99.9% Grade & 94% Recovery in Germany ! FACT

Juk.  Ok, I get your point, but how about the full Solarworld  PFS from 2014 ?

This 'old' 2009 link show's 99.95 GRADE can be produced specific to Cinovec Czech - https://www.irsm.cas.cz/materialy/cs_content/2009/Jandova_CS_2009_0000.pdf   I stand corrected about the grade being 99.9%.

You challenged me and said lithium recovery would be 73% ( back in 2009 and above link ) and at best 85% ?  I think that is posted on here as a reply ?

The next quote come's from Solarworld PFS , who signed THREE clients up on the back of this :-

"A mica concentrate with 1.13% lithium can be produced at a lithium recovery rate of 94%
(MORGENROTH et al., 2013[63]..
A recovery rate of 90% was determined for further technology and financial considerations."

Looking pretty good to my eyes now ?

Hmmm.... You also said the process from 2009 , the old one,  did NOT include gypsum-lime which is the process which silly old EMH have taken to use at Cinovec ?

Page 169 of the ROASTING PROCESS used by Solarworld PFS :-

"The wet zinnwaldite-gypsum-limestone granules would be dried and roasted for 30 minutes at 1,050°C in a coal dust fired rotary kiln and then cooled down to arround 130°C in a rotary cooling system. The roasting and cooling is a continuous process and converts the lithium
and potassium in the mica to water soluble lithium-potassium sulfate (LiKSO4)
(Figure 59). The iron and aluminum amounts in the mica would be oxidised to water-insoluble oxides. (MARTIN & PATZIG,2014[37])".

I hope this covers some of the doubts you have ?

99.9% grade can be gained , even back in 2009.
Gypsum-lime has already been chosen for Saxony to get the best results from the deposit.

Oh and the "at best 85%" you suggested is actually 94% recovery of Lithium, but they suggest 90% is not too shonky.

I would rather go with the data sets used by Solarworld and as some say those peskey German Companies will look, look, assess, look again and then re assess !  German's are one thing - methodical and would NEVER jump to stupid conclusion's nor would the THREE customers buying ALL the lithium they could produce, back in 2014.

Look's very much like Cinovec will be one hell of a Lithium mine after all.
