In milling operations, comminution, i.e. breaking of ores into smaller particles for liberation of target minerals is the most energy consuming process. Conventional comminution including crushing- semi-autogenous grinding circuits account almost 30-40 % of the overall energy consumption in mines. For large copper, such those found in British Columbia, comminution uses about 70 % of all electrical energy consumed. The Canadian Mining Innovation Council have identified energy efficiency as one of their key target areas for research in the mining industry. The proposed research is aimed at advancing an energy efficient technology which can significantly reduce energy use in minig.

在研磨操作中，粉碎（即将矿石破碎成更小的颗粒以释放目标矿物）是最耗能的过程。包括破碎-半自磨回路在内的传统粉碎几乎占矿山总能耗的 30-40%。对于大型铜矿（例如不列颠哥伦比亚省发现的铜矿），粉碎过程消耗的电能约占所有电能的 70%。 加拿大矿业创新委员会已将能源效率确定为采矿业研究的关键目标领域之一。 拟议的研究旨在推进一种节能技术，该技术可以显着减少采矿业的能源使用。
