Ann: Lake Resources Provided Kachi Project Update, page-302

Hi Propunter,

Looks like there’s multiple versions of what the pilot work in California was able to achieve.

“Lilac has processed the Kachi brine sample in a single step going from the average raw brine concentrations to a lithium eluate containing 3,000 mg/L Li, 400 mg/L Na, 250 mg/L Ca, 120 mg/L Mg, and 1 mg/L B, which can be readily processed through reverse osmosis and conventional purification technologies and fed into a conventional carbonate plant.”

“Lilac has achieved lithium recoveries from the Kachi brine sample into the lithium eluate of 80-90%. After downstream processing, this is estimated to provide an overall project-level lithium recovery of 70-80%.”

IMHO the demonstration plant work is comparable to the pilot work; however, I find it hard to say better.

The difference may only be in the capacity. Perhaps they used additional modules or larger modules in the demonstration than what was used in the pilot; however, I couldn’t find data to understand that.

Great research and I really like your superimposed diagram.

Thanks for sharing.
