water spiral separation specific gravity

Spiral Concentrators — IMSC Group

Principle of Separation. Spiral separation is based on the specific gravity difference present in a feed 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.

Gravity Spiral Chute For Separating Ore

The mineral particles with a small specific gravity are taken away by the water flow, and the ore particles with a larger proportion will be left behind, which means the separation is completed. The spiral chute is an intermittent operation.

US4597861A Spiral separator Google Patents

In wet gravity separation of solids according to specific gravity an outer depleted band partly overlies an inner concentrate band limiting yield and/or purity of separated concentrate. The overlying depletion layer is diverted outwardly from inner wall (15) relative to the concentrate band. Deflection means (20) cause a bow wave in descending slurry which fans out the concentrate aiding

Gravity Method Mineral Processing Spiral Chute

GRAVITY BENEFICIATION PROCESSES Introduction The separation of minerals in a fluid medium (air, water or heavy media) based on their differences of specific density is called gravity separation. Besides specific density, other specifications of particles such as particle size, particle shape, the density of fluid and viscosity values are also

Separation Density an overview ScienceDirect Topics

The most common media for separation is a fine magnetite suspension in water, ferrosilicon suspension, or a mixture of the two, depending on the required separation density. Magnetite alone is used when a density is required in the range from 1.25 to 2.2 g/cm 3,a mixture between 2.2 and 2.9 g/ cm 3,and ferrosilicon alone for a density range

Gravity separation Wikipedia

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.
