I don t think they forgot how to do it .
time to dust it off and bring it back :) to the table.
hpq apollon solar grade silicon project April 4, 2019, Montreal, Quebec, Canada
Apollon Solar is a private French company that, over the past 20 years, has become one of the world leaders in the development of the metallurgical purification steps necessary for the transformation of 1 to 2 N silicon metal ("MG-Si") into solar grade silicon metal ("SoG-Si"), the critical material needed for the photovoltaic conversion of the sun energy into electricity.
CONTINUING THE VALIDATION OF THE INNOVATIVE SOLAR POTENTIAL OF THE PUREVAPTM QRR
Bernard J. Tourillon President and CEO of HPQ Silicon Resources stated: "The December 2017 agreement with Apollon was the final piece of the puzzle in the creation of a world-class technical team. Joining PyroGenesis (PYR-TSXV) and HPQ, Apollon is dedicated to establishing a Low Cost and Green metallurgical approach for the production of solar grade silicon metal (SoG-Si). The extension of the agreement, as we get ready to produce our first 4N+ Purity (99.99+%) PUREVAPTM Silicon Metal (Si) (PVAP-Si) in 2019, could not be better timing, as the identification of the technological clusters needed for the transformation of PVAP-Si into SoG-Si has already started”
