Role of water velocity for efficient jigging of iron ore
Upgrading of iron ore by jigging has been an emerging trend. Typically -10.0 + 0.15 mm material is considered for jigging where the problem of separation of finer particles is inherent. A detailed investigation is carried out to understand the behavior of various size fractions of the feed material during jigging in order to improve the separation efficiency.
