“…The success of nickel upgrade was determined by the mineralogy of the nickel laterite (Agatzini-Leonardou et al, 2004;Onodera et al, 1987;Narasimhan et al, 1989;Acharya et al, 2010;Zhu et al, 2012;Harris et al, 2011;Tong et al, 2012). Velázquez et al (2008) studied the grindability of a binary mixture of serpentine and limonite components. The breakage rate of the limonite-serpentine blends increased with the increase of limonite content.…”

“…3). Alfredo et al (Coello Velázquez et al, 2008) found that breakage behaviour of each mineral in the mixture did not depend on the mineral content. Therefore, the non-first order was most probably caused by the heterogeneity of the diasporic bauxite, namely, the silicate minerals broke fast at first, and then there was accumulation of stronger fractions in the remaining unbroken material as grinding proceeds.…”

“…In the mining industry, the comminution stage can represent up to 70% of the energy consumed in a mineral processing plant [1][2][3][4][5]. With ball-mill grinding being one of the most energy-consuming techniques, setting the optimal values of the operational and mineralogical parameters for efficient grinding is a key target in mineral processing plants [6][7][8][9][10].…”

The optimization of processing plants is one of the main concerns in the mining industry, since the comminution stage, a fundamental operation, accounts for up to 70% of total energy consumption. The aim of this study was to determine the effects that ball size and mill speed exert on the milling kinetics over a wide range of particle sizes. This was done through dry milling and batch grinding tests performed on two samples from the Penouta Sn–Ta–Nb mine (Galicia, Spain), and following Austin methodology. In addition, the relationships amongst Sn, Ta and Nb content, as metals of interest, the specific rate of breakage Si, the kinetic parameters, and the operational conditions were studied through X-Ray fluorescence (XRF) techniques. The results show that, overall, the specific rate of breakage Si decreases with decreasing feed particle size and increasing ball size for most of the tested conditions. A selection function, αT, was formulated on the basis of the ball size for both Penouta mine samples. Finally, it was found that there does exist a direct relationship amongst Sn, Ta and Nb content, as metals of interest, in the milling product, the specific rate of breakage Si and the operational–mineralogical variables of ball size, mill speed and feed particle size.
