The wet high intensity magnetic separation of magnesite ...

The wet high intensity magnetic separation of magnesite ore waste The received sample was subjected to physical, chemical, thermal and phase characterizations. The magnesite ore waste sample contained 77.69 % MgCO 3 and a considerable amount of Fe 2 O 3 (3.14 %).

(PDF) Magnetic Separation of Graphite and Magnesia

Time sequence photograph of magnetic separation observed between graphite and magnesia particles that was observed in a short microgravity condition. Relationship between mass m and χ dia ...

Magnetic Separation of Graphite and Magnesia

An example of magnetic separation observed in the mixture of graphite and magnesia particle is shown in Fig. 1 as a time sequence photograph. The particles were separated into two different groups of material as theytranslatedtowardsthedirectionofdecreasingfield

A study on the separation of magnesite fines by magnetic ...

The magnesite attached to the magnetics might be entrapped to the serpentine aggregates because of the hydrophobic effect. At pH=10 the magnesite particles obtained a magnetic coating, not as strong as that of serpentine, which is why they are attached to the magnetic product . The most favourable pH range for effective separation is 6<pH<9.

Influence of particle size on dry high-intensity magnetic ...

Magnetic separation of magnesite and dolomite was carried out by using induced roll magnetic separator. A magnesite concentrate of 1.12% CaO with 46.02% yield was obtained from a feed of 5.73% CaO. The ore mineralogy reveals that dolomite is associated with goethite, whereas, magnesite is associated with hematite and magnetite.

Magnetic separation of serpentinite mining residue as a ...

Jul 10, 2015 · Magnetic separation was adopted for the present study to obtain a maximum separation of the iron oxide impurity from the feed. The magnetic separation can be either wet or dry, with low or high-energy intensity, depending upon the magnetic susceptibility of the materials to be separated (Bronkala, 1978).

Effect of sodium silicate on the magnetic separation of ...

Anastassakis studied the separation of magnesite fines from serpentine with the magnetic coating method and found that magnetic seed selectively attached to the surface of the serpentine particles but hardly to the magnesite surface at 6 < pH < 11 . Singh et al. used this method to recover iron minerals from Indian iron slimes under the optimized conditions of colloidal magnetite concentration, pH value, and magnetic …

A discussion of magnetic separation techniques for ...

A DISCUSSION OF MAGNETIC SEPARATION TECHNIQUES 201 Low-intensity magnetic separators are utilized to recover any remaining magnetite. The LIMS is followed by a rougher stage of two SLon®-1500 magnetic separators. A third SLon®-1500 magnetic separator is then applied to recover ilmenite in a cleaning stage.

How to Recycle Magnesite Chrome in Copper Smelting Furnaces

Magnetic Separation. The waste refractories contained copper matte, which is comprised predominantly of copper and iron sulfides in solid solution and has a high magnetic susceptibility. Therefore, magnetic separation was used to remove the matte in conjunction with each of …

The Magnetic Separation Study on Flotation Concentrate ...

The magnetic separation results showed that using CRIMM DCJB70-200 laboratory electromagnetic splint VPHGMS is more suitable, and the most suitable operating conditions is the background field strength 641kA / m and bar spacing 2mm, at which time the magnesite concentrate yield was 91.25%, and the Fe 2 O 3 content was 0.34%.

Recovery enhancement of magnetite fines in magnetic separation

Jan 23, 2004 · Thus, fine magnetic particles are usually not picked up effectively by magnetic separators, resulting in the loss of valuable minerals. Magnetic separation applied to ultrafine magnetite particles after size enlargement by polymer flocculation were found to …

US3929627A - Magnetic beneficiation for magnesite ores ...

A process for the beneficiation of magnesite ores includes the selective enhancement of the magnetic properties of the gangue constituents so that said constituents can be easily separated by...

Magnetite Ore, Magnetite Iron Ore, Iron Ore Mining Process

Magnetite - Properties and Applications. Magnetite is characteristically recognised by its strong magnetism, colour and streak. It is commonly used in magnetic separation and coal washing. However, it is not limited to these purposes, as its abundance and magnetic properties means has been used in the production of audio tape, and now more commonly in computer information storage media.

DE102012222434B4 - Magnetic separation of iron from ...

A method of separating iron from ferrous aluminum or magnesium alloy melts, the method comprising: forming a melt (34) comprising molten aluminum or magnesium and impurity iron and containing the iron in the form of iron particles or ferrous Particles (38) is present; a static magnetic field gradient is applied to the melt (34) for a period of time to separate the iron particles or ferrous ...

Magnetic Separation - Washington University in St. Louis

Ferromagnetic minerals are themselves magnetic (i.e., magnetite and pyrrhotite) and can be easily separated from other minerals with a magnet since they will stick to the poles of the magnet. These minerals can be separated by wrapping the poles of a magnet …
