You are clearly very ignorant of metallurgy and flowsheet development. It's clear that MLL favours a whole-of-ore mill/float circuit over the "conventional" dense media separation (to produce a coarse spod con) followed by mill/float (to produce a fine spod con). It's not the optimal flowsheet in my opinion, but it is less complex. But I digress, to your naive interpretation. It is a necessary evil of flotation, that the ore has to be milled down to 'dust' as you so eloquently put it. Milling is how the spodumene is liberated for recovery in the subsequent flotation step. Without it, flotation is pointless. It's like breathing when you have no brain.

SC6 spod concentrate from flotation has the same sales price as SC6 from DMS so purchasers don't really care.

With regards to sample selection. It would have been preferable to select a sample that matched the current resource/reserve grade but these tests are scouting/sighter tests and provide excellent information to guide future testwork that will inform the DFS. To say the results are null and void for this reason is to not understand the intent and mechanics of testing and feasibility studies.

I would like to see DMS retained in the flowsheet but it's looking increasingly likely that is won't be. The wrong decision in my view.

Good points. Personally I think the sample grade was a fair choice, I've noticed PLS et al use samples in excess of 2% to inform results so I was happy with that.

Crimm says they are testing using permanent magnets to remove iron instead of whims. You happen to know the difference between the two?

Could a simplified flowsheet lead to lower capex? Surely it has to? My thinking is that the reagents used in flotation will increase opex, correct?
