Clean Metal Processes is a technologydriven company that has developed recycling technologies and production technologies for Aluminium, Silicon and  Titan.

Al processing

There exist a few available technologies that separates the oxides (AlO3) from the aluminium (Al).

AlO3 reprocessing

White Dross

  • reprocessing of white dross (50% free aluminium)
  • end result around 70% dependent on waste
  • industrialized, ready for launching

Black Dross

  • reprocessing of black dross (below 50% free Al)
  • end result dependent on waste
  • industrialized, but tests needed on specific waste used

FeSi processing

Currently most of the silicon slurry is reprocessed to lower value products, or stored by the wafer producer. This means that there is a potential for increasing the profit for the waste owner.

CMP has developed a cutting edge method for reprocessing of silicon slurry (kerf).  It is a two step continuously model, which  where the processing part is up and running and the cleaning of unwanted material is developed, but need to be industrialized.

SiO2 reprocessing

Silicon Waste to FerroSilicon

  • reprocessing 100% of the Si and SiO2
  • end result depends on waste, but normally 92-97% Si
  • industrialized, ready for launching

Silicon Slurry FerroSilicon

  • reprocessing 100% of the Si and SiO2
  • end result depends on waste, but normally 92-97% Si
  • industrialized, ready for launching

Silicon Waste/Slurry to metallurgical silicon (up to 99,9x% Si)

  • reprocessing 100% of the Si and SiO2
  • cleaning process is developed, needs testing

FeSi Casting alloy from waste

  • industrialized, ready for launching
