The beneficiation technique of kyanite , andalusite and sillimanite is an island-like silicate mineral. The composition is Al2[SIO4]O. It is similar to the andalusite and the scorpion line. The triclinic system has a flat slab shape. Sometimes it is a radial aggregate. Blue, white with blue, cyan. There are two sets of complete and medium cleavage. The hardness has obvious anisotropy, so it is also known as the hard stone. The Mohs hardness was 4.5 in the direction of the parallel crystal elongation and 6 in the vertical direction. The specific gravity is 3.53 to 3.65. A product of regional metamorphism, occurring in crystalline schist and gneiss . Switzerland and Austria are well-known places of origin. When heated to 1300 ° C, the kyanite becomes mullite and is a high-grade refractory material. Aluminum can also be extracted. The transparent crystal can be used as a gemstone , preferably in dark blue.

The movable joint is also called "Ren" or "Ren". It is a common pipe connector that can be easily installed and dismantled. It consists of three parts: nut, cloud head and flat connection. The varieties of bearing joint are equal diameter and different diameter.
It mainly consists of three parts: nut, cloud head and flat connection. A pipe connector that is machined by forging a round steel or ingot, which is connected in the form of socket welding and threaded connection. The socket welding is welded by inserting the Steel Pipe into the socket. Therefore, it is called the "socket joint". The threaded connection is the connection of the steel pipe into the screw hole. Therefore, it is called "screw work". The main manufacturing standard is ASME B16.11 and MSS SP 83.
The varieties of bearing joint are equal diameter and different diameter.
Threaded joints are threaded connections, which are the most common fittings in industry and life. The threaded joint makes the connection of the pipe simpler, and the disassembly and replacement is easier, which greatly saves the cost of the pipe connection.

The ore of kyanite, andalusite and sillimanite has only a few high-grade ore-rich ores, most of which are composed of kyanite minerals and gangue minerals; and contain iron minerals, titanium- containing minerals, graphite , and carbonaceous materials. Etc., ore grade is low, kyanite is usually 10% to 25%, andalusite is 10% to 25%, and sillimanite is 10% to 60%. Therefore, it cannot be used directly. It must be subjected to beneficiation and purification to remove impurity minerals. It can be used as a refractory raw material by enriching useful minerals into concentrates. The kyanite raw materials currently on the market are concentrates after beneficiation.
The beneficiation method and process flow are determined according to the characteristics of the deposit, ore grade, structural structure, ore size embedding, inclusion body and surrounding rock. For fine-grained kyanite minerals, the density of ore differs from that of gangue minerals, mainly by flotation; mixed ore, including coarse and fine inlays Ores, in addition to the re-election-flotation combination method; grading flotation method can also be used; for coarse-grained inlays, fine-grained ore-like ores are mostly treated by re-election. Magnetic separation is often an indispensable process in the mineral processing of kyanite family. First, it is used for the preparation of raw materials, recycling and removal of magnetic minerals. Second, it is used for reprocessing of concentrates to eliminate harmful impurities in concentrates. . Fine-grained kyanite beneficiation, foreign acid flotation is mostly used, and the iron-containing minerals in flotation concentrate are separated by magnetic separation; China's flotation fine-grained kyanite is mostly reduced by flotation. For the coarse crystal of andalusite, the re-election method-magnetic separation process is generally adopted, and the fine-grained andalusite is recovered by flotation. Flotation method is used in foreign countries to obtain sillimanite concentrate. Flotation is mainly to solve the separation of gangue minerals such as sillimanite and quartz , feldspar, etc. In order to meet some requirements for lower impurity content of sillimanite, sometimes The flotation of the sillimanite concentrate is then subjected to pickling treatment.
It is composed of socket, socket, socket, socket, socket, socket, socket and socket on both ends of the socket. Compared with the existing technology, the design is reasonable, simple and practical, and the operation quality and convenience are improved.
Socket joints can be widely used in pipes with different diameters, and can also be used for water meters and valves. Because of the adoption of the socket structure, the pipe joint is very convenient to reduce the cost, installation, use and maintenance, at the same time, it also has high leakage resistance, and has a very good market prospect.
Industrial threaded joint is usually made of metal, with high pressure resistance, carbon steel, stainless steel, alloy steel, brass and so on. The living threaded joint materials are generally PC, PVC, PE and so on.
Threaded joint, which is a pipe connecting piece with thread, is the most common type of pipe in industry and life. The threaded joint makes the connection of the pipe easier, and it is easier to disassemble and replace, greatly saving the cost of the pipe connection.
