[0040] The fire assay analysis method is the main detection method for the analysis of gold and silver and trade arbitration in the gold industry at home and abroad. According to the provisions of the national standard, the main technological steps of the fire assay detection method include main steps such as batching, mixing, melting, cupellation, parting, and weighing. Among them, the purpose of the fire assay parting process is to convert the gold-silver alloy grains after cupellation into gold grains, which is convenient for the inspector to determine the mass of gold in the sample. At present, most laboratories have been using the working mode of manual operation one by one for fire assay parting operation. The operation has high repeatability, low detection efficiency, and is prone to sample loss due to operation errors. The detection results are greatly affected by factors such as the operator's technique, proficiency, or subjective emotions.
[0041] The process flow of fire assay parting is to first place the gold-silver alloy grains in acetic acid solution for heat treatment, then flatten the alloy grains and place them in a test tube. Dissolve silver with nitric acid of different concentrations, then pour out the gold grains for high-temperature annealing and shaping, and finally collect the gold grains for subsequent weighing. Its detailed operation steps include acetic acid treatment, flattening of alloy grains, treatment with 1+7 nitric acid, acid replacement, treatment with 1+2 nitric acid, cleaning, drying, annealing, collecting gold grains, etc.
[0042] As Figure 1 shown, in this embodiment, a parting device is also disclosed. The parting device includes a nitric acid dissolution device, a water washing device, a drying device, an annealing device, and a handling device. Among them, the gold-silver alloy is placed in the driving material carrying device, and the handling device drives the material carrying device to pass through the nitric acid dissolution device, the water washing device, and the heating device in turn.
[0043] The specific steps of the parting device for the gold-silver alloy include:
[0044] S1. Dissolving silver with nitric acid
[0045] Add appropriate amount of hot nitric acid (about 80-90 °C) to the material carrying device through the nitric acid dissolution device, make it react fully with the gold-silver alloy, and observe the reaction until the silver is completely dissolved. At this time, the solution is clear and only gold grains remain.
[0046] S2. Washing
[0047] Transfer the gold-silver alloy to the water washing device through the handling device, and repeatedly rinse the gold grains through the water washing device to fully remove the silver nitrate solution attached to the surface of the gold grains.
[0048] S3. Suction
[0049] Transfer the gold-silver alloy to the suction device through the handling device, and remove the excess water in the material carrying device through the suction device.
[0050] S4. Low-temperature drying
[0051] Control the temperature of the heating device at 150°C. After transporting the gold particles to the drying device by the handling device, dry the remaining distilled water on the surface of the gold particles.
[0052] S5. High-temperature annealing
[0053] Control the temperature of the heating device at 400°C. Transport the gold particles to the annealing device by the handling device. By heating the gold particles, anneal the sponge gold into harder golden-yellow gold particles.
[0054] As Figure 2 shown, Figure 2 As shown in the figure, it is a schematic structural diagram of a material carrying device provided by an embodiment of the present application. The material carrying device includes a tray 1 and a container 2. The surface of the tray 1 is provided with a receiving groove 3; the container 2 is placed in the receiving groove 3 and is used to carry the gold-silver alloy. During use, the handling device holds or clamps the tray 1 to transport the gold-silver alloy carried in the container 2 between various processes in the gold separation device.
[0055] Exemplarily, in this embodiment, the bottom of the container 2 passes through the tray 1 through the receiving groove 3. It can be understood that in this embodiment, the bottom end portion of the container 2 extends out of the tray 1. When it is necessary to heat the gold-silver alloy in the container 2, the handling device transports the container 2 to the heating device through the tray 1 and places the bottom of the container 2 in the heating device to increase the heating efficiency of the heating device for the gold-silver alloy in the container 2.
[0056] Exemplarily, as Figures 4 - 5 shown, in this embodiment, the cavity in the container 2 includes a flushing cavity 4 and a heating cavity 5. The heating cavity 5 is arranged at the bottom of the container 2, and the flushing cavity 4 is arranged at the top of the container 2. The heating cavity 5 is communicated with the flushing cavity 4, and the volume of the heating cavity 5 is smaller than the volume of the flushing cavity 4. It can be understood that in this embodiment, the gold-silver alloy is placed in the heating cavity 5. During the process of removing the silver nitrate solution attached to the surface of the gold-silver alloy and drying the remaining distilled water on the surface of the gold-silver alloy, distilled water is added to the inner wall of the container 2 by the water washing device, and then the excess distilled water in the inner cavity of the container 2 is removed by the suction device. During this process, in order to prevent the suction device from sucking the gold-silver alloy with a smaller volume in the inner cavity of the container 2 into the suction device, a part of the liquid is retained in the inner cavity by the suction device. And in this embodiment, the smaller-volume heating cavity 5 can reduce the amount of the remaining liquid in the inner cavity after the suction device extracts the liquid in the inner cavity, thereby increasing the drying efficiency of the gold-silver alloy in the container 2.
