Abstract
The characteristic functions of the various elementary phases of the overall extraction and treatment process are identified and the limits and advantages of various possible alternative design solutions are discussed. In this way the conditions for modeling the extraction and treatment process are defined, the following phases being analysed: -characterization of the raw material deposits with respect to mineralization variability, -identification of alternative mining methods with respect to production process flexibility and consequent sequence of the "production units" and their characteristics (deplation project), -choice of prehomogenization and homogenization systems and to reduce variability in characteristics of raw material flows, -influence of variability of raw material characteristics treatment process. The study deals particularly with problems concerning the extraction of the economic mineralsI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
