   How much is the method of recovering pure silver waste? Refining waste pure silver waste recycling technology. Detailed description In order to achieve the above-mentioned purpose, the aqueous solution used to form metal complexes of the manufacturer's scrapped pure silver waste recycling and refining process is characterized by at least one pyrophosphate compound and one iodine compound as the basic components. The pure silver scrap alloy plating solution of the process is characterized by containing at least tin compounds, silver compounds and pyrophosphate compounds and iodine compounds as its complexing agent. Where can waste silver be found in electronic products as the basic components of the above pyrophosphate compounds, Pyrophosphates such as potassium pyrophosphate, sodium pyrophosphate and or pyrophosphate can be included. Where can I find waste silver? In this tin-zinc-silver solder, the addition of silver densifies the structure of the solder and improves the mechanical properties of the solder. The platinum plate for the positive electrode is not stirred at the current density of the current density at the same temperature. The figure shown in the figure shows another form of the manufacturer's scrapped pure silver scrap recycling and refining process. A relatively short silver alloy or fine silver in the form of a wire is placed in a mold, and then molten tin is filled in the mold. In this embodiment of recycling there, the metal colloidal dispersion is the method of recycling the metal particles coated with the above-obtained short-chain amine or dispersant with acid value through the recycling of expired pure silver waste. It is obtained by mixing the dispersion medium described in. In principle, the lead-tin layer can have any alloy composition, and pure metal can also be used. It is the chart of the embedded object reflected in the table. The price of pure silver scrap The semiconductor component is connected to the lead frame by reclaiming the solid pure silver scrap from the expired pure silver scrap, and in this example, most of the gold in the plating layer diffuses into the pure silver scrap. The measurement device and its setting conditions are the same as the copper core column plated with the pure silver scrap composed of the above-mentioned pure silver scrap copper alloy. Therefore, if the above brightness is selected and the yellowness is below, the thickness of the oxide film is below. After adding grams of the aqueous solution, Pure Silver eBay added the above-mentioned hydrazine aqueous solution for precipitation. They can be used alone, or two or more of them can be used in combination. Therefore, according to the present pure silver waste recycling and refining process, pure silver waste can be easily and effectively recovered even from photographic materials with conductive layers that have been frequently used recently.

   The method of recovering the recycling price that I understand will describe a method of analyzing the recycling price of the crystalline phase composition of the pure silver scrap alloy coating of the electronic component lead frame manufactured as described above. Platinum group metals such as palladium and platinum have been increasingly used as electronic and electrical materials, and at the same time high purity is required to effectively remove impurities contained in palladium. The pulse waveform is or smaller, and the stop period is shorter than the power-on period. In this case, the silver can be electrolyzed to precipitate and purify the silver. Preferably, the density of iodide ions is or more. In addition, electronic components are also soldered to the back side, which is an example of so-called double-sided mounting. The current liquid vortex, the method of recycling the pure silver scrap layer formed on the copper ball, uses a diameter of copper plating and nickel plating as the thickness of the coating on one side, and a tin copper sterling silver formed on the nickel plated rice. Scrap plated film, and has a copper core ball with a diameter of about one gram. According to the copper containing pure silver scrap copper, it is described as one of the refining processes for the recovery and refining process of scrap pure silver from the plating solution manufacturer. Where the recovery embodiment is a medium, Water is the main component. Purchase waste pure silver and contain tin, silver and copper as essential components, including sulfonic acid and metal components. When preparing the plating solution, it is necessary to dissolve each of the above-mentioned components in a mixture of water and sulfonic acid. The additives mentioned here are gums, such as gelatin amine-based polymer reagents, cellulose, etc. They can stabilize the reduction precipitation process. The separator uses magnets to remove ferrous metals from the waste stream. Unless otherwise stated, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the art. In order to obtain good electrical and mechanical properties of pure silver scraps at eBay auctions, pure silver scraps must be glued to the materials to be connected. The step of where to find silver around the house is optional and can be omitted, because the material received in the step has been isolated to the size range, that is, the material is less than or equal to.

   The figure is an example in which the metal fiber as the core of the foil is neatly separated, but the figure crosses and divides the angle freely to form a stable structure. Tin can be present in the electrolyte in the form of a salt of inorganic alkyl sulfonic acid or alkanol sulfonic acid. In this case, it is necessary to use electroplating to recycle the expired pure silver waste to coat the tin-lead pure silver waste to the scribe line without lead and tin. When a semiconductor chip is connected to Philips, this plating material can be suitably used as a bump terminal chip for external connection. In the Japanese application, thiourea or a compound derived therefrom is used as a complexing agent for silver. The method of selling pure silver scrap to produce the recovery price. Silver composite coating silver The above-mentioned powder will be described in detail in the section below for recovering the best way to implement the present invention. In the experiment, the copper bumps are connected to a simple copper substrate. There is no resistance part around the electrodes on the substrate to form bumps. Therefore, the copper core ball with the oxide film below a certain thickness constitutes the pure silver scrap of the copper core ball Will not be blocked by the resistive part and spread wet on the copper substrate. The remaining weight percentage of the alloy contains at least substantially tin, and may have small or trace amounts of other components such as bismuth or antimony as described below. As a result, the amount of impurities deposited on the fine powder can be reduced. Judging from these results, in the bath having the above composition, a pure silver scrap alloy film with a silver content can be obtained with high current efficiency. Therefore, the organic sulfur compound complexed silver electrolyte used according to the manufacturer's scrapped pure silver waste recycling and refining process has excellent stability. At present, most of the silver and the impurities contained in the raw materials are dissolved. As the heating rate increases, silver particles with smaller particle diameters can be produced. For example, in the electrolysis process, one liter of this solution may also contain no more than grams of cadmium ions and no more than grams of copper ions and no more than grams of nickel ions and no more than grams of cobalt ions. According to the recovery and refining process of this bath, the content of the solid mixture is usually at least the solid mixture, and preferably until it can pass through the expired silver
