Electrostatic Separation Method

 There are two main types of electrostatic separators, they are electrodynamic separators (or high tension rollers) or electrostatic separators. In high tension rollers, particles are charged by a corona discharge. This charges the

particles that subsequently travel on a drum. The conducting particles lose their charge to the drum and are removed from the drum with centripetal acceleration. Electrostatic plate separators work by passing a stream of particles past a charged anode.

These separators are used for particles between 75 and 250 micron and for efficient separation to occur, the particles need to be dry, have a close size distribution and uniform in shape. Of these considerations, one of the most important is the water content of the particles. This is important as a layer of moisture on the particles will render the non-conductors as conductors as the layer of the water is conductive.
Electrostatic plate separators are usually used for streams that have small conductors and coarse non-conductors. The high tension rollers are usually used for streams that have coarse conductors and fine non-conductors.

Magnetic Separation Method

There are two main types of elect Magnetic separation is a process in which magnetically susceptible material is extracted from a mixture using a magnetic force. This separation technique can be useful in mining iron as it is attracted to a magnet. In mines where wolframite was mixed with cassiterite, such as South Crofty and East Pool mine in Cornwall or with bismuth such as at the Shepherd and Murphy mine in Moina, Tasmania, magnetic separation was used to separate the ores.

In this machine the raw ore, after calcination was fed onto a moving belt which passed underneath two pairs of electromagnets under which further belts ran at right angles to the feed belt. The first pair of electromagnets was weakly magnetised and served to draw off any iron ore present. The second pair were strongly magnetised and attracted the wolframite, which is weakly magnetic. These machines were capable of treating 10 tons of ore a day.This process of separating magnetic substances from the non-magnetic substances in a mixture with the help of a magnet is called magnetic separation. This process operates by moving particles in a magnetic field.  

 What machines are used in the Mineral Processing Plant? 

1. Jaw Crusher
Jaw Crusher is ideally suitable for primary crushing, as the most popular stone-crushing equipments, it is widely used in mining, metallurgy, construction material, highway, railway, hydroelectricity and chemical industry for crushing various materials with compression strength less than 330 Mpa.

2. Cone Crusher
Cone Crusher series Composite cone crusher get to world advanced level, absorbing word advanced crushing technology, it is widely used in metallurgical, aggregate, building material industries, it is suitable for crushing varies of hard and above mid hard ores and rock.

3. Vibrating Screen
Yufeng vibrating screen with circular motion is specially designed for quarry to separate crushed stone material into

 different sizes, and is also used as a grading machine in coal dressing ore dressing, construction material electric and chemical industries. It has a feature of advanced structure powerful vibrating forces low vibration noise, easy maintenance high durability, etc.

4. Ball Mill
This machine is a skeleton pattern ball mill with horizontal cylindrical turning gear, drive by outer gear and two hoppers. The

material goes to the first hopper after the spiraling by the quill shaft from the feeding equipment. The hopper has ladder

sheathing or corrugated sheathing with steel balls inside, which will fall under the effect of centrifugal force by barrel turning

to ram hard and grind material. After the kibbling in the first hopper, by monolayer partition panel.

5. Spiral Classifier
We produce high weir type, single and double spiral, and immersed single and double spiral classifiers. Our spiral classifiers are widely used in the separation of ore in closed circuits with ball mills, grading ore and fine slit in gravity mills, grading granularity and flow of metal ore-dressing, and de-sliming and dehydrating in washing.This product features simple structure, reliable working conditions and convenient operation. Because different grains have different specific gravity.

6. Magnetic Separator
The China Magnetic Separators are available in cyclic design with process vessel diameters smaller than 3mm. Magnetic Separator is one kind of efficient equipment for processing fine, feebly magnetic minerals, such as hematite, limonite, wolfram, ilmenite, and tantalum-niobium, etc. In recent years, it is also more and more applied in purifying quartz, feldspar and nephline. Its magnetic system is a ring-shape chain closed magnetic circuit with energizing coils made of copper tube and cooled internally by water. Grooved plates made of magnetic conductive stainless steel are used as magnetic matrix.

7. Flotation separator
 Ore flotation equipments applicable for the separation of nonferrous metal and ferrous metal and nonmetal, such as fluorite and talc. The impeller is driven by V-belts, which can bring the centrifugal effect to form the negative pressure. On the one hand, to inhale sufficient air to mix with ore pulp; on the other hand to stir ore pulp and mix with medication to form the mineralized froth. To adjust the height of flashboard to control the liquid level and make the useful froth scraped by loam board.
