The influence of ore grade decline on energy consumption and …

In 1991, the average energy consumption of two gold mines was 172 GJ per kg of gold, while in 2006, for twenty-two mines investigated, it was 187 GJ/kg (Mudd, 2007a). This close relationship between ore grade and energy consumption has been proven in previous papers (Calvo et al., 2016; Domínguez and Valero, 2013).
