Improved lithium processing demonstrated
The SiLeach® processing technology developed by Lithium Australia (ASX: LIT) is now one step closer to commercial reality, in that continuous pilot testing at ANSTO Minerals has demonstrated its ability to recover lithium solutions from mine waste.
Lithium Australia undertook an unusual challenge in using SiLeach® to process contaminated concentrate sourced from mine waste in the Kalgoorlie region of WA(ASX announcement 7 Sep 2018) and produce lithium-containing solutions. Remarkably, impurities in the concentrate had little, if any, effect on leach efficiency, with extractions as high as 97.5% being recorded.
Adrian Griffin, managing director of Lithium Australia NL (ASX:LIT), speaks to Proactive Investors about the two-stage SiLeach® pilot plant trial at ANSTO Minerals.
SiLeach® is a proprietary process for extracting lithium from mine waste materials to produce lithium chemicals. In a world first, Lithium Australia aims to convert mine waste to lithium-ion batteries.
Griffin describes Stage I results as ‘spectacular.’ Proactive Investors can reveal that Stage II testing began two days ago, producing lithium phosphate within 16 hours of starting up.
