    IMHO:

    Here’s a guesstimate of scale required to achieve DFS 25.5ktpa target.


    Assume that they mean a Lithium Chloride solution containing 1900 and 3800 mg/L of Lithium.

    Average say 2850 mg/L


    20,000L of LiCl solution between 1900 and 3800 mg/L Li in 600 hours.


    20000 x 2850 mg = 57000000mg Li in 600 hours


    57 kg Li in 600 hours.


    57 x 24 x 365 / 600 = 832 kg /year of Li (0.832 tpa)


    LCE = 5.323 x 0.832 = 4.429 tpa LCE


    25500/4.429 = 5757 demo plants of DLE equipment needed for 25.5 ktpa of LCE.


    ————————-

    Having made that guesstimate, I have difficulty interpreting the “The Demonstration Plant has now produced more than 15% of the total Demonstration Plant forecast output in the short period” with “Demonstration plant operating continuously at 90 percent of steady state, over 600 hours to date, toward the 1,000-hour requirement”


    15% in 600 hours for total of 1000 hours. 25% in 1000 hours?


    Perhaps then 15% output in 600 hours means 100% output is in 4000 hours.


    Hours per year is approx 8760.

    90% of 8760 = 7884 hours.

    4000/7884 =0.51


    Are they running only day shifts?
    If they are, but can run a full day then 5757/2 = 2878.5 demo plants DLE equipment needed for 25.5 ktpa LCE.


    This excludes losses in processing the LiCl solution to Lithium Carbonate.

    Interested in seeing your calculations.
