New Dry Recycling System for Aluminium Salt Cake from BHS

A simplified dry recycling process to recover the 5-10% of aluminium which remains in the aluminium salt cake produced in the smelting process of secondary aluminium, has been developed by German recycling equipment manufacturer, BHS-Sonthofen. According to the company, to date the recovery of this aluminium has thus far proven difficult, costly and time consuming.
