  Production of aluminum chloride from clay using staged reactors - Patent 4213943
The proportions of aluminum chloride and silicon tetrachloride in the effluent gases produced in each stage may be measured to determine appropriate adjustment for the concentration of silicon tetrachloride needed in the feed gas to avoid or minimize chlorination of the silicon oxide in each such stage.
For example, it has been found that the proportions of aluminum chloride and silicon tetrachloride produced during chlorination of clay varies substantially as the alumina content is depleted from the clay.
The mole ratio of aluminum chloride to silicon tetrachloride in the effluent gas decreases rapidly as the process reaches its conclusion.

 Production of aluminum chloride from raw materials containing coal - Patent 3937786
This is probably due to the fact that, in the system to be chlorinated, the raw material containing the aluminum oxide forms a heterogeneous phase with the reducing material, and these two constituents are separated, even after thorough grinding and mixing, with resulting boundary surfaces which deleteriously influence the reactivity and speed of the reaction.
Conversion, referred to aluminum oxide and calculated from the weight of the aluminum chloride obtained, was 54%.

  U.S. Patent: 6004519 - Aluminum promoted hydrogenation of alkylation sludge for aluminum chloride recovery - December ...
The recovery of aluminum chloride from deactivated alkylation catalyst complexes by hydrogenation using hydrogen gas and an aluminum catalyst is disclosed.
Using aluminum to catalyze the hydrogenation allows the reaction to proceed at a lower temperature and pressure while reducing the amount of hydrogen chloride present in the reactor thus reducing the corrosiveness and cost of the aluminum chloride recovery.
After the aluminum chloride is liberated from the sludge complex in a continuous process, it is dissolved in isobutane and is transferred out of the hydrogenation reactor, it is then mixed with an activator such as 1-chlorobutane and additional isobutane to form the active catalyst, and fed back into the alkylator to produce more alkylate.

 Assessment Report - Aluminum Chloride, Aluminum Nitrate and Aluminum Sulphate
Aluminum sulfate can enter the Canadian environment from natural sources in restricted geological environments; however, since aluminum is present in most rocks, dominantly in aluminosilicate minerals, which weather and slowly release aluminum to the surface environment, releases of aluminum from aluminum sulfate cannot be distinguished from other natural aluminum releases.
Aluminum chloride, aluminum nitrate and aluminum sulfate do not deplete stratospheric ozone, contribute to the formation of ozone in the troposphere or influence climate change.
Since aluminum is naturally present in rocks and soil, exposure can occur through inadvertent ingestion of soil on food, from the hands, etc. Aluminum is present in drinking water from natural sources and from the use of aluminum-based coagulants in DWTPs to remove organic compounds, microorganisms and particulate matter.

 Aluminium chloride - Wikipedia, the free encyclopedia
Aluminum chloride is highly deliquescent, and it can explode in contact with water because of the high heat of hydration.
Aluminum chloride, like similar compounds such as Aluminium chlorohydrate, is also commonly used as an antiperspirant.
For both reactions the aluminum chloride (and other materials and the equipment) must be moderately dry, although a trace of moisture is necessary for the reaction to proceed.

 Electrochemistry Encyclopedia --- Aluminum production
Alumina (aluminum oxide) powder, fed to the electrolytic process, is produced by the Bayer process from bauxite ore. Bauxites contain 40-60% alumina, combined with silica (silicon oxide), iron oxide, and titanium dioxide.
Aluminum reduction cells today are of two types: those with prebaked anodes and those with baked-in-place anodes (Soderberg).
Alumina was carbothermally chlorinated to aluminum chloride which was electrolytically decomposed to aluminum and chlorine in bipolar cells with graphite electrodes.

 HistoryOfAluminum - Process
This allowed the first commercial quantities of aluminum to be produced in a plant just outside of Paris.
Furthermore, the price of aluminum, which was initially more expensive than both gold and platinum, would drop 90% over the next ten years, due to the advent of sodium into the process.

 Charles Martin Hall Page
This process was a costly one owing to the difficulty of preparing water-free aluminum chloride from aluminum oxide, the natural source of aluminum, and to the necessity of making sodium metal by chemical means.(1) In the early 1880's aluminum was a semiprecious metal, but Jewett had a sample of it to show his students.
Although the density of solid cryolite is greater than the density of solid aluminum at room temperature, the density of molten aluminum is greater than that of molten cryolite at the electrolysis temperature.
As a consequence, liquid aluminum metal collects in the bottom of the electrolysis vessel where the aluminum is protected from being reoxidized by oxygen in the atmosphere.
