1. 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%.

2. Hello, 5g mobile phone needs to open the corresponding 5g package to use 5g network. It is recommended that the perfect 5g integration package, mobile phone package + broadband combination, as low as 129 yuan, enjoy 300m broadband, 15g domestic traffic and 500 minutes of domestic calls. One main card can also be superimposed with two secondary cards to share traffic and package.
3. When I buy a mobile phone card, I basically put it aside and ignore it. It's useless to have so many mobile phone numbers. The local business hall can choose a set meal suitable for itself, and all three operators can choose it. If there is a problem, I can deal with it in time. Why bother to do it online? It's really troublesome.
4. At present, there are two kinds of options in China: on the market and off the market
there is only one stock exchange company in Shanghai Stock Exchange 50ETF. This indivial is able to do it, but has higher requirements. It requires a capital of more than 500000 yuan, market simulation trading, and participation in examinations. It takes a long time, about a few months, to open an account
out of the market is indivial stock option. Originally, options could be short. At present, securities companies only put call options, and they are American options
according to the way of exercise, options are divided into European style and American style. European options can only mature, while American options can exercise at any time ring the term. That is to say, the European option can only be exercised after one month, while the American option can be exercised at any time within one month<
at present, over-the-counter stock options are very popular. One million shares need less than 100000 royalties. If the stock rises by 30% in a month, then the indivial's profit is 1 million × 30% is equal to 300000. After decting the royalty, the profit is 225000, with a profit margin of 200%. If the share price falls, even if it falls by 50%, the indivial will only lose 75000 yuan in royalties. Real high leverage, high return, controllable risk
I'm in the business now. I'm just starting and very popular, because it suits the taste of Chinese shareholders. If you don't understand, or want to be a small partner, or want to be a shareholder friend of this proct, you can have a private chat and consultation.
