gravity separation method of coal washing Description

Mineral processing - Wikipedia

Gravity separation is one of the oldest technique in mineral processing but has seen a decline in its use since the introduction of methods like flotation, classification, magnetic separation and leaching. Gravity separation dates back to at least 3000 BC when Egyptians used the technique for separation of gold.

What Is Coal Preparation? - Energy

What Is Coal Preparation? • Coal preparation is the removal of undesirable material from the Run-of-Mine (ROM) coal by employing separation processes which are able to differentiate between the physical and surface properties of the coal and the impurities. Through coal preparation, a uniform product is achieved.
