1011· Removal of unwanted impurities (gangue) e.g. sand, clay etc. from the ore is known as concentration, benefaction or dressing of the ore 1) Levigation: It is the process of separating the lighter gangue particles from the heavier ore by washing in a current of water. This is also called gravity separation or hydraulic washing and is generally used for oxide ores and …

After the milling stage the ore can be further separated from the rock. One way this can be achieved is by using the physical properties of the ore to separate it from the rest of the rock. Prior to any physical separation process, sizing of ore particles is important for effective separation. This is done by using either Industrial Screens or Classifiers. [9] These processes are gravity
