Abstract:

A process is provided for treating the solid reaction by-products of lithium and sulfur hexafluoride. Lithium in the by-product solid waste is converted to lithium hydroxide. Lithium sulfide in the by-product is converted to lithium hydroxide. Lithium sulfide in the by-product is reacted with an acid to form a water soluble salt and hydrogen sulfide. The hydrogen sulfide is converted to an alkali metal sulfate. Solid aluminum oxide and lithium fluoride are recovered as a feed in the production of aluminum. Remaining lithium salts in solution are converted to lithium carbonate.
