Magnetic separation studies for a low grade siliceous iron ore sample

Magnetic treatment of ores and industrial minerals is conducted in both wet and dry modes. The dry magnetic separation process only enables purification where as in the wet process the end product results in the form of slurry. The former especially applies when dealing with material with finer particle sizes. Many mineral.

Recovery Improvement of Fine Iron Ore Particles by . - CiteSeerX

Floc-magnetic separation process is also reported for the processing of fines [26, 27]. Flotation is also used for the beneficiation of finely grained ores [28, 29]. With these conventional methods and depending on the liberation particle size of the ore, significant amounts of fine iron are lost to the tailings [30]. For this reason.
