Prospecting, minero-petrographical and physical-chemical characterisation of geological materials; geo-structural analysis of the involved areas; development of mineral treatments finalized to obtain both marketable products and to minimize the content of contaminants and the volume of rejected materials to be confined in suitable sites. Studies on rocks excavation methods for mining, civil, and environmental purposes and on the corresponding technologies for their control and management under safety conditions: development and application of new technologies for the geo-structural and physical-mechanical characterisation aimed at the monitoring and static control of natural cliffside and excavation voids. Rocks cutting and excavation technologies, included innovative technologies like water jet and diamond wire.Valorisation, by mineral processing treatments, and reuse of industrial wastes. Use of natural adsorbents and/or wastes (es. red mud), as materials suitable to immobilise heavy metals and/or to be used in PRB and Filters in order to reduce their migration to the surrounding areas. Characterisation of ornamental stones used in antiquity to identify the extraction quarries.
