Explain the gravity separation in ore processing.

Gravity Separation, also known as the Hydraulic Method, operates on the principle of density difference between ore and gangue. This method is particularly effective for purifying oxide ores such as hematite (Fe2O3), an iron ore. In this process, the ore is introduced onto a sloping, vibrating corrugated table featuring grooves. A stream of water is directed over the table.

DMS Processing

High density media separation: The pretreated ore slurry is fed to a DMS cyclone or bath where separation takes place. A thick medium is introduced and the mixture is stirred to ensure even distribution. Mineral separation: As the ore slurry enters the DMS cyclone or DMS bath, the minerals are denser than the media and settle to the bottom.
