EstablishedMother liquor, milligrams per cubic decimetre: Li 30, Ca 144.4, K 142.1, Na 76.9, Al 26.7, Mg 1.235, Fe 0.036. The four largest impurities together exceed the lithium roughly thirteenfold.
Measured at this deposit
In the liquor that 93.3 per cent of the lithium reached, lithium is the minor constituent: at 30 milligrams per cubic decimetre it is outweighed by calcium at 144.4, potassium at 142.1, sodium at 76.9 and aluminium at 26.7 — so a high extraction yield produced a dilute and impure solution, not a lithium product.

EstablishedDownstream of the leach liquor: nothing performed. Lithium carbonate production and impurity precipitation both stated as further studies.
Reported for this deposit
No lithium compound was produced from the Kırşehir liquor and no purification of it was performed: the study states that making lithium carbonate from the mother liquor, and precipitating out its iron, aluminium, magnesium, calcium, sodium and potassium, are matters for further work.

EstablishedLithium extraction 93.3 per cent, at a roasting temperature of 1000 degrees Celsius for 90 minutes with a concentrate to gypsum ratio of 5:6, followed by water leaching at 40 degrees Celsius for 90 minutes at a water to solid ratio of 5:1. Laboratory scale.
Measured at this deposit
Roasting the Kırşehir zinnwaldite concentrate with gypsum and then leaching the calcine in water took 93.3 per cent of its lithium into solution, at laboratory scale.
