Aluminium Dross Recycling


Ultromex technology to pre treat aluminium drosses for recycling before charging the furnace to increase yields and profits

ALTROMEX enables smelters who are melting drosses to significantly increase throughput, yields, efficiency and profit.

An ALTROMEX plant, optimised for your input streams, is used to pre-treat aluminium drosses for recycling before charging the furnace.  This offers significant benefits for secondary aluminium smelters.

The plant cleanly removes the metal bound with the oxides without loss to fines and with no impact to yields:

Using ALTROMEX to pre treat your drosses in this way means:-

  • More furnace capacity - Increases effciency and throughput
  • Cost Savings - Avoid wasting energy heating on non metal contaminants 
  • Use less flux/create less slag - Having a richer metal mix means less salt flux is required AND therefore much less salt slag waste is produced
  • Increased yields - Our experience shows that pre-treatment in this way increases metal recoveries and crucially, increases your capability to economically accept and treat more drosses - including lower quality drosses not previously considered economic to melt - with your existing melt capacity

Not pre-treating aluminium dross before charging the furnace means that a lot of energy and thus cost for heat, is wasted on the non metallic fraction of the dross waste. That same non-metallic fraction also means valuable furnace capacity is going to waste plus it increases the amount of flux salts required ultimately meaning more salt slag.

ALTROMEX is the solution to increase the metal content of dross before melting enabling smelters to improve the overall efficiency, capacity and profitability of the aluminium dross recycling process. 

ALTROMEX plants use our novel, patented technology as a pre-treatment process for the dross before charging the furnace.

ALTROMEX removes most of the non metal fractions from aluminium dross and, crucially, does this without grinding, milling or crushing meaning that no metal is lost.  

ALTROMEX plants, based on the data we have from plants operating in industry for ~3 years, are low energy and low maintainence.
