Titanium beneficiation process of ilmenite

Generally, wet weak magnetic separation is used to select titanium magnetite first, and then fatty acid collectors are used to float calcite. After the middlings are de-doped, ilmenite is floated.

The beneficiation process of ilmenite depends on the nature of the material. Since the specific gravity of titanium minerals is relatively large compared to non-metallic gangue minerals, gravity separation can be used for pretreatment or rough separation and tailing; magnetic separation is widely used in iron removal operations to improve the concentrate grade of ilmenite, and can also be used to enrich ilmenite with a smaller specific gravity of gangue minerals; electrostatic separation is mostly used for purification operations when various non-conductive minerals are contained in titanium concentrate selected by other processes; flotation is more suitable for the beneficiation of primary ilmenite fine-grained ore.

Placer-type ilmenite, especially sea sand-type ilmenite weathered from pegmatite, can select titanium concentrate with a grade of more than 50%. Titanium selection process | The specific process of titanium selection from ilmenite is as follows: after the raw ore is cracked and screened, it can be roughly selected, scavenged and finely selected by jigging, spiral, chute, shaking table, cone concentrator, etc. according to the particle size characteristics of useful minerals in the sand ore. When the raw ore contains a lot of mud, it must be washed and desludged first. Desludging generally uses a hydrocyclone. For the selection of titanium-containing coarse concentrates, magnetic separation, electrostatic separation, gravity separation and flotation methods are generally used, and they are staggered according to the different properties of the minerals. The mixed concentrate uses electrostatic separation, magnetic separation and gravity separation to select four types of concentrates such as ilmenite, rutile, zircon and monazite.

The difference between quartz and mica

Mica and quartz are common minerals that play an important role in mineralogy. Although they are both silicate minerals, there are clear differences between them. First, mica and quartz are very different in appearance. One of its distinguishing features is that mica exhibits a layered structure that can be easily peeled off into thin flakes. Quartz, on the other hand, is a uniform crystal with no layered structure. Additionally, mica is usually dark in color, such as black, brown, or green, while quartz is usually clear or white. Secondly, mica and quartz also differ in their physical and chemical properties. The hardness of mica is usually between 2.5 and 4, which is relatively easy to be scratched; while the hardness of quartz is very high, 7, which is a very hard mineral. In addition, mica has good refractive properties and electrical properties, while quartz is an excellent piezoelectric material.

Slove method of the clogging of trommel screen sieve

The drum screen is a simple screening device. The trommel screen is easy to close and collect dust, the maintenance is small, the maintenance is simple, and the service life is long. It is a device frequently used in refractory materials, coal, river sand classification, and sandstone classification. The advantage of the trommel screen is that the structure is not complicated so that the device can be quickly operated, and when the trommel has problems, people can easily solve it. But what should I do when the screen of the trommel screen is blocked? The following screen will introduce several ways to solve the phenomenon of blocking the net. The trommel screen sometimes adopts a mechanism added to the fixed frame, and then the mechanism rotates to drive the belt mounted on the belt to continuously smear the surface of the sieve hole, thereby sucking out the raw material particles blocked in the sieve hole. One of the disadvantages in practice is that it produces a lot ...

The classifications of quartz sand

1. Ordinary quartz sand: The surface of ordinary quartz sand seems to have a layer of yellow skin, and some have large particles and strong fire resistance. It is a kind of quartz sand processed by the manufacturer after using natural quartz ore in the production process, such as washing and drying. No impurities can be seen in the quartz sand through the second water treatment filtration. It is the best choice for chemical water treatment. It can block the sundries suspended in the water and maintain the quality and beauty of the water. 2. Refined quartz sand: Refined quartz sand is a mineral made by the manufacturer after carefully selected quartz stone. According to different requirements of users, the range used is also different. But generally the main use of refined quartz sand is in glass products, because refined quartz sand is refractory and precision casting, especially suitable for fireproof glass materials.
