With the rapid development of the era of artificial intelligence and the interconnection of all things, the new era of intelligent mine is really coming. With the rapid pace of 5g technology commercial, a large number of related applications are also ready to come out, 5g technology is also applied to unmanned mining equipment, and graally become a reality
The age of5g is coming, although the intelligence is very good, the artificial can not be completely replaced
The cost of setting up 5g base station is also very high, because 5g base station itself is not connected by wireless, it is still connected with the operator's server through optical fiber. So where the 5g base station is built, the optical network will be laid. Some cities are lucky to say that a backbone optical fiber can provide network services for hundreds of thousands or even millions of people. But in remote mines, the cost of laying a fiber-optic network is relatively high. In particular, some mines are not only remote, but also have dangerous terrain, and some even have no roads, which brings great difficulties to the erection of 5g base stationstherefore, if we want to use 5g for mining, the initial investment cost is very high, and not all units can afford it. Of course, there is also a technical solution is to establish 5g LAN, 5g is only used for short-distance communication, and does not need to connect to the external network. Of course, this requires remote control personnel to be close to the mining site. Although there are some restrictions, it is safer than traditional mining methods
in general, the technology of mining with 5g remote control is still at the level of publicity, which is far away from the actual application. Of course, if 5g network is spread all over the country in the future, 5g can be used everywhere to access the Internet, and the cost of use is also reced, then the technology of remote control of construction machinery will certainly be more practical
2. The first generation extraction process of ionic rare earth can be described as & quot; Extraction technology in different places;, Or it comes down to & quot; Pool leaching process & quot;. The main technological process is as follows: topsoil stripping → excavation of ore bearing body, ore transportation → leaching pool → taking electrolyte solution prepared according to a certain proportion (concentration requirement) as & quot; Eluent & quot; Or & quot; Leaching agent;, The solution is added to the leaching tank, and the concentration of & quot; Ionic phase & quot; Rare earth ore is analyzed by & quot; Percolation elution & quot; Or & quot; Leaching & quot; In the solution, the active ions exchange with rare earth ions; Ionic phase & quot; Rare earth is exchanged from the ore bearing carrier minerals and becomes a new state of rare earth; Add & quot; Top water;, The mother liquor containing rare earth was obtained; The mother liquor flows into the collecting tank or mother liquor tank through the pipeline or infusion ditch, and then enters the sedimentation tank; After leaching, the waste resie is removed from the leaching tank and discharged in different places → precipitant and impurity remover are added to the sedimentation tank to remove and precipitate the rare earth from the mother liquor and obtain mixed rare earth; After treatment, the supernatant was returned to the leaching tank for & quot; Eluent & quot; The purity of mixed rare earth oxide is more than 92%. It can be seen from the above that the key words in this process are: & quot; Topsoil stripping& quot; Excavation of ore bearing body& quot; Ore handling& quot; Leaching pool& quot; Eluent & quot& quot; Allopatric percolation elution& quot; Ion exchange& quot; Rare earth containing mother liquor& quot; Tailing discharge in different places& quot; Mother liquor pool& quot; Sedimentation tank& quot; Precipitant, impurity remover& quot; Precipitation and impurity removal& quot; Mixed rare earth& quot; Supernatant return& quot; Burn & quot& quot; REO ≥ 92% mixed rare earth oxides< br />
" Pool Leaching Technology & quot; Compared with the traditional proction process, the first, second and third processes are similar to those of the traditional mining process; The third, fourth and fifth working proceres are similar to those of traditional mineral processing and hydrometallurgy; The processes after the fifth process belong to the traditional hydrometallurgical processes. Among them, the & quot; Leaching pool;, It plays the role of connecting traditional mining and mineral processing professional operations, similar to the & quot; Raw ore & quot;; The & quot; Sedimentation tank;, However, it plays a role of connecting traditional mineral processing and hydrometallurgy, similar to the & quot; The raw material is & quot
