Abstract

This work was conducted to determine the range of variation of the bond index in the ore bodies Yagrumaje Norte and Sur from the Ernesto Ché Guevara Plantsite considering different serpentine-limonite ratios. The cumulative kinetic model was determined for the simulation of the grinding process to allow applying the bond index at industrial scale. The experimental phase was conducted in the pilot plant located in the Investigation Center of the Nickel Industry (Centro de Investigación del Níquel). To complete the test works, the samples were taken directly from the belt conveyors operating at the dryer outlet in the Slurry Preparation Plant. The results indicated basically that the power consumed specifically by the Ernesto Ché Guevara’s mills is to be between 3,4 and 22,4 kWh/t for extreme composition of the materials to be ground. The cumulative kinetic model obtained allows simulating the grinding process at industrial scale under current operating conditions.
