Calls For New Brown Coal Projects, page-171

Thanks, and I am aware of that study which I have posted about in the past.
Post #: 26284776

The study tables are around compounds, but my point was around stage 3 and how these compounds become chemicals of saleable scale and quality. The study itself was examining this issue but they described issues around technology and technology development in that regard which IMO were basically their claim that further design work in Stage 3 is required to address the conversion process for the compounds to saleable scale. Hence my comments around stage 3 in my previous posts. Hope that makes sense and what I am referring to in my previous post. I am hyposthesing here so would be good what this PFS actually says.

Now if go to the schematic in this link - http://thermaquatica.com/process-development-unit-pdu/ - you'll see that the fertiliser process in OHD comes before the chemicals/compounds process - stage 1 and stage 2. I suspect the liquor for the plant trials is essentially stage 1 and 2. Now, in the solvent extraction process of OHD, a stripping process occurs that becomes the basis of the chemicals recovery process etc (stage 3) and this is a separate process IMO within OHD to Stage 1 and 2. Apart from the May 9 Ann, which somehow talked about biostimulants whist the study was on chemicals, we haven't been provided IMO any further information on stage 3 and its feasibility and what GPP is doing there and whether there has been any tweaking of the US plant.

As I said, maybe I am missing the point here as minerals is more my strength than agricultural processes.

All IMO