therefore, similar to the main separation process of traditional mineral processing specialty, it is in & quot; Leaching pool & quot; And as an intermediate proct of the process, a mother liquor containing rare earth is obtained here; The typical hydrometallurgical process, which belongs to the traditional hydrometallurgical specialty, is mainly in & quot; Sedimentation tank & quot; And from this we get & quot; Rare earth concentrate & quot; The primary procts of China; Mixed rare earth & quot;; The & quot; Rare earth concentrate & quot; Final proct: mixed rare earth oxide with REO ≥ 92%
in addition, in the above operation process, we obtained & quot; Intermediate procts& quot; Primary procts & quot; And & quot; Final proct & quot;. That is, in & quot; Leaching pool & quot; The mother liquor containing rare earth was prepared by ion exchange; In & quot; Sedimentation tank & quot; The mixed rare earth was prepared by precipitation; In & quot; Burn & quot; The mixed rare earth oxide was prepared by the reaction of rare earth and rare earth. Therefore, in order to ensure the proct quality of ionic rare earth, we should control the technology in the three key operations
in this process, the & quot; Rare earth concentrate & quot; Proct is no longer the traditional concept of & quot; Rare earth concentrate & quot; Mineral procts, but relatively high purity & quot; Mixed rare earth oxides & quot; Procts. Strictly speaking, the final procts obtained from ion type rare earth mines are no longer subordinate to & quot; Mineral procts;, It is a proct in the field of hydrometallurgy. Obviously, the grade of its procts has been greatly improved compared with that of traditional mining procts
the above process structure is a new process in the development and utilization of rare earth mineral resources. It completely breaks the traditional process of rare earth resource development, and integrates a variety of specialties and processes to directly proce high purity mixed rare earth oxide procts in mines. Using this proction process, the quality index of the proct is difficult to achieve in the previous rare earth proction process. It can be seen that using this proct as raw material is very beneficial to the further processing of rare earth smelting
however, everything in the world often has & quot; Duality & quot;. Ionic rare earth has a very outstanding advantage, but because of its occurrence characteristics and process characteristics, it is not satisfactory on the other side. With & quot; Pool Leaching Technology & quot; After instrial proction, there are some very sharp and prominent problems: first, the ecological environment is greatly damaged. Due to the widespread occurrence of ionic rare earth in the shallow layer of the earth's surface, the distribution area is large; Pool Leaching Technology & quot; In fact, the proction process is a & quot; The movement of moving mountains;. According to statistics, for each ton of mixed rare earth oxide proction, about 1201-2001 tons of ore will be consumed. At the same time, 1200-2000 tons of tailings will be proced, and the sanding area is about 1 mu. Second, the utilization rate of resources is low and the waste of resources is large. In order to facilitate the mining and transportation of ore and the discharge of tailings, rece costs and save investment, the & quot; Leaching pool & quot; It is located in the middle and lower part of the hillside orebody; Leaching pool & quot; The following ore bodies are controlled by the established proction system; Ore pressing;, Especially if it is covered by tailings, it is more difficult to exploit. According to the data, the utilization rate of resources in the process table is generally less than 50%, and the lower is only about 25-30%.

4. Luoyang motun airport nearby to buy a house, but there is potential to send football, and there is a lot of room for appreciation, because the house in the airport, the house price will be higher and higher.
5. The environment there is OK. It's better to be close to the coastal areas now
6. Just so so? You don't see that there are all low tech and ragged machinery companies. In the urban area, they are not easy to obtain the qualification to build factories, and the entry threshold of Mahui is very low. As long as the tax can be increased, I will allow you to enter. Therefore, it has attracted many companies. It can be said that Matun is now a gathering area for ragged companies. If you're a high-tech company, don't go there. They're very informal. Many companies often delay paying wages
Add: take bus 83 to have a look. Most of that area was relocated from the urban area e to heavy pollution. Although there are many companies, the infrastructure is very poor, and there are glass fiber companies. If you ask the workers, they all know that layoffs in off-season and recruitment in peak season are the common tactics of many companies in that area. Especially in machinery factories, many of the wages are paid by the workshop team leaders on their behalf, and then they dect some wages and give them to the employees
Add: Although the company is not very good, the house price will rise in the future. In about 10-15 years, it will certainly become a new area, including Changbao Township and Chaoyang Township, which will be connected to Geely district. If you are satisfied, please accept my answer. thank you.
