[0069] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0070] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0071] Figure 1 A flow chart of a copper slag refining comprehensive treatment method of the present invention is shown.

[0072] like Figure 1 As shown, the present invention discloses a copper slag refining comprehensive treatment method, comprising:

[0073] S101, detecting the copper liquid based on a preset spectral device to obtain a total content value P0 of impurity elements in the copper liquid;

[0074] S102, determining whether the total content of impurity elements in the copper liquid is greater than or equal to a preset content threshold, and if so, sending the total content of impurity elements in the copper liquid to a preset analysis and control system to obtain a first feeding plan;

[0075] S103, based on the first feeding scheme, adding auxiliary materials into the copper liquid in sequence, and controlling the temperature of the copper liquid to obtain the copper liquid after the first treatment;

[0076] S104, detecting the copper liquid after the first treatment based on a preset spectral device to obtain a total content value P1 of impurity elements in the copper liquid after the first treatment;

[0077] S105: If the total content value P1 of the impurity elements is greater than or equal to the preset content threshold, continue to reduce the total content value of impurities in the copper liquid through the feeding scheme until the total content value P1 of the impurity elements reaches n Less than the preset content threshold;

[0078] S106, when the total content of impurity elements is P n When the content is less than the preset threshold, the slag is removed from the treated copper liquid.

[0079] According to an embodiment of the present invention, the content value of impurity elements in the first detection result of the spectrum on the copper liquid is set to P0, and the copper liquid is subjected to a spectral test each time after the impurity elements are removed by feeding. For example, after the first feeding scheme, the total content value of impurity elements in the copper liquid corresponding to the spectral test of the copper liquid is set to P1, and the total content value of impurity elements in the copper liquid corresponding to the spectral test of the copper liquid after the nth feeding scheme is set to P n , when the total content of impurity elements is P nAfter the content is less than the preset threshold, the impurity elements in the copper liquid are removed according to the preset slag temperature and slagging time, and the slag is removed by adding acidic and alkaline slag removal agents, and the slag is removed in two steps, namely acidic slag removal and alkaline slag removal.

[0080] According to an embodiment of the present invention, the step of sending the total content value of impurity elements in the copper liquid to a preset analysis and control system to obtain a first feeding scheme specifically includes:

[0081] Get the total weight of the copper liquid;

[0082] According to the impurity elements in the copper liquid, the auxiliary materials for removing the impurity elements in the copper liquid are searched in the preset impurity removal auxiliary materials table to obtain the auxiliary materials for removing the impurity elements in the copper liquid;

[0083] Determine the replacement coefficient of the auxiliary material for removing the corresponding impurity element in the copper liquid according to the preset chemical reaction formula of the impurity element in the copper liquid and the auxiliary material for removing the impurity element in the copper liquid;

[0084] The weight value of the corresponding auxiliary material is obtained by multiplying the content value of the impurity element in the copper liquid by the replacement coefficient of the auxiliary material for removing the corresponding impurity element in the copper liquid by the total weight value of the copper liquid;

[0085] Arrange the impurity elements in the copper solution in order of decreasing reducibility, and determine the order of adding the corresponding auxiliary materials;

[0086] The first feeding plan includes the weight value of the auxiliary material and the feeding order of the corresponding auxiliary material.

[0087] It should be noted that the first feeding scheme also includes the temperature range of the copper solution when the auxiliary material is added, the reaction time of the auxiliary material, etc. Different auxiliary materials and impurity elements will produce different chemical reactions. Therefore, the substitution coefficients between different auxiliary materials and impurity elements are also different. For example, in the chemical reaction formula of copper and silver sulfate, one copper atom can replace two silver ions.

[0088] According to an embodiment of the present invention, the step of obtaining an auxiliary material for removing impurity elements in the copper liquid specifically includes:

[0089] According to the impurity elements in the copper liquid, the preset impurity removal auxiliary material table is queried to obtain an initial auxiliary material set for removing the impurity elements in the copper liquid;

[0090] Extract the characteristics of the initial auxiliary materials and the corresponding characteristic values ​​in the initial auxiliary material set;

[0091] According to the characteristics of the initial auxiliary materials, the preset initial auxiliary material characteristic weight coefficient table is searched to obtain the corresponding initial auxiliary material characteristic weight coefficient;

[0092] Multiply the characteristic value by the corresponding initial auxiliary material characteristic weight coefficient to obtain the corresponding initial auxiliary material characteristic index;

[0093] Accumulating the characteristic indexes of all initial excipients to obtain the total characteristic index of the corresponding initial excipients;

[0094] Arrange the characteristic total indexes of the initial auxiliary materials in descending order to obtain the initial auxiliary material with the maximum characteristic total index;

[0095] The initial auxiliary material with the maximum characteristic total index is set as the auxiliary material for removing the impurity element.

[0096] It should be noted that the preset impurity removal auxiliary material table stores various impurity elements in the copper liquid and the initial auxiliary materials corresponding to the impurity elements, and all the initial auxiliary materials corresponding to the impurity elements form an initial auxiliary material set; each initial auxiliary material has different characteristics, including price, reaction time, stability, etc., and by comprehensively considering different characteristics, an initial auxiliary material is selected from the initial auxiliary material set as an auxiliary material for removing the impurity element.

