Abstract

Si descrive un procedimento per la preparazione di fanghi acquosi a base di argille, non aggressivi verso le argille di strato, che comprende una prima fase di trattamento dell'argilla con una soluzione acquosa contenente la quantità di disperdente necessaria per fluidificare il fango; una seconda fase di separazione dell'argilla così trattata dalla soluzione acquosa contenente il disperdente non adsorbito ed infine una ridispersione in acqua dell'argilla così trattata per la formulazione del fango.
