A New Approach to salt cake management

Presently smelters' send their salt cake to third parties for processing or landfill it if allowed. However, this is often expensive and the value of the metal bound up in the cake benefits the third party if they can recover it. Often final disposal of the slag may not environmentally friendly or sustainable. Landfilling this hazardous waste is inceasingly being banned or becoming prohibitively expensive

SALTROMEX technology allows for an in-situ solution, meaning all of the waste salt slag can be treated at your site, recovering the aluminum for re-melt and the flux salts for re use and producing re-salable by products. 

Historically, mechanical methods for metal recovery from salt cake using ball and hammer mills are inneficient and destructive, smashing the metal into fines which cannot then be economically re-melted. And the residual non metallic particles (NMP) are still a problem being reactive and high in salts. 

Ultromex developed the SALTROMEX technology to cleanly separate aluminum metal from the slag meaning recoveries can be of up to 99% of of the metal particles >0.5mm, with little in the way of residual fines. A secondary thermo chemical process then treats the residual NMP to remove and recover the valuable flux salts making them available for re-use, leaving the remaining non metallic oxides non-reactive and odour free. These can be landfilled as inert or non hazardous, or being largely aluminum oxides, become saleable products for use as secondary rescoures in the manufacture of other products.
