El proceso de vitrificación/cristalización controlada aplicado al reciclado de residuos industriales inorgánicos

Abstract

The glass-ceramic process, as well as the usual processing of ceramic and vitreous materials, is being investigated as a promi- sing way for isolation and recycling of both mineral wastes (debris and mineral residues, clearings in public works) and inorganic industrial wastes (muds, slags, fly ashes). Synthetic materials with useful properties to be used as building materials have been prepared from inorganic wastes of different type (red muds from zinc hydrometalurgy, fly ashes from power ther- mal stations, slags and fly ashes from domiciliary incinerators) as well as from mixtures of such wastes with other raw mate- rials. The obtained results allow us to conclude that the ceramic and glass-ceramic processes are outlined as an useful alterna- tive to solve the social and environmental problems associated to wastes production