[0057] Further, as Figure 5As shown, in this embodiment, a protrusion 6 is provided at the bottom end of the container 2, and the heating chamber 5 is placed inside the protrusion 6. It can be understood that, compared with the main body of the container 2, the volume of the protrusion 6 is much smaller than that of the container 2. Therefore, when the heating device heats the gold-silver alloy, the unit contact area between the heating device and the protrusion 6 is larger than the unit contact area with the container 2, thereby further increasing the drying efficiency of the gold-silver alloy.
[0058] Furthermore, in this embodiment, the rinsing chamber 4 has a funnel-shaped structure. It can be understood that when the water washing device conveys distilled water into the rinsing chamber 4, the funnel-shaped rinsing chamber 4 can converge the distilled water to the bottom of the container 2, enabling the suction device to conveniently extract the liquid in the container 2.
[0059] Furthermore, as Figure 3 shown, in this embodiment, a plurality of receiving grooves 3 are provided on the tray 1. It can be understood that a plurality of receiving grooves 3 are provided on the tray 1, and a plurality of containers 2 are placed on the tray 1 through the plurality of receiving grooves 3, enabling the gold separation device to perform multi-component gold separation work simultaneously, further improving the working efficiency of the gold separation device.
[0060] Furthermore, in this embodiment, the plurality of receiving grooves 3 are distributed in a grid pattern on the tray 1. By arranging multiple groups of containers 2 regularly on the tray 1, it is convenient for each device in the gold separation device to process the alloy grains in the container 2.
[0061] Furthermore, in this embodiment, the container 2 is detachably connected to the tray 1. It can be understood that the container 2 and the tray 1 are designed as a split type. During use, the staff can detach the container 2 from the tray 1 separately, reducing the difficulty of use for the staff.
[0062] Exemplarily, as Figure 6 shown, in this embodiment, a buckle 7 is provided on the side wall of the container 2. The buckle 7 has an annular structure, and the receiving groove 3 is an annular stepped hole. The container 2 is snap-fitted into the receiving groove 3 through the buckle 7, thereby improving the stability of the container 2 when placed on the tray 1 for use.
[0063] Exemplarily, in this embodiment, a handle 8 is further provided at the bottom of the container 2. Through the handle 8, the staff can more easily take the container 2 from the tray 1.
[0064] Furthermore, in this embodiment, protrusions 9 are provided on both sides of the tray 1. Exemplarily, in this embodiment, protrusions 9 are provided on both sides of the tray 1. The protrusions 9 have an "L" - shaped structure. One end of the protrusion 9 is arranged at the edge of the tray 1 and is perpendicular to the upper surface direction of the tray 1. The other side of the protrusion 9 extends away from the tray 1. When the handling device transports the tray 1, it drives the container 2 to move by lifting the protrusions 9 on both sides of the tray 1.
[0065] Exemplarily, in this embodiment, a positioning hole 10 is further provided on the protruding edge 9. It can be understood that a positioning member adapted to the positioning hole 10 is provided on the manipulator assembly in the handling device. When the handling device handles the tray 1, the manipulator assembly is positioned through the positioning hole 10, which can not only assist the handling device in handling the tray 1, but also be clamped with the positioning member on the manipulator assembly through the positioning hole 10 to ensure the stability of the handling device during the process of handling the tray 1.
[0066] It should be noted that the present application is not limited to the above embodiments. The above embodiments are only examples, and embodiments having the same constitution and the same effect as the technical idea within the technical solution scope of the present application are all included in the technical scope of the present application. In addition, within the scope not departing from the gist of the present application, various modifications that can be conceived by those skilled in the art to the embodiments, and other ways constructed by combining some constituent elements in the embodiments are also included in the scope of the present application.
