Abstract

The inventive method for producing refractory metals from a concentrate of laporite consists in the following: the concentrate of laporite is finely crushed and disintegrated with the aid of concentrated nitric acid at an atmospheric pressure and a temperature exceeding 100 °C, followed by the production of a pulp of hydrated cake of refractory metal oxide; said pulp is phosphated in order to produce a fluoride solution of tantalum, niobium and titanium; fluotantalate and fluoniobate acids are extracted from the solution with the aid of octyl alcohol and afterwards re-extracted with the aid of water; the remaining fluotitanate acid is evaporated; the tantalum and niobium oxide are extracted from the fluotantalate and fluoniobate acids, and the titanium dioxide is extracted from the fluotitanate acid by means of high-temperature pyrolysis at a temperature ranging from 600 °C to 650 °C. The inventive method is characterized by fluorinating the pulp of the hydrated cake by absorbing a gaseous fluorine hydride from furnace gases with the aid of the pulp. Said furnace gases are obtained as a result of high-temperature pyrolysis of the fluotantalate, fluoniobate and fluotitanate acids. For this purpose, the furnace gases and the pulp of the hydrated cake are counter flowed in the recirculating regime of the pulp.

For the separation of titanium, niobium and tantalum use the precipitation of sulphate of ammonia with small titanium salt (ΝΗ4) Τ4 (30 4 ) • it consumes 70% of the energy supply The dual titanium is used as an effective tanning agent in a low-cost industry. With its thermal decomposition, the titanium dioxide is produced. The remaining after isolation of titanium salt is a solution called a sulfuric acid source that contains tantalum, niobium and a waste of titanium. This product is approved for 40% hydrofluoric acid. After this, there is a filtration of the devices for separating the precipitation of fluids from the activity (torus and mesostrus). Then, to extract the tantalum and niobium, the separation process is carried out by 100% of the RBF process. After the extraction, the process with tantalum and niobium is directed to the final extraction. Уль As a result, this results in the re-treatment of tantalum and niobium in the form of phthostantal and phytobnostic, which is subject to further distinction. For this regenerate, tantalum and niobium process ammonia as a result of which they receive tantalum and niobium hydroxides Τa (0Η) δ and Νι (0Η) 5. Hydroxides promote the thorough washing, drying and drying, as a result of which they obtain the finished product - noxious tantalum and nibb.

Β As a result, it is necessary to share the most valuable components of the less valuable dual Ρ WE with two costs of 25% of the difference in cost. 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 no return loss of tantalum and niobium with crystals of titanium salt and its salting out from the sulfur solution of tantalum, niobium. The use of an agent in the quality of the product makes the process of treating the acids of tantalum and niobium and of them both long and labor-intensive. The separation of titanium from sulphate products in the form of double titanic salt leads to greater losses of titanium due to the significant increase in the level of power.

Other than that, it is a deficient and suitable floating acid, which is used - May 5, for a sulphate-extracting process of tantalum and niobium, in this way it is not utilized, t.κ. Concentration of the concentrate in the plant after extraction makes up only 25-30 g / l, which makes it economically unsuitable to utilize. When implementing the method, there is a greater yield of sulfuric acid, t.κ. Acid from the economy is not removed, but only disposed of in the form of a low-value ammonium sulfate. All this makes it difficult, low-efficient, and economically disadvantageous.

Cooling is ideal with more heat. To reduce the temperature, leaving the heat from the reactive capacitance, there is a water outlet through the coil. After disassembling, the quick-release valve allows the installation and filtration to be removed from the quick-release part of the country, nibia and titanium non-essential part of the country. The natural sediment does not exceed 10% of the original mass of the hydrotherapy. The nozzle is blown away by moisture on the filter. The garden is pulverized by well-known young people, as a result of which - 7 - transfers to a non-replaceable sediment, and discharges to the sludge carrier. The pure physical solution of the tantalum, niobium and titanium directs to the extraction of the tantalum and niobium with a total of 100% organic, known from the same name.

This makes it possible to dispose of up to 98% of the cost of floating acid, which is used in the business cycle. All of this ensures an essential 5th comparison with the sulfuric acid technology, an increase in the efficiency of the system and its economic efficiency.

The cooling system and the cooling equipment must be equipped with a high speed due to an excess of speed. This substantially complicates and equips the equipment, the use of the hydraulics sump, and the exchange of hydrous acid. At the same time, the process of the process of distribution is organized in the process for securing the transfer of non-removable goods to the environment. The resulting filter after the pulp has been received is filtered and has a filtering rate of only 0.07 to 0.113 m 3 / m 2 hour. Due to the high concentration of fluorine, it is also a fluent agent, the resulting phantom compounds of tantalum, niobium and titanium are contaminated with impurities (iron, rubble, etc.). The use of floating acid results in a reduction of 1.6% of the resulting valuable process components, which results in a resultant loss of the product.

The distinguished flow of water from the hydraulically operated fuel cell does not require a solution, τ. κ. It will be used for evaporation of water, t. e. at an interest in production facilities - 1 1 - to valuable components (Τа, ΝЬ, Τ ϊ). When the hydraulics of the gas-fired gas generator are disposed of in the factory, the valuable components are disposed of in the first place. The resulting products and the pureer products are available for the next product, which will result in a more complete finished product. Concentration of gas is produced by a large amount of hydrogen in typical gas gases, which creates gentle conditions for the treatment of plants. There is no increase in gas costs when the gas is in the form of a vented gas; The investigation of all of this and achieved an improvement in the system, an increase in its efficiency and economic efficiency.