[0097] According to an embodiment of the present invention, after obtaining the auxiliary material for removing impurity elements in the copper liquid, the method further includes:

[0098] Based on the preset chemical reaction, it is determined whether the impurity element in the copper liquid and the corresponding auxiliary material generate the first new impurity element. If so, the corresponding auxiliary material is set as a substandard auxiliary material; if not, the corresponding auxiliary material is set as qualified;

[0099] If the first new impurity element and other auxiliary materials do not react, the corresponding auxiliary material is set as unqualified;

[0100] If the first new impurity element reacts with other auxiliary materials and generates a second new impurity element, the corresponding auxiliary material is set as unqualified;

[0101] If the first new impurity element reacts with other auxiliary materials and no new impurity elements are generated, the corresponding secondary auxiliary material is set as qualified.

[0102] It should be noted that after selecting the auxiliary materials, it is also necessary to determine whether the corresponding auxiliary materials and impurity elements produce new impurity elements. If the new impurity elements can be removed by other auxiliary materials, the corresponding auxiliary materials are also qualified. If the new impurity elements cannot be removed by other auxiliary materials, it means that the corresponding auxiliary materials have done useless work, so it is necessary to replace the auxiliary materials that remove the impurity elements.

[0103] According to an embodiment of the present invention, after setting the corresponding inferior auxiliary material as unqualified, the method further includes:

[0104] Extract the initial auxiliary material of the second largest characteristic total index, and set the initial auxiliary material of the second largest characteristic total index as the auxiliary material for removing the impurity element; if the auxiliary material for removing the impurity element is still unqualified, extract the initial auxiliary material of the third largest characteristic total index, and set the initial auxiliary material of the third largest characteristic total index as the auxiliary material for removing the impurity element, and so on, until the auxiliary material for removing the impurity element is qualified.

[0105] It should be noted that the selection of auxiliary materials is in descending order according to the total characteristic index of the initial auxiliary materials. When the initial auxiliary material corresponding to the largest total characteristic index is unqualified, it is replaced by the initial auxiliary material corresponding to the second largest total characteristic index. If the initial auxiliary material corresponding to the second largest total characteristic index is also unqualified, it is replaced by the initial auxiliary material corresponding to the third largest total characteristic index, and so on, until qualified auxiliary materials are found.

[0106] According to an embodiment of the present invention, after obtaining the weight value of the corresponding auxiliary material, the method further includes:

[0107] Add up the weight values ​​of all auxiliary materials to obtain the total weight value of the auxiliary materials;

[0108] Divide the weight of any one of the auxiliary materials by the total weight to obtain the proportion of the corresponding auxiliary material;

[0109] If the proportion of the auxiliary material is less than the preset first proportion threshold, the corresponding auxiliary material is marked and deleted to obtain the deleted auxiliary material;

[0110] The deleted auxiliary materials are sent to the preset spare auxiliary material library for storage.

[0111] It should be noted that when the proportion of auxiliary materials is less than the preset first proportion threshold, it means that the proportion of impurity elements removed by the auxiliary materials is also relatively low. Therefore, it can be considered not to remove them first; giving priority to removing impurity elements with a large proportion can improve the efficiency of slag removal.

[0112] According to an embodiment of the present invention, the step of controlling the temperature value of the copper liquid specifically includes:

[0113] Obtain the temperature range suitable for using auxiliary materials and the temperature range suitable for slag removal;

[0114] Based on the preset temperature sensor, the temperature value of the copper liquid is obtained; based on the preset prompt operation interface, the current operation information is obtained; based on the current operation information, the current adaptation temperature value range is determined;

[0115] Determine whether the temperature value of the copper liquid is within the current adaptive temperature value range. If so, the current temperature value of the copper liquid is normal; if not, the current temperature value of the copper liquid is abnormal, and generate temperature adjustment information;

[0116] The temperature value of the copper liquid is adjusted based on the temperature adjustment information.

[0117] It should be noted that, according to the characteristics of the auxiliary materials, the adaptation value range of the corresponding auxiliary materials is determined, and the current operation information is displayed in real time in the preset prompt operation interface, such as auxiliary material addition operation, slag removal operation, etc., and the current adaptation temperature value range is determined according to the auxiliary materials currently added, wherein if the current temperature value of the copper liquid is lower than the current adaptation temperature value range, the heating function is triggered; if the current temperature value of the copper liquid is higher than the current adaptation temperature value range, the heat dissipation function is triggered.

[0118] According to an embodiment of the present invention, it also includes:

[0119] Before adding the auxiliary materials to the copper liquid, the auxiliary materials are screened through a grid of preset specifications to obtain a weight value that fails the screening;

[0120] Divide the weight value that fails to pass the screening by the weight value of the corresponding auxiliary materials to obtain the percentage value that fails to pass the screening;

[0121] If the percentage value that fails the screening is greater than or equal to the preset second percentage threshold, the corresponding auxiliary material information is generated;

[0122] Based on the added corresponding auxiliary material information, re-add the weight value corresponding to the proportion value of the auxiliary material that failed the screening.

[0123] It should be noted that before adding the auxiliary material to the copper liquid, the auxiliary material particles are screened to reduce large-particle auxiliary materials to increase the reaction rate of the auxiliary materials and impurity elements, thereby saving time. When the proportion value of the auxiliary materials that fail to pass the screening is less than the preset second proportion threshold, it means that the auxiliary materials that fail to pass the screening are relatively small, so there is no need to re-add the auxiliary materials.

[0124] Figure 2 A block diagram of a copper slag refining comprehensive processing system of the present invention is shown.

[0125] like Figure 2 As shown, the second aspect of the present invention provides a copper slag refining and comprehensive treatment system 2, comprising a memory 21 and a processor 22, wherein the memory stores a copper slag refining and comprehensive treatment method program, and when the copper slag refining and comprehensive treatment method program is executed by the processor, the following steps are implemented:
