The six main steps of iron ore processing
The gravity separation feed range is approximately 30% solid concentration. Process water is used to assist the separation process. The heaviest particles are separated from finer particles by centrifugal force. A collector at the bottom of each spiral collects the heavy concentrate (so-called hematite concentrate) and eliminates the lighter ...

Methods of Separation of Mixtures with Examples
Gravity Separation. We use this process for the separation of a mixture having components of different densities. The powdered mixture undergoes with a stream of running water. The lighter components wash away with water, leaving the heavier ones. For example, a separation of gold particles from rocky substances occurs by gravity separation.
