A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints. Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles ...

Introduction. As coarse grained, easily processed ore bodies are depleted, more disseminated, finegrained ores are being treated. Adequate liberation of valuable components within a finegrained ore is often only achieved once the particle size of the ore has been reduced to levels below the traditional ball mill cutoff of 45. μm.. To aid in the economic liberation of finegrained minerals ...

iron ore is expected to rise by more than 200 million tonne per year to meet the internal demand export. This additional requirement of iron ore will need beneficiation of low grade ore/fines to get the major portion of increased demand. This paper deals in brief to use of available methodologies for beneficiation of iron ore in Indian context.
