Ann: Quarterly Activities and Cash Flow Reports - 31 Dec 2022, page-58

To quote one peer:

"Flotation of low-grade Potash salts is technically challenging & costly". They have since said flotation is uneconomic.

This company had a flowsheet which did not include flotation before KLL listed on the ASX. Clearly they knew something (over 5 years ago) that Kalium didn't.

This company appears to be best placed to weather the problems faced by KLL.
The other companies must be sweating because they have flotation of kainite or schoenite in their flowsheets. AMN made a relevant comment in their quarterly. APC must be nervous.

With relatively few global SOP projects and not all using flotation, can we say that SOP flotation is routine? It didn't look routine at Lake Way and it doesn't look routine at Beyondie. Clearly the guys at Lake Ogden made it work but the Ogden consultants (Corey Milne), helping Kalium (assuming they are involved with the plant) are yet to work their magic.
