A process for producing alumina and a lithium salt comprising the steps of: (a) calcining an alpha spodumene ore or concentrate to produce beta spodumene; and (b) (I) leaching beta spodumene from the calcining step (a) with an alkaline solution under pressure; or (II) sulphating beta spodumene with at least sodium sulphate and leaching said sulphated beta spodumene to produce a lithium containing solution and a zeolitic residue. The lithium containing solution is treated to provide a purified lithium salt and said zeolitic residue is treated to provide high purity alumina.

Disclosed is an adduct between a Lewis acid, preferably aluminum trichloride, iron trichloride, or zinc dichloride, and a hydrosilane;—a method for preparing same; and a method for for reducing, particularly, an aldehyde, a ketone, an α,β-unsaturated ketone, an imine, or an α,β-unsaturated imine.

Formula (1) where values a, b, c, and d are each greater than 0, and X is at least one selected from the group consisting of CI and Br. A battery according to the present disclosure includes a positive electrode, a negative electrode and an electrolyte layer disposed between the positive electrode and the negative electrode. At least one selected from the group consisting of the positive electrode, the negative electrode, and the electrolyte layer includes the solid electrolyte material according to the present disclosure.

Aspects of the invention include a method of producing a cement material comprising step of: first reacting a calcium-bearing starting material with a first acid to produce an aqueous first calcium salt; second reacting the aqueous first calcium salt with a second acid to produce a solid second calcium salt; wherein the second acid is different from the first acid and the second calcium salt is different from the first calcium salt; and thermally treating the second calcium salt to produce a first cement material. Preferably, but not necessarily, during the second reacting step, reaction between the first calcium salt and the second acid regenerates the first acid.

A method of producing aluminum chlorohydrate comprises adding small form aluminum metal pellets to a reactant receiving space of a reactor tank to form a pellet bed; adding aqueous hydrochloric acid to the reactant receiving space of the reactor tank; and continuously circulating the aqueous hydrochloric acid through the pellet bed. In some embodiments, the continuously circulating aqueous hydrochloric acid dispels reaction gases from the pellet bed. Methods described herein can, in some cases, further comprise consecutively adding additional small form aluminum metal pellets to the reactant receiving space of the reactor tank as the small form aluminum metal pellets are consumed in the pellet bed.

A method of producing particles of aluminum chlorohydrate includes (a) feeding a solution of aluminum chloride through an atomizer associated with a spray dryer, so that a spray of droplets of the solution is formed in the spray dryer, (b) operating the dryer at a temperature sufficient to cause transformation of the droplets into crystal particulates and to dry the crystal particulates, such dried crystal particulates being aluminum chlorohydrate, and (c) recovering the dried crystal particulates. A product produced by the process is also described.
