Abstract

Continuous process for pelleting, condensing and basically stabilizing metals contained in collected dust from the dedusting of smoke in ordinary electrical steelmaking works and foundries, which process consists in that the material can be poured without any type of hazard into a watertight container in which after a period of time the materials take on the consistency and characteristics of a rock, due essentially to reactions of the pozzolanic/lime hydration type with the collected dust.
