Fluxes are special blends of typically solid, inorganic compounds designed for degassing, demagging, cleaning, grain refining, and/or chemistry modification of molten aluminium alloys and other purposes. Fluxes are usually added during the melting, holding or degassing of aluminium to furnaces, crucibles, ladles, or other aluminium vessels.

Pour the molten aluminum into steel molds. You can let the aluminum ingots air cool and then dump them out of the molds, or use water to speed up the process. To water cool the aluminum, take your tongs and place the ingot and mold into water for about 10 seconds. After soaking in the water, the ingot should be cool enough to touch.

After the ore has been concentrated it must be roasted to a high temperature allowing for the desired metal to be oxidized. Once the metal is oxidized it is reduced by a reducing agent. Reduction may require the metal oxide to be heated at a high temperature. The metal must be further refined to remove all of the impurities that it may contain.
