Recover Used Gallium From Aluminum

Video description:

In this video we recover the gallium that was used to induce structural failure in various aluminum objects. First, the aluminum is covered with about 10 times its mass in water and a stoichiometric amount (to the aluminum) of sodium hydroxide is added. So for 27 grams we add about 40 grams of sodium hydroxide. This reacts with the aluminum and converts it sodium aluminate. Most of the gallium will remain. Eventually the alloy should liquefy as the gallium proportion increases due to the loss of aluminum. The solution is cooled and the alloy is allowed to solidify. The alloy is then added to 10-30 times its mass of water and heated to near boiling. The remaining aluminum should be consumed by the reaction with water. Once the gallium stops bubbling it is allowed to cool. The gallium obtained has bits of aluminum oxides and slag embedded in it and this can be removed by melting the gallium in a solution of 20% sulfuric acid. Once it is completely molten it is shaken a few times to dislodge the impurities and quickly cooled to again solidify the gallium.
