Abstract

The inventive method consists in grinding and breaking down a loparite concentrate by nitric acid. A solution is separated by the filtration thereof on a ferrum-thorium cake and a pure nitrate solution of rare-earth elements which are precipitated by sodium carbonate in the form of a totality of rare-earth element carbonates. A filtrate is processed by evaporation until a concentration of 500-600 g/l is obtained and by subsequent hydrolysis at a temperature of 600-800 °C, thereby producing elementary nitrogen, oxygen and carbon dioxide in exit gases and powdered sodium oxide. The sodium carbonate produced by the interaction of said sodium oxide with carbon dioxide is provided in order to neutralise a nitrate solution and precipitate the rare-earth element carbonates. The exit gases are exposed to water washing and released into the atmosphere.

The original concentrate of the pulp mill is crushed to a size of at least 0.075 mm and is classified. The deduction of a percentage of 0% is made with a total of 95% of sulfuric acid, which is calculated from a calculation of 2.78 tons per 1 tons of crushed percentage. In order to prevent sintering of the reacting mass and to increase the extraction of niobium and tantalum in the solution. To the sulfuric acid they add ammonium sulfate (0.2 t per 1 t of concentrate). Ρ ρ-5, due to the increase in temperature, which is 270–280 ° C, it is more and more likely to be a large part of the country. The earth elements are part of the dual SZE - 2 (80 4 ) s • (Η) g δ0. Sulfatization Product 0 — The sulphate feeds directly through leaching. Уль As a result of this, in solid phase, two SZE sulfates remain, and in the liquid phase titanium, niobium and tantalum sulfate remain. In this case, the activity caused by the presence in the case of the source of radiation alpha 5 of the oxygen source, is divided between solid and liquid phases of 50. For the separation of titanium, niobium and tantalum are used, the precipitation of sulphate of ammonia is an irreplaceable titanium salt (ΝΗ 4 ) ΤϊΟ (δ0 4 ) y Η is consumed 70. The double sulphate of titanium is used-0 zuyut as an effective tanning agent in a tinny industry. With its thermal decomposition, the titanium dioxide is produced. Continued after the isolation of titanium salt, a solution called an sulfuric acid source, contains tantalum and niobium. This is an expansion that contributes 40% ΗΡ. Then, for extraction of tantalum and niobium, there is a process of separation - - 3 - continuous extraction of 100% of the waste water. In order to ensure the possibility of the subsequent extraction of agricultural metals, there is an additional independent self-propulsion cycle of the vehicle.

Β As a result, it is necessary to separate the most valuable components of the less valuable dual SZE sulphates, with different costs of 25-30%. For the restoration of the tantalum and niobium, there is a need to carry out an additional processing of the rest of the cake, which remains after the restoration of the drives. Otherwise, there are non-returning processes of tantalum and niobium with crystals of titanium salt and its salting out from 0 sulphate of tantalum, niobium. Otherwise, this is a multi-part system consisting of separate, portable components that are not compatible with one another. All of this makes it easy and convenient. 5 All these shortcomings are installed in the process of processing the patient center of the Russian Federation Patent 2145980 on July 27, 1999 7 С22Β59 / 00, which was developed by the applicant and is the claimed invention.

With this temperature range and atmospheric pressure, it is exactly the same as in the case of pressure. In general, 0% is obtained after exposure to nitric acid of all parts of the patient's concentrate. At the same time, the temperature was at a maximum temperature close to that of the nitrogen mixture of nitric acid and the temperature of 122 ° С in the boiler. Keeping it at a temperature below 115 ° C results in a complete loss of particles of the patient, and maintaining a temperature of over 118 ° C is not an inconvenience to To increase the residence time of the particles of the drug in nitric acid and to increase the probability of their destruction, the by-product is available in a so-called cascade variant. For this, the large volume is divided into a number of small volumes and consequently connect them.

At the same time, in the process of ingestion due to the impact of nitric acid in the process, the solution was converted to non-corrosive products and all other expenses are excluded. The most valuable of the distinguished combs are 5 components of the disease - oxides of tantalum, niobium and titanium - 9 - Totally not discharged with nitric acid and completely absent, 100 remains in the solid part, being converted to hydrated ones In this case, in K-5, these components are in the mixture, similarly, because they were in the patient compartment.

With this, the hydrotherapy is practically non-existent, because it is active. ~ 95% of the oxide is in nitrogen, which is a result of the loss of ZE and impurities and, therefore, does not undergo further processing.

Flushing is carried out in the sale of pulp and wastewater. Β As a result of washing, a clean hydrated cake is obtained in the form of a pulp with a concentration of nitrates of ~ 2 g / l and a concentration of solid of Stv = 150-200 g / l. The Pure Hydraulic Compound is the original 5 product for the subsequent production of negative oxides from refractory metals, which are expressly acknowledged to be free of charge. The process of obtaining oxides of tantalum and niobium from the hydroprocessor is privately owned and, therefore, is not addressed here. If it is cleaned, after washing it receives a combined nitric acid solution with all impurities (it, Ca, δ, e, δ Ra 228 ). Then decontaminate the nitric acid solution of the OZE, which does not consume labor. For the 5th, first in the factory, they dispense the products of the house - 10 - neutralization of nitric acid. Then it delivers the result of the step Q4, so as not to add the extra katon and the barium does not need to be lost, because the result is the result of a by-product. Factory 5 has reactive chemicals with rhodium, which is present in one chemical group with barium, and, therefore, is in danger of reacting, Β As a result, this sulphate of radium δаδ0 4 is introduced into the crystalline lattice of sulphate of barium δаδ0 4 0 and drops out together with it in the bush. The neutralization of the process results in that, as a result of the process, which is sold in the form of a waste, it is disposed of in an irreplaceable plant.

Due to the impact of 0 sulphate bytreatment, partial binding of calcium and strontium to minor sulphates of Caδθ4 δδδθ4 occurred, which also occurs in the garden. The process of neutralization and decontamination is ideal at a temperature of £ = 70-80 ° C and ρΗ = 4.5–5.0 for 6–8 hours. 5 The next filtration from the product removes the iron-thorium cake, which contains all activity, all iron, partial calcium and constituents.

Resulting in the result of 0 filtering, the clean, non-active, non-hazardous waste of the WZE is the original product for extracting from the earth-based earth elements.

The concentrate evaporates to a concentration of 500-600 0 g / l, and then the hydrate is hydrated at a temperature of £ 600-800 ° С. The hydroprocessing is carried out in the well-known tower quick-printing presses operating on a mixture of p-propane and butane or natural gas. The hydrated solution concentrates the spray of dust and spray 5 spray nozzles in the upper part of the furnace. In the process of hydrolysis, there is a thermal decomposition of nitrates with the formation of elemental nitrogen and oxygen, as well as of oxidized gas. The processed salt and, therefore, calcined soda in the form of a vegetable mixture in the form of a 0 waste powder are dispensed in the oven. Flammable gases are supplied to the scrubbers for quick and efficient use of dust and traces of nitrogen. As a result of the contact with the exhaust gas, the exhaust gases are completely cleaned and then discharged into the atmosphere. Hydraulic products obtained by water are sent to neutralization of excess nitric acid, indicated above 5, and to deposition of fertilizers for ground-based elements.
