Gravity/Density Concentrator, Spiral Concentrator Academic
A concentration criterion (CC) can be used for gravity separation possibility as in following equation: CC = {phPflUid)l (р i РрМ) ph is the density of heavy material, pt is the density of light material, and pflujd is the density of fluid medium (water/air) If CC >±25, gravity separation is relatively easy
Mineralogy of beach sand in Jumundo, Korea and recovery of
The Ilmenite was concentrated with a Humphrey spiral concentrator and shaking table followed by magnetic separators (drum and cross belt types) As a final product, 18% of the Humphrey spiral system concentrate was recovered, and the grade of final product was determined to be 93% ilmenite
