·The past decades have witnessed tremendous progress made in the magnetic separation technology that have significantly decreased the industrial grade of mined iron ore Liu et al 2020 Zeng et al 2019 However the extensive energy consumption and high capital costs required in utilization of low grade iron ore still render it economic unfavorable Wang et al
·Static oil and water cannot form an emulsion and liquid disturbance and strong mixing are the primary reasons for the stable existence of the emulsion [6] The strong shearing effect of crude oil emulsion through valves and pumps and the scouring of high pressure droplets can mix the two phases reduce the droplet size of the dispersed phase in the continuous
·High gradient magnetic separation HGMS is a powerful and useful technique for the recovery of fine weakly magnetic particles Svoboda 2001 and consequently its rotation speed had an effect on the separation performance of CHGMS From Fig 7 the rotation speed of matrix has a very significant effect on the performance An increase in
·Then the interaction effects between the particle size and the material type rotational speed magnetic pole arrangement were investigated It shows that an optimal particle size exists for a specific condition and the separation efficiency of fine particles can be improved by increasing rotational speed magnetic pole number and the
·In this section the effect of magnetic induction on the cDMS performance was revealed through the cDMS experiments with the results displayed in Fig 8 Feed particle size and separation cone speed for the experiments were obtained from their single factor experiments above and the values are − mm and 70 r/min respectively
·Magnetic separation studies are carried out by using high intensity rare earth roll magnetic separator by varying the main process parameters of the separator viz magnetic field intensity of the roll roll speed feed rate splitter position are varied and the findings are discussed in further sections Effect of roll speed on yield and
·Magnetic separation technology is a physical separation method that uses the differences in magnetism between matter to separate them from each other by different motion behaviors in a non uniform magnetic field It is highly efficient green and environmentally friendly with little change in the physical and chemical properties of raw materials Magnetic separation
·High gradient magnetic separation HGMS or high intensity magnetic separation HIMS are the most efficient methods for processing weakly magnetic minerals such as hematite Singh et al 2015 Tripathy and Suresh 2017 ilmenite Yi et al 2023 Yuan et al 2020 Zheng et al 2022 specularite Li et al 2023 limonite Ku et al 2021 Sun et al 2020 tantalum or
·Electromagnetic separation methods mainly including electrostatic separation [5] magnetic separation [6] and eddy current separation are capable of processing mixtures with a wide range of particle sizes appropriate for a wide variety of solid wastes the effects of magnetic roller speed and particle size on the interaction between non
·Magnetic separation studies were conducted on both the as received ore fines and the classified fines to enrich their manganese content and Mn Fe ratio effect of the rotor speed being varied
