Wrong again. The recovery rate is a function of how often the beads are changed. They previously optimised the project economics around a lower Lithium price and the optimum recovery rate to deliver the best project economics was 83%. A significantly higher Lithium price will allow improved project economics by changing the beads more often…..as the return for the extra Lithium recovered outweighs the additional cost associated with changing the beads earlier. The optimisation of exactly when they need to change out the beads for the best project returns is being calculated by the Engineers at this point in time. Pretty simple really.
