Abstract

é descrito um processo para a recuperação de alumínio de uma fonte de alumínio reciclado e contaminado com um polímero e/ou um metal não solúveis em um licor caustico, o qual se baseia em separar o polímero, e/ou metal, do alumínio através da dissolução seletiva do alumínio em uma solução de licor bayer, tendo como produtos aluminato de sódio (líquido) e gás hidrogênio (h2 gasoso). ambos produtos podem ser utilizados numa refinaria de alumina, o aluminato de sódio sendo utilizado para a produção de hidróxido de alumínio e o hidrogênio pode ser misturado com o combustível de caldeiras ou fornos.A process is described for recovering aluminum from a recycled aluminum source contaminated with a polymer and / or metal not soluble in a caustic liquor, which is based on separating the polymer, and / or metal, from the aluminum through the selective dissolution of aluminum in a bayer liquor solution, with sodium aluminate (liquid) and hydrogen gas (gaseous h2) products. both products can be used in an alumina refinery, sodium aluminate being used for the production of aluminum hydroxide and hydrogen can be mixed with fuel from boilers or furnaces.
