Agree, it is farcical to call what SO4 has built a demonstration. Is the intention to review and revise the outcome of the demonstration?
It would be interesting to know if using the pit brine in the demonstration is a scientifically accurate approach.
Presumably the pit brine is simply pre-concentrated and part way through the sequence expected for native brine in concentrator ponds.
Nevertheless this demo isn't equivalent to what KLL has done or equivalent to what everyone , including APC, has done with native brine in small scale ponds.
They certainly haven't spent the time RWD has spent back mixing and tweaking the process.
