Metallurgy
Techniques - Lithium
Carbonate from Indian Lithium bearing mineral -
Lepidolite
Introductin
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.
Major Raw Material
