A Study of Stabilization and Recycling for Aluminum Dross

In this study, a recycling process for stabilized secondary aluminum dross is proposed. Calcium oxide-containing materials, such as de-sulfur slag produced from steel manufacturing process, are used as stabilizing agents for secondary aluminum dross. The de-sulfur slag was first hydrolyzed. Due to the high content of calcium oxide (about 45%), hydration of de-sulfur slag can produce a solution
