Ann: Pre-Construction Locked-Cycle Testwork Completed, page-20

Hi Names

The core purpose of locked-cycle testwork is to obtain a projection of continuous cycle (real-world commercial operation) flowsheet performance through conducting cycled lab batch tests. Certain parameters are varied under controlled conditions and the effects on overall flowsheet performance can be quantified. Effectively very detailed optimisation work geared toward commercial processing at Kwinana - final stage inputs for the engineering design.

Most of the work conducted at the German pilot plant to date will have been simple batch tests.

I presume the work was conducted by a commercial laboratory that offers specialised metallurgical services, such as SGS. I guess CSIRO is possible. Managed by GR such that they could obtain whatever remaining optimisation data was needed for the engineering design. Yeah, an actual processing line will have been set up.
