Delineation of gypsum/anhydrite transition zone using electrical tomography. A case study in an active open pit, Altsi, Crete, Greece

Autor: Manoutsoglou Emmanouil, Panagopoulos Georgios, Hamdan Ali Hamdan, George Vachlas

Περίληψη: A well known problem in the grinding procedure, in active gypsum open pits, is the difference of mechanical properties between gypsum and anhydrite. Specifically, the lower stiffness of gypsum compared to that of anhydrite, causes d
