I know that nothing about Ivanhoe Mines / Kamoa Kakula was in the very latest CleanTeq report, but it all actually fits. If you notice that the Ivanhoe Quarterly states that improved copper capture was "benchtop" started 6 months ago, and if you look at the Annual report from CleanTeq put out just this last Sep 21, 2023, the below excerpt (page 25)
https://www.cleanteqwater.com/wp-content/uploads/2023/09/CNQ-FY23-Annual-Report.pdf
states that CleanTeq started work on Kamoa Kakula in that reporting period, which means that they started benchtop testing roughly 6 months ago....

Copper
Work on copper recovery from the Kamoa Kakula flotation tailings was initiated during this reporting period. A series of tests
have been conducted using chemical and physical methods to recover copper units from the flotation tailings.
The ongoing tests will determine the success and economic viability of this approach. If the results prove promising, the scope
of the project will be expanded to demonstrate the technology at a larger scale.
Both mechanical and chemical activation have shown improved outcomes, and the results are currently being evaluated for
potential full-scale applications. This progress represents a significant step towards maximising copper recovery and optimising
resource utilisation in the mining process.
