More recently, spiral concentrators have been widely used to recover fine coal as well as gold, iron ore and other minerals. The importance of finding the right spiral for your application. For every separation process, there …
Mineral size recovery curves in spirals are calculated using data from two iron ore processing plants.. Recovery of iron carrier particles increase up to 0.2 mm and then decreases due to the Bagnold force.. The decrease of recovery for coarse silica carrier particles is more important than that of iron carrier particles.

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.
