· Furthermore, the “preferred” configurations identified by circuit analysis are not practical for spiral circuits due to large circulating loads and the excessive number of spirals required. Despite the practical shortcomings of recycle streams, the final configuration (Circuit 7) included in Table 1 does appear to merit further study.

· The Humphrey spiral concentrator (HSC) is a widely used mineral separator that sorts particles on the basis of differences in the specific gravities of particles. Since its invention by Ira. B. Humphrey in the 1940s, HSCs have been used over decades in both mineral and coal industry, given their advantages such as low cost, long life, and
