Abstract

Procedimiento para la obtención de alúmina de materias primas que contienen compuestos de aluminio mediante descomposición térmica con bases alcalino-térreas especialmente con calcio y lixiviación del producto de combustión con una solución alcalinay especialmente con una solución de soda y sucesiva elaboración en alúmina de la solución de aluminato alcalino obtenidacaracterizado por procederse a la lixivación en presencia de considerables cantidadesde producto ya lixiviado.Procedure for obtaining alumina from raw materials containing aluminum compounds by thermal decomposition with alkaline-earth bases, especially with calcium and leaching of the combustion product with an alkaline solution and especially with a soda solution and successive processing in alumina of the solution of Alkali aluminate obtained, characterized by leaching in the presence of considerable amounts of already leached product.
