The spiral classifier can form a closed loop with the ball mill in the beneficiation production line to control the particle size of the material, separate ore sand and fine mud in the gravity …
In the present paper, response of a low grade hematite-goethitic iron ore to beneficiation for the production of sinter and pellet feed material has been investigated. The ore sample contained hematite as the major iron bearing mineral with considerable amount of goethitic material. The major impurities present were quartz and clay.
Generally speaking, the equipment investment cost of the spiral classifier is higher than that of the hydrocyclone. The classifier equipment cooperates with the ore grinding equipment in the beneficiation production line …
Present investigation includes the magnetizing roasting of low-grade iron ore fines followed by grinding and beneficiation using magnetic separation. The hematite iron ore used in the investigation contains 53.17% T Fe, 10.7% SiO2, and 4.5% Al2O3. Powdered bituminous coal of 210 μm size with an ash content of 12.5% and fixed carbon of 54.25% was used as …

According to the size of the grain size of hematite in the ore, the beneficiation process of hematite can also be divided into the following ...
Beneficiation studies were planned as gravity cum magnetic separation based on mineralogical characterization studies. The design of experiments consisted of beneficiation at a coarser size using scrubber, classifier, jig and two-stage spiral separators as rougher and cleaner after screening and crushing of the feed sample to below 6 mm.
Ore that is less than 40 mm but greater than 8 mm is conveyed to the lump stockpile. Ore that is finer than 8 mm, but greater than 1 mm is conveyed to the fines stockpile. Any ore that is finer than 1 mm in size is conveyed to a de-sanding plant consisting of cyclones, upper current classifiers and two stages of spirals for further beneficiation.
DOVE Spiral Classifier, also referred to as Screw Classifier, or Spiral Mineral Separator, is highly efficient classifier designed for closed circuit wet classification and separation of the Slimes (Fines) from a sandy sized (Coarse) material. It is well suited for classification, where a two product size-split is required. Due to inherent operational qualities, DOVE Spiral Classifier is ...
Common spiral classifiers can be classified according to the overflow height, that is, the position of the spiral in the water tank is different from the height of the pulp surface. The spiral classifier can be divided into three types: high dam type, low dam type and submerged type. 1). High Dam Spiral Classifier
