Recovery enhancement of magnetite fines in magnetic separation
An open vertical matrix able to capture 10 ..mu..m (avg. size) magnetite without entraining 2 mm coal has been incorporated in a 1.85 m diameter continuous high gradient magnetic separator. Three-quarter ton samples of magnetite (in 1000 gallons of water) have been recovered with the matrix ring turning at 40 cm/s through a field of 6 kOe.

Magnetic separation has long been used to upgrade and beneficiate a wide variety of industrial minerals. Advances in both wet and dry magnetic separators over the years has broadened their ... abundant magnetite and ilmenite components; however, ilmenite recovery was problematic, hovering in the 17–20% range, because sufficient technology for ...
Conventional magnetic separators are largely confined to the separation or filtration of relatively large particles of strongly magnetic materials. They employ a single surface for separation or collection of magnetic particles. A variety of transport mechanisms are employed to carry the feed past the magnet and separate the magnetic products.
Prussian-blue-modified magnetite (PB-Fe3O4) was prepared by a simple method. The Cs+ sorption ability of PB-Fe3O4 was evaluated by batch magnetic separation. As a result, the maximum sorption ...

This cell separation technique utilizes the potential to label cell surface markers with magnetic bead–tagged antibodies and the ability of a magnetic field to migrate the labeled particles from a distance. 1 This controlled migration by a magnetic force (magnetophoresis) is invaluable in separating heterogeneous cell populations and is the basis for magnetic-activated cell sorting …
Fig 1 Principle of magnetic separation. ... Low intensity techniques are normally used on magnetite ore as an inexpensive and effective separation method. High intensity …
Magnetite was removed from pre-concentrate by using a wet low gradient magnetic separator. Two serially connected magnetic separators were used at this process which has 0.1 T and …
The black sand magnetite is a raw material to produce iron and steel. High content magnetite in the top meter beach sands of the north-west of El-Burullus Lake of Egypt is …
Wet low intensity magnetic separators are widely used for treating fine ferromagnetic or some strongly paramagnetic minerals. The forces acting upon particles in a magnetic separator are magnetic, gravity, hydrodynamic drag, friction, inertia and centrifugal. Relative importance of each force varies with separator design.

Magnetic separation of cells is a simple, rapid, specific and relatively inexpensive procedure, which enables the target cells to be isolated directly from crude samples containing a large amount of nontarget cells or cell fragments. Many ready-to-use products are available and the basic equipment for standard work is relatively inexpensive.
It is suitable for magnetic separation of magnetite, pyrite, roasted ore, ilmenite and other materials with particle size less than 3mm. dry magnetic separator: wide range of mineral particle size, high separation accuracy, no blockage, and power consumption is only 20% of the electromagnetic strong magnetic separator. It is suitable for ...
Magnetic separation is a promising alternative to conventional methods in downstream processing. This can facilitate easier handling, fewer processing steps, and more …

The magnets are either installed as a band around the outside of the separator, inside the device, or into a well in the separator. Some brands …
The magnetic separation process is necessary in order to rid the sample of any metals already within the original sample. Furthermore, metals also react and destroy the heavy liquids by producing a precipitate that is difficult to filter. Procedure This step can either be done before or after the initial roller leaching.
Therefore, magnetite can be separated from a mixture using low-intensity magnetic separation because magnetite particles can get attracted …
