Traditionally, an all-spiral-circuit (Fig. 3) or a spiral-plus-table combination is employed in primary concentration plants (wet circuit) to produce heavy mineral concentrates (HMC). Such equipment operate effectively as long as the ore body does not contain fine sillimanite, kyanite, corundum, garnet, etc.


The Humphreys Spiral has been successfully applied to recovery of chromite from chrome sands, rutile, ilmenite, and zircon from sand deposits, tantalum minerals and lepidolite from their ores, gravity concentration of base metal ores and in the cleaning of fine coal. How it works: Pulp is introduced at the top of the spiral and flows downward.

A wireless, passive embedded sensor was designed and fabricated for monitoring moisture in sand. The sensor, consisted of an inductive-capacitive (LC) resonant circuit, was made of a printed spiral inductor embedded inside sand. When exposed to an electromagnetic field, the sensor resonated at a specific frequency dependent on the inductance of the inductor and its …


The Spiral concentrator has performed better at feed pulp density of 30% by producing concentrate of high grade (93.5%) and with highest recoveries of 96%. The desliming of raw sand has been done using using hydrocyclone. When the deslimed feed is fed to the spiral, high concentrate grades has been produced with very high recoveries as high as 98%.


Spiral Separators for heavy minerals Our gravity separators for heavy mineral applications, including iron ore, chrome, mineral sands and other high density minerals, separate particles in the size range 2 to 0.04 mm. We have a range of spirals, from 3 to 12 turns, with high-, medium- and low-gradient profiles.


The ore is washed through a series of spiral separators to separate the heavy mineral sands from the lighter quartz and clay impurities. The heavy mineral concentrate contains a mix of valuable heavy minerals in different assemblages, as well as residual clays and other non-valuable heavy mineral components and waste.


The optimal circuit can then trans-lated to QASM code, where it is executable on a real quantum device.
