- Iron Beneficiation Spiral Classifier Concentrator For Iron Rec
The first step in all beneficiation plants is converting crude ore into a medium that can be effectively fed into a concentrator. This generally involves some degree of primary crushing, as well as screening or classifying the ores into sizes - either oversized or minus-grade and undersized ores - which were amenable to concentration. At the …

Introduction. The processing of heavy minerals and coal is often carried out using spiral classifiers. Processing of iron ore to separate coarse iron oxides such as hematite from light gangue mineral, such as quartz, is carried out in circuits with several hundreds of rougher, cleaner and re-cleaner spirals (Bazin et al., 2014).

Spiral concentrators are preferred density separation equipment for processing fine-sized particles; typically, finer than 2 mm but coarser than 0.05 mm. Their operation is straightforward, with low capital and operating expenditure. In India, they are used to process iron ores, chromite ores, beach sand minerals, coal, etc.

Spiral concentrator is a gravity separation equipment, consisting of a spiral channel connected to a vertical support. Separation of particles in spirals is based on particle size and density and the combined effect of gravitational forces, centrifugal forces, drag, and Bagnold forces (forces related to Newtonian fluid) on the particles [1,2,3].As …
