Three material streams are reclaimed from salt slag in the RVA process:
  • An aluminium oxide-based material with the trade name, Valoxy®. Valoxy comprises around 70% alumina by weight and is offered as an effective, sustainable, low cost source of alumina for non-metallurgical applications.
  • Aluminium metal in the form of granules. This is returned to the refiners where it is melted as part of a scrap mix.
  • A salt mixture comprising NaCl, KCl and CaF2. This material is also returned to the refiners for re-use as the salt layer in the aluminium melting cycle.
All three streams are therefore put to productive use in a double loop recycling process.
