Title:
METHOD FOR PRODUCING HIGH-PURITY LITHIUM CARBONATE FROM WASTE SAGGERS
Document Type and Number:
WIPO Patent Application WO/2023/239120
Kind Code:
A1
Abstract:
The present invention provides an optimized method for recovering high-purity lithium carbonate from lithium-containing complex oxides, such as lithium silicate, lithium aluminum oxide, and lithium aluminum silicate, deposited on the eroded surfaces of discarded waste saggers. By using the method for producing high-purity lithium carbonate from waste saggers of the present invention, it is expected that not only can high-purity lithium carbonate which can be used in the production of lithium secondary batteries be produced by recycling discarded waste saggers, but cathode active materials, iron oxide, alumina, silicate, calcium carbonate, etc., which are obtained incidentally during the production process, also can be recycled.
