Abstract
Aluminium and iron can be extracted from materials such as rock, dry soil and dry clays bearing aluminium silicate and forms of iron by dissolving the material in molten sodium hydroxide, preferably in a nickel or iron pot, allowing the melt to cool, dissolving the melt in water, neutralising the solution formed by addition of acid to precipitate aluminium hydroxide [from which aluminium can be recovered by conventional electrolytic processes], filtering to remove the precipitate, acidifying the filtrate with HCI to precipitate iron oxide [from which iron can be recovered by conventional smelting processes]. The aluminium-bearing material may be flint, granite or basalt.
Description
l)c.scription: Aluminum and Iron Extraction from Soil It is quite simple to extract aluminum from nearly all rock clay and soil. Aluminum silicaLCs arc one ol the most common minerals found in the Earth's crust.
Vsint a nickel or iron pot: add sodium hydroxide pellets (as dry as possible) and heat until the alkali becomes a liquid. Add stones such as hint or dry soil, dry clay. ranitc.
b.isalt. .. in small pieces. These will dissolve. Allow the mixture to cool then add pure water. The solution is an alkaline solution olthe components. Add acid until neutral. A white precipitate of Aluminum Hydro.xide occurs. Filter wash then heat to dryness. The resulting Filtrate held in the filter is aluminum oxide (bauxite).
Addition of acid 2M 1-1(1 to the filtrate liquor then precipitates the Iron Oxide this may he washed and dried.
Use the usual process olelectrolysis of bauxite to recover Aluminum Metal. The Iron can be smelted as t.usual.
