... are reported in this paper. The Monteponi mine is located at the centre of the Iglesias district. Intense fracturing and karstification of the carbonate formations required strenuous efforts to keep the pits dry during exploitation. Here, the underground workings had to be drained at a depth that increased...

... grains. Monteponite (CdO) was named after Monteponi, its type locality in Sardinia, where the mineral was found for the first time in the oxide zone of secondary non-sulfide Zn ores, mainly smithsonite [Zn(CO 3 )] and hemimorphite [Zn 4 (Si 2 O 7 )(OH) 2 ·H 2 O]. The primary Cd-rich sulfide ores...
