Secondary aluminum production has several advantages over the primary aluminum production, such as resource conservation and energy savings. For these reasons, aluminum is one of the most recycled metals worldwide. During secondary aluminum production, dust containing aluminum is generated in many stages, and it is usually landfilled in US. However, a proper handling of aluminum dust is required since it has flammable and irritant nature. In this research, aluminum recovery from the secondary aluminum production dust is investigated by hydrometallurgical processes. First, sodium aluminate solution is generated by sodium hydroxide leaching of secondary aluminum production dust. After that, aluminum in the leach solution is recovered as the aluminum hydroxide by adjusting the pH of the solution. Based on the results, the percentage of aluminum recovery from the leach solution is about 94% at pH 10.5.
