"Where did ZEN say that they optimized Pilot Plant flotation to 92.5%? The news release that discussed the Pilot Plant results was September 2014 and no flotation purity number was given" Borne2run
They started Pilot Plant trials after the June delay.
They stated optimized flotation to 92.5% 16th Dec but forgot Pilot Plant which was clearly detailed 3nd Sept that SGS was in the Pilot Plant Stage of Metallurgy.
It goes like this Bench Scale 1st, then Pilot Plant 2nd, then Commercialization on site.
The 2nd Sep NR stated this,
"Additional test work is underway to produce a higher grade flotation concentrate feed to further optimize the purification process and provide extra high purity material for testing by interested parties. This optimization work will provide additional information for the flow sheet
I'll draw you a picture in words, in Sept they reported Pilot Plant Metallurgy, and stressed additional test work to more fully optimize the Flotation at the Pilot Plant level. Then in December they reported a higher optimized Flotation at 92.5%, much higher than the previous 78.3% concentrate (give you a hint, 78.3% refers to last report 2nd Sept.)
So they did what they said, they improved upon Pilot Plant Flotation from 78.3% in Sept to 92.5% in December. I know what you'll say, they didn't mention 78.3% in Sept, but they did in Dec. and they didn't mention Pilot Plant in Dec but they did back in Sept.
Let common sense prevail, cheers, mark
