Aluminum Salt Slag Recycling, Spent Pot Liner Recycling & Dross Recovery

Ultromex is a metals technology company offering patented solutions to the Aluminum Recycling Industry.  Our technology is the most effective method for Smelters offering aluminum salt slag recycing, spent pot lining recycling and aluminum concentration from dross.



The new technologies developed by Ultromex for the Aluminum Industry are the new state of the art for smelters seeking to treat:


  • Salt Slag (salt cake) 

  • Spent Pot Liner

  • Dross


Our 2 step process recovers high levels of aluminium from salt slag (salt cake) and drosses, recovers salt for reuse, renders toxic spent pot liners and other non metals into inert materials which can be used in a range of commercially valuable applications. 


  • STEP ONE is a multi-purpose plant, which uses our unique technology to downsize and separate the metal from the non-metallics in dross, spent pot liner or salt slag. The metal is liberated cleanly delivering maximum economic benefit for the operator by leaving the residual non-metallic particles (NMP) suitable for treatment in the second step.


  • STEP TWO is a wet process which separates out the salt for reuse and renders the non-metallics inert for a variety of potential applications including, spent pot liners and reuse in aluminum production.


Our process presents best economic value for Smelters who obtain maximum aluminum recovery, salt recovery and inert residual NMP, which is suitable for a variety of commercial applications. Even better, our technologies are deployed at customer premises, meaning that this material never has to be transported to expensive third parties for processing.
