Aluminium salt slag characterization and utilization A

Aluminium salt slag characterization and utilization A

May 30, 2012 The salt slag recycling process operated by Befesa Escorias Salinas SA enables the recovery of free metal and flux salts, thus creating a product made up mostly of aluminium oxide. The first stage of the process is the mechanical grinding, whose target is the extraction of metallic aluminium from the salt slag and the reduction of particles to an optimum size to ensure the total dissolution of the salts.

Environmental Problems Associated With Recycling

Environmental Problems Associated With Recycling

The salt cake, or dross, that results from recycling aluminum must be disposed of very carefully in order to protect the environment. Engineers have put effort into trying to figure out different ways to solve this problem. One way is to reduce the amount of salt cake that is produced during the recycling process.
