“ WE ’ VE HAD A GREAT RESULT AT SAN JOSE – - A NET PRESENT VALUE ( NPV ) IN EXCESS OF US $ 720MN AND AN INTERNATIONAL RATE OF RETURN ( IRR ) OF 51 %”

— Ryan Parkin , CEO , Infinity Lithium
49 largest lithium plant at the Kemerton Strategic Industrial Area - also set to become the largest lithium hydroxide plant in the world . Ledoux Pedailles maintains Infinity is geared towards entering production as quickly as possible ( by 2022 ) using equipment available today , and is not looking to reinvent the wheel using new technology .
Allied to that mission , the company is keen to embrace an environmentally friendly process : “ Mining is viewed negatively in terms of the environment so with our process we have decided to go down a different route to the one currently used in China ,” explains Ledoux Pedailles . “ In Asia , ore is processed into lithium chemicals using thousands of tons of sulphuric acids at prolonged high temperatures during the roasting and leaching process . Infinity will instead apply the proven sulphate process at San Jose and not employ any sulphuric acids . We ’ ll be using a sodium sulphate or potassium sulphate in our roasting process , which are safe chemicals and available domestically . The roasting process only goes up to 850 degrees
