Lithium Demand surge, page-972

I find this a really useful resource:

http://rocktechlithium.com/lithium-conversion-table/

So to use an example. We take our 6% SC which really means the concentrate holds 6% Li2O. Using the table above the actual lithium content is 0.06 x 0.464 = .0278.

Using the same table the Li content of Hydroxide is 0.165. Therefore 0.165/0.0278 = 5.935x the Li content.

As such I round up to 7 as it is a nice number but also 5.935/7 = 84.8% recovery rates from the refinery. They might fluctuate a bit higher or lower than this but c. 85% recovery tends to be a good rule of thumb.

You can follow the same process for Carbonate.

Hope that helps
