Hereinafter, a sample preparation method and apparatus for analysis according to the present invention, that is, a sample preparation method and apparatus for analysis of recycled raw materials containing Cu, Au, Ag, Pt, and Pd used in copper smelting. Further details will be described with reference to the drawings.

  FIG. 1 is a flowchart showing an embodiment of a method for preparing an analytical sample according to the present invention, and FIGS. 2 and 3 show an analytical sample preparation apparatus for carrying out such a sample preparing method. The schematic structure of an Example is shown.

  According to the sample preparation method of the present invention, a coarsely pulverized mat for analysis containing Cu, Au, Ag, Pt, and Pd is used as a raw material. This coarsely pulverized mat is prepared by matting a sampled recycled raw material, then roughly pulverizing with a jaw crusher, reducing the analysis sample to 3 mm or less, finely pulverizing and bagging.

  First, an example of a sampling method and apparatus for collecting analytical sample raw materials from received recycled raw materials will be described. The method for obtaining the raw material for analysis used in the present invention is not limited to the following sampling method and apparatus, and can be obtained by various methods and apparatuses.

  As a result of many research experiments, the inventors of the present invention, for example, pulverize the recycled material in two stages even if it is a recycled material such as a printed circuit board that has not been pulverized, that is, primary pulverization. It is possible to obtain a recycled raw material of 30 mm or less that is effective for accurately grasping the content rate of valuable materials by coarsely pulverizing the material and then performing secondary pulverization to obtain a raw material of a predetermined size. I found out.

  In the present specification (and claims), the “size” of the crushed material means the size of the crushed material passing through a sieve having a predetermined mesh size. For example, the size of the crushed material of 30 mm means the size of the crushed material passing through a sieve having a mesh size of 30 × 30 mm.

  FIG. 5 is a flowchart showing an embodiment of a sampling method using a sampling facility.

  Referring to FIG. 5, according to the sampling method in the present embodiment, a recycle raw material that has not been crushed, such as a printed circuit board taken out of a used electronic device or the like, which has been carried in a pre-combination or the like, is hoisted. A primary crusher is charged by a crane and pulverized to a size of about 50 mm (ie, usually 10 to 100 mm) by the primary crusher (rough crushing) (step (A)).

  As the primary crusher, a twin-screw crusher is preferably used. As the biaxial crusher, for example, “Model KT42H (trade name)” manufactured by Kubota Corporation can be used.

  Next, the roughly crushed primary crushed material is pulverized to a size of 40 mm or less by a secondary crusher to obtain a secondary crushed material (step (B)). Crushed material larger than 40 mm can be returned to the secondary crusher and pulverized again.

  As the secondary crusher, a uniaxial crusher is preferably used. As the uniaxial crusher, for example, “Model MR7 / 32SVC Multirotor (trade name)” manufactured by Earth Technica Co., Ltd. can be used. This uniaxial crusher is provided with a screen (screen) having a mesh size of 40 × 40 mm, and a secondary crushed product having a size of 40 mm or less can be obtained.

  Furthermore, the secondary crushed material crushed by the secondary crusher is applied to a screen (sieve) having a mesh size of 30 × 30 mm (step (C)) to obtain a crushed material of 30 mm or less, preferably 20 mm in size. A sample is taken by a sampling device. The secondary crushed material larger than 30 mm is returned again to the secondary pulverizer and pulverized (step (D)). Thereby, a crushed material having a size of 30 mm or less can be efficiently collected as a sample.

  As the sieve, a vibrating sieve is preferably used. As the vibration sieve, for example, “Nominal model 3 * 8, single floor type, ML type (trade name)” manufactured by Earth Technica Co., Ltd. can be used.

  The secondary crushed material having a crushing size of 30 mm or less that has been sieved by the vibration sieve is fed to a sampling facility equipped with a sampling device similar to the sampling device 200 described above with reference to FIGS. Then, a sample (raw material) for analysis is collected (step (E)).

