Gravity concentration Introduction Gravity methods of separation are used to treat a great variety of materials, ranging from heavy metal sulphides such as galena (sp. gr. 7.5) to coal (sp. gr. 1.3), at particle sizes in some cases below 50 txm. These methods declined in importance in the first

Spiral Concentrator - Outotec

Spiral separation uses a flowing film principle based on the size and specific gravity difference present in a mineral suite. When fed a dilute pulp mixture of minerals of different specific gravities, the lighter minerals are more readily suspended by the water and attain relatively high tangential velocities so that they climb toward the outer rim of the spiral trough.
