Limonite Iron Ore Dressing Plant

Similar to hematite and specularite, limonite is kind of weak magnetic iron ore and it can be upgraded by gravity separation, intensity magnetic separation, floatation separation and magnetizing roasting. During these methods, gravity separation and magnetizing roasting is used most commonly. Here is some share about the gravity separation of limonite iron ore.

Gravity separation is adopted to upgrade Fe when it comes to limonite iron ore of coarse inlay while for fine limonite granules of smaller than 50 meshes, gravity separation does not work so well. Gravity separation is widely used in medium and small limonite beneficiation factories with its low plant investment, low operation cost, large handling capacity and good beneficiation efficiency. For the same handling capacity, the plant investment is about 1/10 of that for magnetizing roasting processing line.
    
For limonite iron ore, its inlay is usually very coarse and gravity separation is mainly adopted to upgrade. The core gravity separator for limonite ore concentrating is jigger. And it works on basic of density difference between limonite and its attached barren rock to gain limonite concentrate of big density & high grade and barren rock of small density and little iron.

Crushers, vibrating screens, feeders and other assistant will be involved in a whole limonite ore washing line to do the job of beneficiating limonite. Usually, crushing, screening, gravity separation, dewatering shall be included in the limonite iron mining beneficiation line. For crushing, jaw crusher or cone crusher will be used, while circular vibrating screen and linear vibrating screen will be needed for screening, jiggers of different models will be involved for different ores as gravity separators and dewatering screen will be used after gravity separation in dewatering processing.

Limonite iron gravity separation washing line can help to gain good efficiency for limonite ore of coarse inlay limonite granules. The following is about the limonite ore washing plant:

Forui has its own R & D department with indenpendent lab, and a test can be done for your if samples can be available. Forui has been in ore beneficiation and smelting alloy recovery for over 25 years and here we have much to share with you. You are highly welcome here.
