Information on sulfuric acid, information on nitric acid digestion and recovery of rhodium, introduction of platinum carbon dust recovery method, very thin film, it is difficult to chlorinate only by flowing gas. Therefore, only in the initial stage of chlorination, methanol is included in the gas for reduction. In this way, the initially colorless and transparent molten salt turns dark red immediately after the gas flows in, and its color increases with the progress of chlorination after it is formed. It is therefore difficult to observe the state in the molten salt, but the end of the reaction can be known from the stoichiometric ratio of the gas flowing with the sample and the exotherm of the chlorine absorbent provided there. For the gas outlet, for example, a eutectic salt of about 10,000 is added to the eutectic salt, and a chlorination experiment is performed at the following gas flow rate for minutes. This is the amount of gas approximately times the stoichiometric ratio. The 2020 platinum and rhodium wire recycling price is now. In the early stage, there was almost no residue in the exhaust gas, but from about minutes, the remaining unreacted gas increased. This is because due to the reduction of powder, the chance of selling rhodium to the UK in contact with the gas is reduced. The remaining amount can be determined by the heat generated in the chlorine suction tube. The reaction rate of the final powder in the chlorination reaction in minutes is approximately.


 
   In this case, the rhodium buyer near me had a very high powder loading, and the volume of salt increased significantly due to the formation. The mass is approximately doubled when converted to, so the above conditions are somewhat extreme, in fact lower concentrations seem to be better. In order to see its capabilities here, it was done at high concentrations. In the final stage of chlorination, all unreacted substances proceed to the next step. After the sale of rhodium sponge chlorination is completed, stop the gas as described above, reverse the direction of the gas flow, drop the selling price of rhodium into the storage tank, seal it after solidification, and store the salt contained in the quartz tube. Then the reduction inserts the contained salt into a cleaned and sealed quartz reaction tube with a freshly attached container, heats and melts the salt, and at the same time makes the gas flow out of the bottom of the filter, and then inserts the quartz reaction tube from the top. The gas containing methanol flows through the quartz tube. The gas flowing from the bottom initially contains methanol, but in this case, precipitation occurs when the molten salt comes into contact with the gas on the metal surface. The filter filter is clogged. Even if it flows, changes must be made. Even if methanol-containing gas is circulated, it is difficult to confirm the precipitation due to the dark color of the molten salt. Currently, platinum rhodium 30 platinum rhodium 6 is recovered at a price. But when the concentration is close to the end of the reaction, the color of the molten salt becomes quickly disappear and becomes transparent again when it approaches zero. After confirming the end of the reduction reaction by selling rhodium near me, the direction of the gas flow was reversed again, and the molten salt was dropped into the storage tank. Rinse the ruthenium powder remaining on the top of the filter with water and scrape it mechanically.


 
   Since the obtained powder is often agglomerated and agglomerated, a mortar or the like is used for pulverization. The particle size of the obtained powder is from several to several tens, and the purity is from about 100 to about 100. The maximum is the specification sufficient to meet the requirements. The figure shows a photomicrograph of the metal structure of the product obtained by chlorinating and reducing alloy target scrap. The figure shows the overall configuration of a reactor suitable for chlorination and subsequent reduction reactions in molten salt when processing spent sputtering targets containing or alloys recovered according to the present palladium, platinum and rhodium. Now the price of organic silicon rhodium is recovered. Carry out a lathe test for cutting of discarded sputtering targets containing or alloys. Cemented carbide tools are too hard to be used after cutting tens of grams. The hardness is a small amount of facets obtained by this cutting. The figure shows a photo of the metal structure of a pure target plate that has been ground on a lathe. The figure shows a photograph of the metal structure of the alloy target plate ground with the end face of a lathe. Use end face samples for chlorination treatment. When chlorinated in salt, it is chlorinated by approx. approx. and the resulting chloride is reduced with approx. approx. approx. raw material ratio. The pulverization test was carried out on waste sputtering target plates containing or alloys. Using a ton press owned by Northeastern University, the alloy treated sputtering target was crushed by three-point bending. You can also fold more. The figure shows a photograph of the crushing test of the alloy target. Figure is a partial enlarged view of the figure. Even with a chisel, small debris can be crushed. Think it can be done by using a crusher
