Abstract

Tumbling mills account major share of power consumption in mineral processing industries. In this paper, an attempt is made to minimize the power consumption in continuous grinding of chromite overburden by improving the grinding performance with different chemical additives. The additives taken are calcium chloride, sodium hexametaphosphate, sodium hydroxide and sodium silicate. It is found that sodium silicate is most effective in reduction in power consumption. The enrichment of nickel in sample is studied with grinding time using the same additives. The rheology of mill is also observed with different additives. In all observations, sodium silicate is found to be most suitable among four additives used.
