2021-5-5 Power saving comes in the form of energy required to reduce the ore to the required recovery particle size. “Apart from the reduction of equipment prior to the mill, the VRM uses a particle-on-particle crushing milling principle. This means that all the power used is put into this phase and not into moving around grinding media.

In investigating iron ore in an open cut mine, it was reported that there was potential to reduce the mining costs (based on energy savings) by 36% and milling costs by 47%. For gold mining this estimate was reduced to a staggering 53% for milling. Examples of Energy Events

This can mean reduced fuel consumption but increased electricity consumption because it can take over 20,000 hp to move the tens of thousands of tonnes of material a day to the mill. The overall energy consumption goes down but the capital expenditures can only be justified for large quantities of ore.
