    Jig concentrators are continuous processing gravity concentration devices using a pulsating fluidized bed The first pair of electromagnets was weakly magnetised and served to draw off any iron ore present The second pair were strongly magnetised and attracted the wolframite, which is weakly magnetic These machines were capable of treating 10 tons of ore a day This process of separatingOur Gravity Concentrators: Gravity Concentrators for Heavy Minerals Our mineral gravity concentrators separate fine heavy mineral particles from 15 to 004 mm, and are ideal for iron ore, chrome, mineral sands and high density ores Their compact nature and relatively low height provides a low footprint classification solutionGravity Concentrators Multotec | Mineral ProcessingWhen the iron ore is extracted from the mine, it must undergo several processing stages Six steps to process iron ore 1 Screening We recommend that you begin by screening the iron ore to separate fine particles below the crusher’s CSS before the crushing stage A static screen is used to divert the fine particles for crushing This stepThe Six Main Steps of Iron Ore Processing | Multotec
