what is magnetic separation method for concentration of ore？

Magnetic sorting equipment type:

One, Weak magnetic field 1. Magnetic roller (magnetic pulley) The magnetic roller has two kinds of permanent magnet and electromagnetic. It is mainly used for ferrous metal mines to discard a large amount of waste rock before ore selection, thereby improving the original ore grade, increasing the processing capacity and saving energy. Due to its simple structure, reliable operation and energy saving, the permanent magnet magnetic cylinder has been widely used and has been listed as a ministerial standard. Its model number is from CT-66 to CT-816, that is, the cylinder size DXL=630×600 to 800×1600. The magnetic roller has a tendency to develop toward large size and high field strength. In order to increase the field strength of the permanent magnet roller, the magnetic pole material is changed from the ferrite to the yttrium copper permanent magnet alloy, and the magnetic pole gap is changed from the original unfilled material to the boring copper alloy. At present, China's magnetic drums and magnetic ores are selected by means of sorption. When the ore layer is thicker, the magnetic ore in the upper part is easy to enter the tailings due to the small magnetic force, which makes the grade higher. The electromagnetic system is above the sorting point and is mainly used for selecting magnetic materials. The permanent magnet system is arranged side by side with the electromagnetic system. It is mainly used to keep the magnetic material on the surface of the cylinder and is transported to the weak magnetic field area as the cylinder rotates. 2, dry selection type weak magnetic field magnetic separator dry selection type weak magnetic field magnetic separator is mostly permanent magnet magnetic system, mainly used for dry selection of fine-grained strong magnetic ore, also used to remove magnetic properties from powdery materials Impurities and purification of magnetic materials. It has been widely used in metallurgy, chemical, cement, grain and other sectors as well as in the treatment of soot, slag and other materials. 3, wet selection weak magnetic field magnetic separator due to the development and application of permanent magnets, the wet selection of weak magnetic field magnetic separator is increasingly consistent. It is generally believed that the drum type is superior to the belt type. The permanent magnet is superior to the electromagnetic. At present, the Chinese permanent magnet type weak magnetic field magnetic separator almost monopolizes the wet magnetic separation field of ferromagnetic minerals. The permanent magnetization of the equipment has been realized, and the serialization has been developed to a large scale. The permanent magnet type weak magnetic field magnetic separator has three types according to the tank structure, namely, a semi-reverse flow type (CTB type), a counter current type (CTN), and a downstream flow type (CTS). The most commonly used is the semi-reverse flow type. For example, the permanent magnetic cylinder magnetic separator of Yantai Xinhai Mining Machine has high degree of automation, good selection index and wide application range, and is widely used. CTB type is suitable for rough selection and selection of 0.5~0mm strong magnetic ore, especially suitable for the selection of 0.15~0mm strong magnetic ore. CTN type is suitable for rough selection and sweeping of 0.6~0mm strong magnetic ore, and coal preparation. The recovery of heavy medium in the process, CTS type is suitable for rough selection and selection of 6~0mm strong magnetic ore. 4. The magnetic desilting tank is mainly used in the permanent magnet system, which is installed at the top and bottom, respectively called the top magnetic system magnetic desilting tank and the bottom magnetic system magnetic desilting tank. The former series of specifications mainly include CS-12s, CS-16s, CS-20s, ie the slot diameters are 1200, 1600 and 2000.

Second, strong magnetic field 1, dry selection strong magnetic field magnetic separator in China using the early dry selection strong magnetic field magnetic separator electric disk type strong magnetic field magnetic separator, permanent magnet pair magnetic field magnetic separator and flat magnetic separator . Used for the selection of black tungsten ore, iron ore, iron ore and other rare metal ores. These two magnetic separators have been basically finalized. Disc magnetic separators are used in a wide range of applications. In the past ten years or so, the ore processing of ferrous metal ore such as manganese ore has been carried out. The relevant units have developed various types of induction roller type strong magnetic field magnetic separators for processing coarse and medium-grain weak magnetic ores. 2, wet selection strong magnetic field magnetic separator dry selection strong magnetic separator machine is suitable for processing coarse particles, the selected particle size upper limit can reach 30 to 50mm, the product does not need to dehydrate, simplify the production process, but its shortcoming is only suitable For the selection of dry and best graded ore; ore-sized, moist or mud-containing ore, the sorting effect is not good. In order to overcome the shortcomings of the dry-selective magnetic separator, it can handle coarse-grained ore with a wide range of grain size, and fine-grained ore with narrow particle size range. According to this requirement, a wide variety of wet selection occurs at home and abroad. Magnetic field magnetic separators, but the basic types can be divided into two categories, namely roller and ring. 3. High-gradient magnetic separator The wet magnetic field magnetic separator is not good for sorting materials smaller than 20μm. Because the high-gradient magnetic separator can generate strong magnetic force, it can be effectively recovered for materials smaller than 20μm. Micron-sized materials can be sorted. 4, SLON type pulsating high gradient magnetic separator general high gradient magnetic separator has magnetic medium mechanical inclusion problems, in order to overcome this shortcoming, developed into a pulsating high gradient magnetic separator. A vertical ring is arranged, and a device for generating a pulsating water flow is arranged at the lower part of the ring, and the ore particles in the sorting zone are subjected to the action of the pulsating water flow to eliminate mechanical inclusions.
