RE:In other words you don't have a clue...speaking of not having a clue rat poison, your initial question shows your complete lack of knowledge on how the pilot plant operation works. You asked "how much brine has been recovered and how much lithium has been produced". Kind of backwards, it's the brine that they're producing and lithium that they're recovering.
Not going to do your DD for you. If you spent the time reading various tweets from Chris over the past couple of weeks, you would realize there is lots of brine being produced and you can do the math that greater than 94% is being recovered. As for rate of brine being processed, the flow rate through the DLE process is one of the variables that they will continue to tweak to optimize recovery of the lithium.
Go back and read the NR, closely this time, and you will see this statement:
"A full suite of results from the predefined testing currently underway will be available at the start of the longer operating period. At that point, E3 will provide the results against the KPIs outlined in June."
