The washed sand enters a trough and is then pumped to the first stage spiral chute by the sand pump. 4. Gravity separation: The spiral chute can separate heavy minerals from sandy iron and other minerals. The spiral chute produces three outputs: concentrate, medium ore and tailings. Middling may still contain some silica sand.

In the mineral separation process, the ore needs to be ground to a certain fineness so that the useful minerals embedded in fine grains and gangue can be fully dissociated and sorted, and at the same time, excessive …
Flexibility is a key attribute of these plants. Versatility allows for the flow sheet to be adapted to suit specific applications. The heavy mineral plant can be deployed across commodities, including chrome, copper, tin and mineral sands, among others. "The heavy mineral plant can also process both run of mine (ROM) material and tailing dumps.
Classifiers have found wide applications in the mineral processing industry. In this study, a novel enhanced gravity closed spiral classifier is presented. This device uses induced centrifugal force to classify particles. A functional prototype of the separator was 3D printed to experimentally validate the concept. The performance characteristics of the …
In Mineral Processing, the SPIRAL Classifier on the other hand is rotated through the ore. It doesn't lift out of the slurry but is revolved through it. The direction of rotation …

A spiral classifier is shown in Fig. 1.The spiral feed that consists of a water-slurry of ground ore enters the top of the spiral. As the slurry enters the spiral various forces (Burt, 1984) act on the particles to operate the separation between light, heavy, coarse and fine particles.Dense hematite particles slide toward the inner part of the spiral trough where they …
For example, a single-stage spiral circuit was used to replace a complex Reichert cones circuit in the flowsheet treating −1 mm +60 µm iron ore fines at the BHP Billiton Newman beneficiation ...

The spiral classifier is a commonly used equipment for mineral processing (sand washing). It is often paired with a ball mill to form a closed-circuit circulation to divert ore. It is also used in gravity concentrators to classify ore and fine mud, ore slurry in metal mineral processing processes, particle size classification, desliming, dehydration, and other operations in …
The wash-water model (H9000W) is suited for treatment of high-grade feeds, like iron ore, which might benefit from supplementary wash water to remove gangue minerals. Each spiral turn on the H9000W is equipped with our patent-pending wash-water cups.
View ALL our Spiral Classifiers Models. In Mineral Processing, the SPIRAL Classifier on the other hand is rotated through the ore. It doesn't lift out of the slurry but is revolved through it. The direction of rotation causes the slurry to be pulled up the inclined bed of the classifier in much the same manner as the rakes do.
A spiral classifier and a hydrocyclone are the two main classification equipment. For decades, the spiral classifier has been widely used in ore dressing plants as …
4. Concentrate ore filtering system. After getting the minerals to concentrate ore from the flotation system, the high-grade minerals like copper, zinc, lead, and fluorite, use the thickener to concentrate, making higher density. Then send to disc vacuum filter to filter water, and get more dry concentrate minerals. It can dry in the sun or use ...
