Lithium Carbonate from Indian Lithium bearing mineral - Lepidolite

Introduction

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

Leoidolite, Alkali Sulphate, Carbonate Salts, Water, Steam etc.

Major Plant Equipment

High temperature continuous furnace, constant stired tank reactor, solid-liquid separator unit.
