Spiral classifier is widely used in beneficiation plant to match with ball mill to form a closed circuit circulation path to distribute ore sand. Filter the material powder milled in the mill, and then use the spiral piece to screw the coarse material into the ball mill inlet, and the filtered fine material is discharged from the overflow pipe.
The spiral classifier also named the screw classifier or the spiral classifier machine works as a type of sand classifier or screw sand washer by using the working principle of materials with different particle sizes and weights tending to sink in the liquid at different speeds.
spiral tailings was characterized using XRF, XRD, SEM and screen sieves with the aim of determining the viability of using the wet high intensity magnetic separation technology. It was found that the material had a grind size of 39.20% passing 106μm. The size fraction below 106μm showed the chrome content averaging 33%.

Chrome process equipment is wet type strong magnetic separator, and spiral chute (chrome spiral plant) of gravity separator. 3 Experimental results and discussion 3.1 Chrome magnetic separation process. The chrome raw ore is a flotation tail ore, which is mainly formed in the chromite, and the chromite is the target recovering mineral.
Beneficiation of Iron Ores. Iron ore is a mineral which is used after extraction and processing for the production of iron and steel. The main ores of iron usually contain Fe2O3 (70 % iron, hematite) or Fe3O4 (72 % iron. magnetite). …
Low-grade iron ore received from the West Singhbhum area of Jharkhand state in India was used to develop a beneficiation flow sheet to remove alumina (Al 2 O 3) and silica (SiO 2) from the ore to get iron (Fe)-rich product for steel plants.Mineral characterization showed that the main mineral constituents present in the head sample are goethite, limonite, hematite, …

Most chrome ore must be processed by the chrome ore processing plants. the mainly chrome ore beneficiation method is gravity separation. So the mainly used chrome ore concentrating equipments are ore washbox (sometimes it is called …
In this study, 30% of the total feed solids were above 106 µm. The solids in the fine fraction (-45 µm) accounted for 43%. The middle size ranges (-106 +75µm and -75 +45µm)
Commercial chromite ore beneficiation processes. Pure chromium is difficult to produce since it is readily contaminated by many other elements. Huge quantity of raw chromite ore is being mined and beneficiated in various chrome ore beneficiation plants throughout the world to cater the customized needs of various ferro alloy plants.

Spiral concentrator is one of the simple yet efficient methods of mineral beneficiation which sorts particles according to their specific gravity differences. First commercial spiral concentrator was used to treat chromite ore in 1943. Later in 1943, its use was extended to the mineral sand beneficiation.
Benefication Facilities. Chrome Ore Beneficiation Plant : Chromite Ore fines extracted from the mine is fed into the Beneficiation Plant where the entrenched waste is separated from the ore. Waste is separated by dense medium separation and concentrate material is separated through a spiral centrifugal water process. Fine waste is separated in ...

UG-2 ore about 70 to 80% of the PGMs in UG-2 ores are typically associated with base metals sulphides (BMS) as occlusions and intergrowth [8]. The beneficiation processes are designed to increase the concentration of the PGMs by reducing the bulk of the products from the ore. The mined ore undergoes an MF2
Chrome ore beneficiation Most of the chrome ores around the world are beneficiated by gravity concentration techniques. A conventional chromite ore beneficiation process plant (Figure 3) consist of two sections: Communition (for preparing the material for the subsequent unit operations) Concentration (classification and beneficiation).
