Concentration of Ore – Definition, Methods of Separation, Examples

The magnetic ore stays on the belt, while the gangue slides off. By eliminating non-magnetic impurities, this process is utilised to concentrate magnetic ores of iron such as magnetite and chromite and manganese (pyrolusite). A magnetic separator is used in this procedure. A magnetic separator is made out of two rollers and a leather belt.
