Abstract

Sustainability is discussed in the context of the electrical energy that is consumed by the mining industry for the production of everyday metal commodities. The results presented are from a study which attempts to quantify global energy consumption attributed specifically to the comminution processes, namely the crushing and grinding of metaliferous ores. It also reflects on the current understanding of eco-efficient comminution practices, a required mineral processing stage that has received a lot of attention in recent years because of the view that mining is directly and indirectly responsible for up to 45% of the global economy and that a large proportion of the consumed energy originates from the beneficiation processes in the production of mineral commodity.
