In coming years, global lithium production is expected to increase as the result of widespread electric vehicle adoption. To meet the expected increase in demand, lithium must be sourced from both brine and hard-rock deposits.

Keywords: Floatex density separator, Iron ore processing, Simulation, Slip velocity Introduction A significant amount of fines is generated during mining, processing and handling of iron ore as Indian haematitic and lateritic iron ores are soft and friable in nature.1,2 These fines are rich in alumina and silica and hence poor in iron content.
As the primary beneficiation method for iron ore, magnetic separation improves ore grade, reduces silica and harmful impurity content, and facilitates the smelting process [28], [32], [33]. Utilizing magnetic separation is an important step towards achieving green and low-carbon steel production.
Our gravity separators for heavy mineral applications, including iron ore, Chrome, mineral sandsand other high density minerals, separate particles in the size range 2 to 0.04 mm. We have a range of spirals, from 3 to 12 …

The paper discusses various aspects of the application of heavy-medium separation to the processing of hematite ore at Sishen and Thabazimbi. The two main factors to be borne in mind in the design of a plant for such beneficiation are the Iow unit value of the iron ore produced and the high separation densities required.

As shown in Figure 13.2, minerals with ferromagnetic properties have high susceptibility at low applied field strengths and can therefore be concentrated in low intensity (<~0.3 T) magnetic separators. For low-intensity drum separators (Figure 13.11) used in the iron ore industry, the standard field, for a separator with ferrite-based magnets, is 0.12 T at …
Fe % decreases with a lower drum speed. However, it is also observed that to settle heavy-density particles, large amplitude is required. Therefore, if the stroke length changes visa-a-vis drum speed, a sharp decrease in grade is found to be prominent . Apart from MGS, Kelsey jig and Knelson concentrators were also used for treating iron ore.
