Energy Consumption in Mining Comminution

2.1 Energy Consumption in Open Pit/ Underground Mines There is a dearth of information about energy consumption specific to individual mines. One study [6], which is a collaboration that compares seven mine mill/concentrator operations: four gold and three iron ore mines. The average energy needed for seven mines is summarized in figure 2, where

Karara Mining to stack tailings ... - International Mining

If Karara’s iron ore mine had chosen a wet tailings storage facility, the tailings pond would have been roughly 8 sq.km based on its 30-year mine life, according to FLSmidth. The operation is also in the Mid-West region of Western Australia, an area with scarce water reserves, so losing so much water to wet tailings would have been costly to both the environment and Karara’s bottom line.
