Lithium Apples & Oranges, page-7

lithium carbonate to hydroxide then maybe = 1 / 0.88 = 1.136

I remember reading or hearing what the conversion ratio was from Orocobre itself in the past, but can't remember the exact numbers. There is definitely not much difference between primary grade lithium carbonate input and lithium hydroxide output in terms of mass like there is when converting lithium spodumene to lithium hydroxide, where you get a lot less mass out of the process.
