Brief
description/abstract (150 words)
|
The process involves
roasting of ground ore (lepidolite - 2.5 to 4% Li2O) with
alkali sulphate followed by water leaching and subsequently treating
with carbonate salt. The recovery of lithium and purity of lithium
carbonate from this process was obtained as 90-92% and 98%
respectively.
