differences and applications of magnetic separation and froth flotation | fote machinery

The magnetic separator is the key beneficiation equipment for separating magnetic minerals from non-magnetic minerals or minerals with magnetic differences. The process is based on the different components in the separated materials, which means that in the working magnetic field, the different magnetic field forces and other forces received by different particles are used to separate different materials.

Froth flotation machine is generally used for the concentration of sulphide ores. The principle behind froth flotation process is that sulphide ores are preferentially wetted by pine oil whereas gangue articles are wetted by water.

In this process, the suspension of a powdered ore is made with water. Collectors like pine oil, fatty acids and xanthate are added to it. Froth stabilizers like wrestles and any line stabilized the froth. The mineral particles become wet by oils while gangue particles by water.

A rotating paddle agitates the mixture and draws air in it, as a result, froth is formed which carries the mineral particles. The froth is light and skimmed off, and it is then dried for the recovery of the old particles.

In order to realize the separation of different minerals through magnetic separation, it is necessary to ensure that there is a relatively obvious difference in force between different magnetic materials, especially the difference in magnetic field force.

Minerals in nature, due to their different atomic structures, exhibit different magnetic properties under the action of a magnetic field, and different minerals exhibit large magnetic differences.

Minerals are divided into non-magnetic minerals, weak magnetic minerals and strong magnetic minerals. Among them, strong magnetic minerals are the least. There are dozens of weak magnetic minerals, while non-magnetic minerals are numerous in variety.

Of course, the strength of magnetism between minerals is relative, and it is relative to the strength of the external magnetic field. With the development of magnetic separation technology and magnetic material technology, its definition has always changed.

After crushing to less than 70 mm, the ore need to be washed, sieved and classified, firstly got material with + 30 mm needs manual beneficiation, then 4.5-30 mm ore is dressed by jig, and last ore with -4.5 mm should be processed by roller-type strong magnetic field magnetic separator.

Wolfram ore coarse concentrate magnetic separation process: before separation, the material is crushed to-3 mm by roll crushers, then they are screened into three levels which are 0.83 ~ 3 mm, 0.2 ~ 0.83 mm and 0 ~ 0.2 mm, and finally you can get wolframite concentrate by magnetic classification beneficiation.

Crystalline graphite has good natural floatability, so froth flotation would be best for processing it. Since the size of graphite flakes is one of its most important quality indicators, a multi-stage grinding and multi-beneficiation process is adopted to remove large flake graphite as soon as possible.

Copper is the main valuable recyclable element in ore, and its content is 0.77%. Copper ore contains lightly oxidized sulfide ore, and the copper in the ore is mainly in copper sulfide minerals. For copper ore, there is 0.45% of primary copper sulfide, accounting for 60.57% of the total copper; secondary copper sulfide 0.27%, accounting for the total copper 36.34%; free copper oxide and combined copper content is relatively less.

The recoverable copper in the ore is mainly stored in chalcopyrite, chalcocite and a small amount of copper-bearing sulfide minerals such as copper blue and azurite, with a copper content of about 1.72%.

wet high intensity magnetic separator

wet high intensity magnetic separator

Wolframite minerals, being weakly magnetic with a specific susceptibility of 3910 -6 to 4610 -6 cm/g, can be effective separated from cassiterite and other nonmagnetic minerals and gangue using a high-intensity wet magnetic separator (HIWMS). Recently, various versions of this machine made in China have been introduced in wolframite mines. For example, by using the SQC series HIWMS machine to treat the wolframite slime at a plant, a concentrate grade of 8.4% WO3 (concentration ratio of 19.2) with a recovery of 75.96% was obtained. The lower limit of effective recoverable size was found to be 10 m (corresponding to wolframite size 5.3 m) under a condition of maximum field intensity of 1.810 4 Os in the separation zone (Table 3). for cleaning and upgrading, various types of HIWMS are being employed to separate wolframite from cassiterite, apatite, scheelite, etc. for example, in another plant, using the SQC-Z-1100 type HIWMS and a rougher concentrate containing 44.72% WO3 and 1.3% Sn, a final product grade of 55.66% WO3, with 0.19% Sn was obtained at a recovery of 95.47%.

In addition, a new type of high-gradient magnetic separator (HGMS) has been used in tungsten ore processing. Treating a refractory slide which contains 27.55% WO3 53% Sn, and 74% minus 74-m fraction, the machine gave a final concentrate grade of 63.98% WO3 and 0.4% Sn with a recovery of 82.65% WO3.

In recent years, the need has become more and more accute for a high capacity, high intensity, wet magnetic separator for the concentration of finely ground, paramagnetic minerals. As a result of this increased interest, extensive test work has been conducted at our Central Test Laboratory, and the basic design for such a separator has been established.

(a) The magnetic attraction of paramagnetic particles is affected by flux gradient produced within the particle. (b) A magnetic pole, with sharp edges, produces a much higher magnetic gradient than spheres produce. (c) Expanded metal sheets placed vertically, side by side, staggered, and reversed provide a multitude of magnetic flux concentrating edges. (d) Test results indicate that for finer particles the flux converging media should have sharper poles and smaller voids. (e) All three models of the high intensity, wet magnetic separators have the same magnetic flux uniformity and length of magnetic zone (maximum 8 inches). (f) Operational and test work data have shown that the high intensity separator, with the expanded metal sheets, provides a high gradient and is remarkably efficient in the purification of ground and unsized silica sand, wollastonite, talc, clay, cassiterite, and in the concentration of hematite, ilmenite, and semitaconite ores.

In high intensity, magnetic separation, we are concerned with paramagnetic behavior of matter, and this is attained when the magnitude of magnetic moments is sufficiently large to more than compensate for the diamagnetic effect, which is always present. In a solid state sample this orientation process is seriously interfered with by magnetic delay T and temperature vibration.

The laboratory separator is constructed of two electromagnetic coils with a stainless steelbox (8 inches high x 2 inches wide x 1 inch deep) containing the flux converging element between the poles. One valve is located at the entry and the other at the outlet of the element box. A funnel is supplied for the hand, feeding operation.
