Spiral concentrators are used in the iron ore industry to separate heavy iron oxide carrier particles from the light silica ones. Losses of iron occur mainly in the fine (− 75 μm) and coarse (+ 600 μm) size fractions. This paper analyzes the radial distribution of iron oxide and silica particles in the reject of a 7 turn spiral.
The chromite ore must first be crushed and screened into different size fractions. The finely liberated fraction is then mixed with water to form a slurry with a pre-determined density. The feed is then deslimed to remove the ultrafine particles prior to spiral concentration.
