Aluminum dross: aluminum metal recovery and emerging applications

Recycling plays an important role in today's world due to its considerable contributions to mitigating energy concerns and environmental challenges. One of them is dross recycling from aluminum (Al) cast houses. Unlike other recyclable materials, dross has an abundance of components, including rare earth elements, heavy metals, ferrous, and recycled Al. These features make dross a useful commodity within the recycling sector. It is harmful to the ecology and human health to land fill the dross. Recycling dross is economically advantageous and yields products with added worth. This article consolidates the current methods for extracting alumina from dross. The processes of plasma dross processing, acidic and alkaline leaching are critically examined. Dross is used in numerous applications, including the production of hydrogen as a renewable energy source, the manufacture of refractories, composites, ceramics, reductants, catalysts, and absorption agents, as a result of its multi-utility advantages. In construction applications, dross serves a unique purpose by Providing greater strength, thermal insulation and less water absorption increased the desirability of materials in this industry. This study explores the applications that maximize the utilization of dross and the associated advantages.
