Suphate price and relationship to hydroxide

In terms of AVZ, from the DFS they are using 153,000 tonnes spodumene to produce 45,375 tonnes sulphate, or in other words 3.38 tonnes spodumene to 1 tonne sulphate (LTR is working of 4.3 tonnes spodumene per tonne sulphate).

So in other words, at a theoretical level:

1. You would probably need 2.22 tonnes of AVZ's sulphate to produce 1 tonne lithium carbonate.

2. 1.92 tonnes of AVZ's sulphate to produce 1 tonne of lithium hydroxide monohydrate (which is what is the input to NCA/NCM batteries (8:1:1 batteries) where LioH.H2O is the input.

1. Lithium sulphate monohydrate has a Li content of 10.85% - or roughly requires around 4.3 tonnes of 6% grade spodumene at a 90% recovery rate - https://www.convertunits.com/molarmass/Li2SO4.H2O. Or in other words around 3.4 tonnes of spodumene feedstock if producing lithium sulphate monohydrate 80% (which conforms to the AVZ DFS conversions which is what AVZ is producing been producing lithium sulphate monohydrate 80%etc).

and

4. Lithium hydroxide monohydrate (LioH.H20) has a Li content of 16.5%, so need about 6.5 tonnes of 6% grade spodumene at a 90% recovery rate. This is generally the 'hydroxide' price quoted at 56.5%

All IMO
