With pressures to improve energy efficiency in mining, reducing energy usage in comminution has become the focus of innovation. Several advances have been made however the uptake of innovations and technologies is slow. A Technology Readiness Level guide has been developed for other industries that may be a useful tool for the mining industry. Examination of selected successful energy efficient technologies provides some insights and lessons that may provide direction for advancing new technologies. This paper presents the present state and future opportunities for innovation to reduce energy usage for comminution. The main focus will be in relation to pathways to shorten the timelines to advance technologies through stages of readiness for commercialization for the risk averse mining industry.
