The Humphreys Spiral Concentrator consists of a spiral conduit of modified semicircular cross section. Ore pulp is fed to the top and, as it flows downward, the heavier particles concentrate in a band along the inner side of the pulp stream (Fig.
SINCE it was introduced in 1943 to recover chromite from Oregon beach sands, the Humphreys spiral concentrator has proved successful in several fields of wet mineral beneficiation. By the …
The spiral concentrator first appeared as a production unit in 1943 in the form of the Humphrey Spiral, for the separation of chrome-bearing sands in Oregon. By the 1950's, spirals were the standard primary wet gravity separation unit in the Australian mineral sands industry.

SINCE it was introduced in 1943 to recover chromite from Oregon beach sands, the Humphreys spiral concentrator has proved successful in several fields of wet mineral beneficiation. By the end of 1957, 9390 Humphreys spirals had been manufactured.
In 1944, the Humphreys Gold Corporation (later renamed Humphreys Mining Company) installed 192 spirals near Jacksonville, Florida. The operation mined ancient beach sands and produced ilmenite and rutile-sources of titanium.
Development of spiral concentrators started in the early 1940's with the introduction of the Humphreys spiral. This was initially used in the processing of chrome-bearing sands but rapidly found applications in the treatment of beach sands containing other valuable, heavy minerals.
