Liberate aluminum

Morbi nisl eros dignissim nec malesuada et convallis quis augue.

Salt slag is an unavoidable waste product from aluminum smelting and a challenging waste stream to treat and dispose of. However, containing anywhere between 4% and 12 % of aluminum and recoverable salts there is a lot of value contained within it.

Traditionally smelters send their salt slag to third parties for processing. Whilst this solves a problem for disposal it is expensive and the value of the metal benefits the third party.  The final disposal of the slag may well be neither environmentally friendly or sustainable. The Ultromex approach allows for an in-situ solution meaning all of the waste salt slag can be treated in house, recovering the aluminum and the flux salts in the process .

Attempts to treat the material in house to date have been crude, using ball mills and similar downsizing equipment with much of the aluminum rendered into fines and thus lost for re melt. And the residual material is still a problem.

Ultromex has developed a process using a new technology to liberate ductile aluminum metal cleanly from the friable slag meaning recoveries can be up to 99% of of the metal particles >0.5mm, with little in the way of residual fines.

Using in house chemical expertise Ultromex has gone on to on develop an end to end chemical process which treats the de-metalled slag (we refer to this material as NMP), recovering the valuable salts while leaving the treated residual material inert and a useful input for other industries.

The Ultromex technology achieves maximum economic benefits for smelters while being an environmentally sustainable solution for treating salt slag.
