Gravity Spiral Concentrator Working Principle

The Humphreys Spiral Concentrator is a simple, efficient gravity concentrator which effects a separation between minerals of the proper size range that have sufficient difference in their specific gravity. This concentrator is a spiral conduit of modified semi-circular cross-section, with outlets for removal of concentrate and middling. Pulp is introduced at the top of the spiral. As the pulp follows

Spiral Concentrators — IMSC Group

As the most simple gravity separation technology, and arguably the most efficient, spiral concentrators have long played an important role in minerals processing. The spiral concentrator is one of the most effective, low-cost devices for the gravity beneficiation of ores. Manufactured from lightweight, corrosion and abrasion resistant materials, spirals require a minimum of maintenance and upkeep. Spiral

Spiral (Concentrators) - an overview

By the 1950’s, spirals were the standard primary wet gravity separation unit in the Australian mineral sands industry. In the spiral concentrator the length of the sluicing surface required to bring about segregation of light from heavy minerals is compressed into a smaller floor space by taking a curved trough and forming into a spiral about a vertical axis.

Gravity Separation - ttms999

Spirals are commonly used to separate sand sized particles with moderate SG differential in the range -2mm +75um, although varieties exist that can separate reasonably efficiently down to 63um. Below this size range efficiency falls off rapidly, and enhanced fine gravity separators are generally required.

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. At the same time, the heavier, non-suspended

A history of gravity separation at Richards Bay Minerals

Quartz was upgraded in the non-conductor fraction and gravity separation was required to overcome this. The original gravity circuit consisted of two stages of wash-water spirals and two stages of shaking tables. The spirals employed were Roche WW2A and WW2B double start spirals identical to those employed in the feed preparation gravity circuits.

Spiral separator - Wikipedia

For good separation, the density difference between the heavy minerals and the light minerals in the feedstock should be at least 1 g/cm 3; and because the separation is dependent upon size and density, spiral separators are most effective at purifying ore if its particles are of uniform size and shape. A spiral separator may process a couple tons per hour of ore, per flight, and multiple flights may be stacked in
