Input energy estimation of model minerals. From the estimated Bond grindability work indices sourced from the literature survey for the model minerals (quartz and calcite), the energy input required to reduce the ore sample from 80 % passing feed size (F 80, mm) to 80 % passing product size (P 80, µm) is given by the Bond work index formula as shown in equation (1) (Rowland, 1998).
