Inertization of metallurgical residues by stabilization in ceramic products

Objective



This project aims to the development of a new process able to stabilise metallurgical residues like galvanic sludges, electric arc furnace steelmaking dusts, foundry scories and drosses, by their incorporation in traditional ceramic materials, obtaining an adequate inertization of the wastes with minimum losses of properties for the final products. The process and the products will conform to environmental legislation (eco-toxicity characteristics) as well as to actual standardisation for the products. The kind of materials where the wastes will be incorporated are of the clay type, bricks ans tiles being some examples of applications of the inertization technology. Laboratory and industrial testing will be done, in order to optimise the process conditions and to evaluate correctly the process from the economic point of view. Laboratory experimentation will deal with the study of the chemical reactions between clay and wastes phases, as well as to the determination of physical parameters for cooked products, and the resultant eco-toxicity characteristics of the cooked mixture. Industrial testing will be made in traditional brick making lines, the only modifications being those related to the mixture and homogenisation of the whole. It is expected that the project allow to an innovative process, able to be implemented at an European scale, for the stabilisation of a large range of wastes from the metallurgical industry.
