Abstract

LA PRESENTE INVENCION SE REFIERE A UN METODO PARA MEJORAR LA CALIDAD DE RESIDUOS SOLIDOS QUE CONTIENEN SILICIO OBTENIDOS TRAS LA LIXIVIACION DEL COBRE DE RESIDUOS QUE CONTIENEN COBRE RESULTANTES DE UNA SINTESIS DIRECTA DE ORGANOCLOROSILANOS. SE ALIMENTA EL RESIDUO SOLIDO, OPCIONALMENTE JUNTO CON UN AGENTE DE OXIDACION, EN UN HORNO FUNDICION EN EL QUE SE FUNDEN LOS RESIDUOS Y FORMAN UNA FASE METALICA FUNDIDA QUE CONTIENE SUSTANCIALMENTE SILICIO Y UNA ESCORIA DE SILICATO CALCICO Y SE CUELAN LA FASE METALICA FUNDIDA Y UNA ESCORIA INERTE DEL HORNO DE FUNDICION.
