021.
The lithium hydroxide samples produced during themetallurgical testwork program and the Phase 1 pilot will be used tointensify offtake discussions with potential customers.
Georgia Lake Lithium Project
Heavy Liquid Separation (HLS) and Dense MediaSeparation (DMS) work has been completed on core samples from GeorgiaLake. Nagrom laboratories was appointed to complete this testworkprogram, under management by Wave International. The testwork programwas designed to test composites of different lithologicalclassifications across a range of processing parameters. In additionto contributing to the testwork program for further studies on theGeorgia Lake Lithium Project, it generated concentrate for theConverter metallurgical testwork program.