  In the above description, a printed circuit board is used as a recycling raw material, but the present invention is not limited to this, and it can be an electric part scrap such as a gold-silver candy or an IC chip, or a plating scrap.

  Next, referring to FIG. 1 to FIG. 3, a sample preparation method and apparatus for analysis according to the present invention, that is, a recycled material containing Cu, Au, Ag, Pt, and Pd, which is processed in a copper smelting process. A sample preparation method and apparatus for preparing a sample for analysis will be described.

  The analytical sample raw material used in the preparation method and apparatus of the present invention can be used after matting the analytical sample (raw material) described with reference to FIG.

  That is, the analytical sample (raw material) obtained by the sampling device is further melted and matted with a sulfide ore into a matted analytical sample raw material.

  According to this example, as shown in FIG. 1, the matted analytical sample raw material of the recycled raw material obtained as described above is further transferred to a pulverizer and has a size of 3 mm or less. Coarsely pulverized. The crusher is preferably a jaw crusher.

  The crushed material obtained by roughly pulverizing the matted analytical sample raw material with a pulverizer, that is, the coarse pulverized mat, is referred to as a tray-like storage container (hereinafter referred to as “tray”) of the analytical sample preparation apparatus 1. ) 4 (refer to FIG. 2) and stored in the sample magazine 3 (3a, 3b, 3c) (refer to FIG. 2 and FIG. 3).

(Analytical sample preparation equipment)
Here, with reference to FIG.2 and FIG.3, schematic structure of the sample preparation apparatus 1 for analysis using a robot by a present Example is demonstrated.

  According to the analytical sample preparation apparatus 1 of the present embodiment, the robot 2 is disposed in the center. As the robot 2, “IRB4400” (trade name) manufactured by ABB is preferably used.

  Around the robot 2, a sample magazine 3 (3a, 3b, 3c) for storing the tray 4 is arranged.

  In the present embodiment, three sample magazines 3 (3a, 3b, 3c) are provided, and each sample magazine 3 (3a, 3b, 3c) has a large number of trays in the present embodiment. There are 52 storage compartments, that is, storage chambers. Therefore, in the present embodiment, 156 trays can be stored by the three sample magazines 3 (3a, 3b, 3c).

  Further, around the robot 2, in order from the sample magazine 3 (3a, 3b, 3c) in the counterclockwise direction, a bagging device 5, a fine pulverizer 6, a splitter (reducing machine) 7, a sample weighing machine 8, and a waste product are disposed. A box 9 and the like are arranged. Furthermore, as shown in FIG. 3, a cup magazine 10 (10a, 10b), a cleaning device 20 and the like are installed as necessary. The cup magazine 10 stores cups 11 (11a, 11b) for storing and transferring matted samples, and the cleaning device 20 uses a cup for storing mats, which will be described later, after use. It is for washing.

  In particular, in this example, “TT-8C” (trade name) manufactured by Toyo Automatic Co., Ltd. was used as the bagging device 5. The bagging device 5 is provided with a barcode sticking device 40 for assigning a lot number or the like to the bagged sample.

  Further, the fine pulverizer 6 was a vibration mill and used a big mill (a mill in which a ring and a stone move and pulverize). 1.5 kg of pulverization was possible. As such a fine pulverizer 6, “HP-M1500” (trade name) manufactured by Harzok Co., Ltd. can be preferably used.

  Furthermore, the analysis sample preparation apparatus 1 will be described in detail.

It can also be configured. This is because bagging takes time, and if the first bagging is completed, the second sample cannot be taken out from the weighing machine 8 and the processing speed of the entire system is reduced. . For this reason, in order to maximize the operation rate of the apparatus, priorities of processing are set. For example, a system in which two cups 11b are temporarily placed in the cup magazine 10b and then packed in a bag can be obtained.

  The remaining sample remaining in the cup 11b after weighing by the weighing machine 8 is transferred to the disposal box 9 by the robot 2 and discarded.
