Monitoring, modelling and simulation of spiral concentrators
Spiral concentrators are robust gravity separation devices often compactly implemented in industry with large amounts of spirals per plant – organized in banks. Current automated monitoring strategies at spiral concentrator plants involve quantifying overall feed and product stream states. However,Case study: high capacity spiral J concentrators,Spiral concentrators are compact, cost-effective and generally efficient gravity concentration separators for a wide range of applications (for example: coal, beach sands, iron ore, chromite and tantalite). Large mineral processing plants consist of thousands of spiral concentrators resulting in large plantData Sheet - MG12 Rev: 1 MG12 vs MG6.3 (Recovery),concentrator plants that are greatly simplified and capable of higher overall metallurgical performance. Conventional flowsheets containing five, six or more spiral stages may be replaced by a three stage MG12 flowsheet that will provide superior metallurgy. InSpiral (Concentrators) - an overview | ScienceDirect Topics,The spiral concentrator applies differential density separation between particles to separate the valuable minerals from the gangue minerals. They have been widely utilized in coal washing plants worldwide to treat material in the particle size range 1 mm–150 μm (other reports show that spirals are capable of treating material down to 45um).Spiral Concentrator | Multotec,Spiral concentrators are simple low energy-consuming devices used for mineral separation mainly on the basis of density or by shape. Spirals are widely used in mineral processing as a method for pre-concentration and have proven to be metallurgically efficient and cost-effective.Heavy Mineral Spiral Concentrators,Heavy Mineral Spiral Concentrators Gravity separation of fine heavy minerals in the size range 1.5 to 0.04 mm may be conducted on spiral concentrators.
