A static screen is used to divert the fine particles for crushing.
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.
