Recovery percentage magnetic seperator iron ore

to 85% passing 0.038 mm. The ground iron ore powder was prepared at a predetermined 30% solid content in a stir tank of 5 L volume. As shown in Fig. 1, a drum magnetic separator (RK/CGS- ϕ400 300 ) at a rotational speed of 25 r/min was used for magnetic separation, and the magnetic field intensity was 120 mT. Each time, 5 L slurry was evenly

Apr 20, 2017 Assuming that the amount of magnetic particles dropped by the separator is a nearly constant quantity, a higher percentage of recovery of iron is obtainable from a rich ore than from a leaner ore as the percentage of iron lost is evidently less

Nov 01, 2020 Nov 01, 2020 The magnetic separation efficiency of nickel from the laterite ore was evaluated using the recovery ratio of nickel R ni using the formula: (1) R Ni = m Ni β Ni M Ni γ Ni 100 % where m Ni is the mass of the magnetic product, g; β Ni is the nickel content in the magnetic product, wt.%; M Ni is the mass of the reduction product, g

centration by flotation carried out with a fraction of iron ore made up of the magnetic separation tailing. The study into the recovery of this material carried out in a pilot unit scale had as its main objective, the production of an iron concentrate meeting standards required for commer- cialisation i.e. Fe and SiO2 content of around 66% and

The performance of floc magnetic separation (FMS) has been compared with wet high-intensity magnetic separator (WHIMS). This study was performed

Nov 15, 2016 The recovery of fine iron ore by magnetic separation will decrease with decreasing particle size because the magnetic susceptibility of magnetic particles decreases with a decrease in particle mass. There is an example of an Australian iron-ore operation that introduced beneficiation of fine haematite, -100 m, by using WHIMS2

materials. A magnetic separation for processing iron from fly ash as reported by Prakash successes to remove around 92% iron using magnetic coating at up to 11.8kG.3) Youssef4) reports the magnetic separation of low-grade iron ore by reduction treatment. The iron recovery of 90% was obtained by using wet low intensity magnetic separator and

Moreover, the magnetic concentrates obtained by magnetic separation are composed of relatively smaller particles. However, an opposite trend was observed in the results of this study and was found to be similar to the results obtained by the magnetic separation of iron ore [40,41]

magnetic separation. Dry Magnetic Separation of Iron Ore: There are many inherent advantages in processes that utilize dry magnetic separation to beneficiate iron ore. Wet concentration of magnetite ore, in comparison, re- quires 500 to 1000 gal of water per ton of concen- trate produced. This means extensive use of water

This work presents a semi-smelting reduction and magnetic separation process for the recovery of iron and alumina slag from iron rich bauxite ore. The effect of the process parameters on the recovery rate of iron, maximum particle size of the iron nugget, and the Al2O3 content of the alumina slag was investigated and optimized. The results show that the iron nuggets and alumina slag can be

Oct 04, 2018 Oct 04, 2018 Magnetic Separation and Iron Ore Beneficiation. Magnetic separation is an old technique for the concentration of iron ores and for the removal of tramp iron. Since 1849, a number of patents on magnetic separation have been issued in USA, and texts of some of the patents before 1910 describe a variety of magnetic separators for mineral processing

The studies on hydrocyclone and magnetic separation had indicated that an iron concentrate of 61 - 65 per cent Fe could be obtained by recovering 59 - 78 per cent of the iron values present in the slimes. Depending on the nature of the slimes the alumina and silica levels have been brought down to 2.5 and 1.0 per cent respectively

The coupled process achieved an improvement in the grade of the magnetic concentrate from 52.3% to 59.2% Fe at much the same Fe recovery. This constitutes an improvement in separation efficiency

Aug 08, 2019 Aug 08, 2019 It can be seen that the reductant dosage did not have any significant effect on iron recovery and magnetic yield. However, the iron grade of the magnetic concentrate improved considerably from 56.1% in the feed to approximately 66% at 900 C, and the iron grade improved with increasing temperature
