The choice of grinding circuit is based on the density and hardness of the ore to be ground. Although use of the rod or ball mill grinding is quite common, a few facilities use autogenous or semi autogenous grinding systems. Autogenous grinding uses coarse pieces of the ore itself as the grinding media in the grinding mill.

One way to save energy is by blasting more and crushing/grinding less. This way you can reduce the feed size before primary crushing, increasing circuit throughput and reducing the energy required for downstream comminution. Blasting is the most cost-efficient means for ore size reduction. Chemical energy is cheap as opposed to electrical energy.
