Spiral Concentrator Outotec

During separation, the slurry enters the spiral through a feed box and then flows on to the spiral surface. As the slurry travels down the spiral, mineral grains settle and sort according to size, shape, and specific gravity. Spiral separation uses a flowing film principle based on the size and specific gravity difference present in a mineral suite.

Gravity Separation TiTan Metallurgical Services (TTMS)

Gravity separation uses differences in specific gravity (SG) between various minerals to achieve a separation, and is normally a wet process although examples of dry gravity separators exist. Gravity separation works best when there is a large difference in the SG in the minerals to be separated, and the particle size is similar and not excessively fine, and shape is rounded.

Electrostatic Separation VME

Heat aids gravity separation by reducing the viscosity of the bulk oil phase, thereby allowing the coalesced water droplets to settle to the bottom of the vessel. If the operating temperature of the desalter or dehydrator is too low, the required water settling time is greater, thus increasing the vessel size.

Gravity separation

Gravity separation is an industrial method of separating two components, either a suspension, or dry granular mixture where separating the components with gravity is sufficiently practical: i.e. the components of the mixture have different specific weight. All of the gravitational methods are common in the sense that they all use gravity as the dominant force.
