The supply chain for metals used in manufacturing is usually from premanufacture (mining). Energy impact needs to be considered, with it being one of the five stressors that impact the environment.

The industrial comminution process under consideration has the following four units: Rod mill, Ball mill, hydro-cyclones, and water sumps. Fresh feed from the bin is fed to the rod mill along with water. The slurry generated from the rod mill is mixed with the slurry from the ball mill in a primary sump.
