Introduction: The three-disc magnetic separator is suitable for precisely separating various magnetic mineral mixed ores. It is mainly used to separate fine-grained weakly magnetic materials from non-magnetic materials, such as ilmenite, monazite, tungsten and tin, tantalum-niobium ore, and other dry separation operations. The induction distance …
magnetic separators. Dry magnetic separation is more controllable since the separation medium is air rather than water. Separating particles from one another is naturally easier without having to fight drag forces created by water. This creates a distinct advantage to using rare-earth dry magnetic separators: the ability to produce a variety of ...
In this study, a three-level Box–Behnken factorial design combined with Response Surface Methodology (RSM) for modeling of process parameters of spiral …
Because chromite is weakly magnetic, with the development of high-intensity magnetic separation technology, the technology of purifying chromium ore with high-intensity magnetic separation has been very mature. ... jig separator or spiral chute separator are the best choices of chrome ore gravity mining equipment. The concentrated ore ...

There are proven and well established widely accepted techniques for concentration of chromite ores such as spiral concentration, jigs and shaking tables. However, these techniques become inefficient and complex when treating fine and ultrafine size particles (less than 75μm) resulting in this size fraction lost to the tailings.
