In terms of processing material size, the gravity separation method can process materials as small as 0.01 mm, such as tungsten ore, tin ore sludge, and can also process materials as large as 200 mm, …
Spiral Concentrator
Spiral Separators for heavy minerals. Our gravity separators for heavy mineral applications, including iron ore, chrome, mineral sands and other high density minerals, separate particles in the size range 2 to 0.04 mm.. We have a range of spirals, from 3 to 12 turns, with high-, medium- and low-gradient profiles.
Physical separation of iron ore: magnetic separation
Gravity separation also has the advantage of low operating costs, but it is often implemented at a much smaller scale compared with magnetic separation. In summary, magnetic separation should always be given priority when designing iron ore beneficiation flow sheets.
