Mining Iron Ore Mining iron ore begins at ground level. Taconite is identified by diamond drilling core samples on a grid hundreds of feet into the earth. Taconite rock comprises about 28 percent iron the rest is sand or silica. These samples are analyzed and categorized so that mining engineers can accurately develop a mine plan.
ABON low speed sizers FLSmidth ABON has been manufacturing low speed sizers since the mid-1960s. The sizers are successful in multiple applications and are often the preferred choice in iron ore, coal and bauxite applications.

57 Abstract The invention relates to equipment for wet magnetic enrichment of minerals, mainly finely disseminated iron ore. Magnetic gidroseparator includes VAT, the supply tank with the main magnet system and a pallet underneath, additional magnetic system made of vertically and radially diverging magnetic plates with clear outer poles of the magnets, the supply and exhaust device.
Sep 16, 2018 The recovery of iron at this time was also improved by introducing fine screens in the mill circuit between the hydroseparators and the finishing magnetic separator. Further development within the mine had also included the erection of a new pumping station on the Trout Lake River, and the completion of the North Perimeter dike.

In addition, of relevance to gravity separation, Dorr-Oliver makes cyclones, MercoBowl R type centrifuges and heavy duty Hydroseparators. Gravity separation. A major use he discovered was controlling the underflow density of thickeners and hydroseparators in mineral-processing systems to thicken or dewater process slurries.
The Top-Service TS Line is the newest generation of Fuller-Traylor Gyratory Crushers from FLSmidth. This entire Gyratory Crusher is engineered from the ground up with Safety and Maintenance in mind.
The Dorr-Oliver machine is a mechanically agitated flotation cell. Two-phase water and air simulations are conducted for a 6 m 3 model of the machine. The overall dimensions of the model are shown in Figure 1. The machine is equipped with a 6-blade rotor surrounded by a 16-blade stator.
FLSmidths Dorr-Oliver Guide Rollers operate on timber or hollow structural steel shaft guides at speeds as high as 40 miles per hour. With an improperly designed or miss-applied Guide Roller any slight misalignment of the guides can cause the conveyance to impact the guides at as much as 2Gs.
