Description

Technical Field

[0001] The invention relates to the technical field of material production systems, and in particular to a production system for extracting germanium by oxygen pressure leaching of germanium-containing materials. Background Art

[0002] The extracted germanium is widely used in fiber optic communications, solar cells, chemical catalysts, infrared optics, aerospace, and other fields. With the continuous development of these fields, the demand for germanium is also increasing. After pretreatment (such as crushing and grinding), the germanium-containing material enters the oxygen pressure leaching stage. Under high pressure and oxygen, the material comes into contact with an aqueous solution or other liquid, and the germanium is converted into the liquid phase through a chemical reaction. Subsequently, the germanium is separated from the liquid phase through precipitation, extraction, ion exchange, and other methods, and further enriched and purified. Finally, the waste liquid is recovered.

[0003] The application document with publication number CN104046801A discloses a method for extracting germanium from germanium-silicon raw materials. The raw materials are tested and analyzed according to traditional mineral component content detection methods. When the germanium-silicon raw materials contain ≥2% silicon, the raw materials are divided into compound raw materials and alloy raw materials. The compound raw materials are leached using a two-stage leaching method, and the alloy raw materials are leached using a three-stage leaching method. Each leaching stage uses a leaching material prepared by combining at least two of fluoride, oxide and acid. The ratio of leaching material to raw material is 3-5, and the temperature is adjusted to 80-90°C for 3-4 hours. The leaching residue is then placed in the next stage of leaching material, and the previous stage leaching method is repeated. The solution is then separated and extracted using traditional separation and extraction methods, and ≥76% of silicon and ≥90% of germanium in the germanium-silicon raw materials can be leached.

[0004] In the prior art, waste liquid recovery mainly relies on manual operation, which reduces production efficiency. Summary of the Invention

[0128] The relationship diagram of the measured humidity of the reference environment and the environmental humidity index, where the dotted line represents the ideal value of the environmental humidity during spectral detection. The relationship diagram shows that the value of the environmental humidity index will only increase when the measured humidity of the environment exceeds the ideal value of the environmental humidity during spectral detection, which is used to reflect the potential impact of high humidity on the amount of precipitant input.

[0129] Specifically, the unit of the precipitant input is grams; the unit of the waste liquid volume is liters; the reaction molar ratio is determined according to the chemical reaction equation. For example, taking the precipitation of lead ions as an example, sodium hydroxide is used as the precipitant, and the reaction equation is as follows: From the reaction equation, we can see that 1 mole of 2 moles are required , that is, the corresponding reaction molar ratio is 2; the unit of the molar mass of the precipitant is gram per mole.

[0130] The unit of the measured concentration of heavy metals is milligrams per liter; the unit of the measured ambient temperature is degrees Celsius; the unit of the ideal value of the ambient temperature during spectroscopy detection is degrees Celsius. The ideal value of the ambient temperature during spectroscopy detection refers to the appropriate ambient temperature suitable for the spectrometer to work, which can usually be queried in the relevant parameters set at the factory.

[0131] When calculating the concentration index of heavy metals, two influencing factors, temperature and humidity, are introduced. This is mainly because when the measured temperature of the environment is too high, the components inside the spectrometer will expand or deform due to heat, thereby affecting the stability of the optical path and the sensitivity of detection, which usually reduces the measured concentration of heavy metals. When the measured temperature of the environment is too low, the components inside the spectrometer will shrink, which will also affect the stability of the optical path and the sensitivity of detection, which usually reduces the measured concentration of heavy metals. When the measured humidity of the environment is too high, the components inside the spectrometer will become damp, affecting its performance, and causing scattering interference, reducing the intensity of the light signal, and thereby reducing the measured concentration of heavy metals. When the measured temperature of the environment is too low, the impact can be ignored.

[0132] The ideal value of ambient humidity during spectroscopy detection refers to the appropriate humidity for the spectrometer to work, which can usually be queried in the relevant parameters set at the factory.

[0133] The first selection threshold of the error index during spectroscopy detection, the second selection threshold of the error index during spectroscopy detection, and the third selection threshold of the error index during spectroscopy detection are set by those skilled in the art.

[0134] The unit of the ideal value of the ambient temperature corresponding to the formation of precipitation during spectroscopic detection is degrees Celsius. When the measured temperature of the environment is too high or too low, it will lead to poor morphology of the precipitation or reduced purity, and a corresponding amount of precipitant needs to be added; the unit of the ideal value of the stirring speed and the set value of the stirring speed is revolutions per minute. The ideal value of the stirring speed is set by a technician in this field through table query. It is based on the evaluation of the corresponding waste liquid volume under an ideal stirring environment to obtain a specific value. However, due to environmental changes during stirring and the influence of stirring volatility, technicians in this field will adjust some parameters before stirring, thereby obtaining the corresponding setting value of the stirring speed; the unit of the ideal value of the stirring time and the setting value of the stirring time is minutes. The setting of the ideal value of the stirring time and the setting value of the stirring time is the same as the setting of the "ideal value of the stirring speed and the setting value of the stirring speed".

[0135] The above units are only examples, and those skilled in the art may set different units according to actual needs when implementing this solution.

[0136] This embodiment solves the problem of low rigor of traditional production systems. The precipitant calculation module can accurately calculate the required precipitant input amount according to production requirements, thereby ensuring the accuracy and efficiency of the precipitation process.

[0137] The contents disclosed above are only preferred feasible embodiments of the present invention and do not limit the scope of protection of the present invention. Therefore, all equivalent technical changes made using the contents of the present invention description and drawings are included in the scope of protection of the present invention. In addition, the elements therein can be updated as technology develops.
