Disclosed is a method for leaching lithium via an electrochemical apparatus including a multi-functional current collector, an electrode, an electrolyte, and a lithium-bearing material, wherein the lithium-bearing material is dispersed or suspended in the electrolyte or the lithium-bearing material is coated onto the current collector. The method involves applying voltage to the current collector to leach lithium from the lithium-bearing material. The method can involve adding promoter additive into the electrolyte to boost lithium extraction within the electrochemical apparatus.

Described herein are methods for recovering lithium metal, lithium hydride, or lithium hydroxide from lithium salts by dissolving the lithium salt in ionic liquids and applying a current to the solution.

A method and system for producing cement using electrolysis is presented. Via an electric current, an electrolysis process may be performed on a melted oxide material, which may be anorthosite.

Described herein are methods of recovering lithium from aqueous sources. The methods include extracting lithium from an aqueous lithium source using an extraction stage to yield a lithium intermediate; routing the lithium intermediate to a concentration stage to yield a lithium concentrate; and adjusting parameters of the ion withdrawal extraction stage to target a ratio of lithium ions to impurity ions in the lithium intermediate.

The invention is directed to a method of preparing NH.sub.3, and to a method of regenerating a metal M from MOR.sup.1, wherein O is oxygen and R.sup.1 is CH.sub.3 and/or C.sub.2H.sub.5. The method for preparing NH.sub.3 comprises the steps of a) reacting a metal with nitrogen gas to produce a metal nitride, wherein the metal is selected from the group consisting of Li, Be, Mg, Na, Mo, Al, Zn, Ca, Sr, and Ba, b) reacting the metal nitride obtained in step a) with R.sup.1OH to produce NH.sub.3 and MOR.sup.1, wherein R.sup.1 represents CH.sub.3 and/or C.sub.2H.sub.5, and c) regenerating the metal by electrolysing said MOR.sup.1 under formation of HCHO and/or CH.sub.3CHO. The method of regenerating a metal M from MOR.sup.1, comprises electrolysing of MOR.sup.1 under formation of HCHO and/or CH.sub.3CHO, wherein R.sup.1 represents CH.sub.3 and/or C.sub.2H.sub.5.
