There are four essencial methods in ore dressing plant, including gravity separation, flotation separation, magnetic separation and electrical separation. The following text will elaborate on these four methods.

1. Gravity Separation

It is an industrial method of separating minerals by the difference of their relative density. Mineral particles of different density receive the hydrodynamic and various mechanical force in the moving medium like water, air and heavy liquid, causing proper loose strata and separation conditions, by which minerals of different density are separated.

2. Flotation Separation

According to the physical and chemical differences among minerals, they can cling on air bubbles selectively through flotation reagent’s disposal. The ore dressing of nonferrous metal like copper, lead, zinc, sulphur, molybdenum, etc. usually adopts this method. Being part of flotation plant, flotation concentrator is the latest design to use the circular tank concept, and combines the benefits of circular cells with the unique features of the minerals mechanism to create the ideal conditions to maximize floatation performance for all roughing, cleaning and scavenging duties.

The machine can be used to separate nonferrous metal, ferrous metal, noble metal, nonmetallic mine, chemical material and recycle mine. It features high inhalation and low power. Each chute can inhale gas, sink magma and separate – there is no need for accessory equipments. It is easy to change the flow chart. The cycling way of magma is very reasonable and it can reduce the impurities to a great extent. There is automatic equipment on the magma surface. The machine is easy to adjust; the upward one makes the magma cycle upward and the downward one makes the magma cycle downward.

3. Magnetic Separation

This method is based on the different mineral’s magnetic property. They are separated by the different acting force in the magnetic field of magnetic separator. It is mainly used in the separation of ferrous metal like iron, manganese, chromium, etc. It also can be adopted in the separation of nonferrous metal and rare mental. stone jaw crusher:http://www.crusher-machine.com/1.html

Magnetic Separators are machines that are primarily used to eliminate tramp iron from ores and for removing contaminating materials that can damage equipment. They can separate the minerals dependent on the different magnetic factor, magnetic force and mechanical force. These separators can be divided into different kinds, such as Suspension Magnets, Plate Magnets, Hump Magnets, Magnetic Drum Separators, Magnetic Pulleys and Magnetic Grids. This separator magnetic is a new mine selection machine which is developed in the recent 20 years, mainly used in thin grade ferromagnetism mineral dry and wet separating. They have good features such as high capacity, good quality, easy to be repaired, easy to be transported.

4. Electrical Separation

Minerals are separated by the difference of mineral’s conductivity. When minerals are in the high-voltage electric field of electricslot, due to the different conductivity, minerals are separated by the different acting electrostatic force. At present, it is mainly used in the separation of mixed crude concentrate like the separation of scheelite and cassiterite, the concentration of zircon and tantalum-niobium ores, etc.
