In modern mining, waste material is often backfilled into underground voids or open pits after the precious minerals are extracted. Such backfill practice has been well adopted in various mining methods, cutandfill (Henderson et al., 1998), sublevel opening stoping (Emad et al., 2015), and open pit mining (Lu et al., 2018).Backfill has proven to be an environmentalfriendly, cost ...

In dry process technology, crushed limestone and raw materials are ground and mixed without addition of water. Dry and semiwet processes are more energyefficient. The wet process requires tons of coal and 110 kWh to produce one ton of cement, while the dry process requires only tons of coal and 100 kWh of energy [4].
