LITHIUM-RICH METALLURGICAL SLAG

Title:

LITHIUM-RICH METALLURGICAL SLAG

Document Type and Number:

Japanese Patent JP2021185270

Kind Code:

A

Abstract:

To recycle lithium-bearing batteries, where economic motivation is further enhanced if cobalt and nickel contained in such batteries can be valuated alongside with lithium.SOLUTION: The present invention concerns a slag composition having a high lithium content, suitable as an additive in manufacture of end-user products, or for economical recovery of the contained lithium. The lithium concentration indeed compares favorably with that of spodumene, the classic mineral mined for lithium production. This slag is characterized by a composition satisfying 3%
