Recuperation et Valorisation de L’Aluminium (RVA) has developed a 70% Al2O3 material for application in a range of key markets, including ceramics, refractories, cements and mineral wool.
The material, branded Valoxy, is derived from the processing of salt slag, a waste product from secondary aluminium smelting.
Howard Epstein, consultant to RVA, told IM: “Valoxy is considerably cheaper than bauxite or alumina. Moreover, RVA offers stable supply and long term price stability.”
“RVA is now seeking partners with specific competences from the alumina/bauxite industries to maximise the potential offered by Valoxy’s aluminium oxide content. The current evaluation and market research phase is estimated at three months,” said Epstein.
Based at Les Islettes, 200km east of Paris, RVA was established in 1989 to mill salt slags and sell the derived aluminium granules. Recycling of the salt residue was initially an environmental requirement and...
