cobbing process of magnetic separation of iron min

drum separator- an overview | sciencedirect topics

drum separator- an overview | sciencedirect topics

Dry low-intensity magnetic separation is confined mainly to the concentration of coarse sands which are strongly magnetic, a process known as “cobbing,” and is often carried out using drum separators. For particles below 5 mm, dry separation tends to be replaced by wet methods, which produce less dust loss and usually yield a cleaner product… Read more

recoveryof ironfrom cyanide tailings with reduction

Systematic studies indicate that the high recovery rate and grade of magnetic concentrate of iron can be achieved under the following conditions: weight ratios of cyanide tailings/activated carbon/sodium carbonate/sodium sulfate, 100:10:3:10; temperature, 50 °C; time, 60 min at the reduction roasting stage; the liquid to solid ratio is 15:1 (ml/g), leaching at 60 °C for 5 min and stirring speed at 20 r/min at water …… Read more

beneficiation of anironore fines by magnetization

Nov 10, 2017 · Enhancing the magnetism saturation and magnetic susceptibility means that an effective magnetic separation can be achieved. A high grade concentrate containing 65.4 wt% iron with an iron recovery of 92.7% was achieved by magnetic separation with a grinding fineness of 85 wt% passing 38 μm. The results demonstrated that the application of magnetization roasting in iron ore beneficiation was prospective to the efficient exploitation and utilization of refractory iron …… Read more

transformation and separation of metallic iron in reduced

Aug 19, 2020 · The Fe-bearing minerals become magnetite as the corrosion temperature is 100 °C at the oxygen flow rate of 3 × 10 3 L m −3 min −1 for 180 min. 2. When the metallic iron is transformed to lepidocrocite, it is beneficial to the separation of titanium and iron in the corrosion product due to the significant density difference between lepidocrocite and Ti-rich material… Read more

us3672579a - process for beneficiating magnetite iron ore

A process for upgrading low-grade magnetite-containing iron ore with minimum fine grinding. The dry ore is first comminuted to between about three-fourths inch and 10 mesh particle size and magnetically separated. The dry tailing is discarded and the concentrate is ground to between about 20 and 100 mesh and again subjected to dry magnetic separation… Read more

drymagnetic separationof rod-mill feed at minntac

Pilot-plant testing at the Coleraine Research Laboratory has indicated the potential benefits of dry magnetic separation (cobbing) of Minntac rod-mill feed. Therefore, a prototype commercial unit was installed on line 18 to establish the benefits of dry cobbing. Line 18 was operated with and without dry cobbing on alternate days… Read more

major mines & projects | u.s.ironore mine

Following fine crushing, the ore is directed to dry cobbing, which is a dry magnetic separation process used to reject the portion of the ore that does not contain sufficient magnetic iron. The ore not rejected during dry cobbing is sent to a series of wet grinding and concentrating processes to separate, concentrate, and recover the iron from the incoming ore… Read more
