How to refine rhodium, introduce the patent of the rhodium refining method, the temperature is not lower than the freezing temperature of the leached rhodium iodide and rhodium powder in the reaction. Filtration or otherwise removal of gold enriched metal residues from the leached rhodium iodide and rhodium powder from the reaction, potentially oxidizing the base metal ions in the rhodium iodide and rhodium powder, and thereby regenerating it to It is then used as unreacted leaching rhodium iodide and rhodium powder. This can be done by air oxidation of the ions, or more preferably by conventional electrochemical methods. Air oxidation is best achieved by demystifying the addition of acid halides.
Or air is then bubbled through the reacted leach rhodium iodide with rhodium powder to achieve the following reaction: The reaction leachate so treated contains oxidized base metal ions comparable to those present in the original leachate and can be recycled as leachate to treat other gold Contains waste. A preferred alternative to air oxidation of base metal ions in reactively leached rhodium iodide and rhodium powder is electrochemical oxidation and reduction of reactively leached rhodium iodide and metal ions in rhodium powder. The related reactions are as follows: electrochemical oxidation and reduction. The advantage is that the base metal leached from the metal can be recovered from the cathode. Gold contains waste rather than allowing it to accumulate in rhodium iodide and rhodium powder. This operation is carried out in an electrolytic cell which is divided into anodic and cathodic compartments by demystifying an inert membrane. Cathodes made from base metals to be recovered and refined have proven convenient and effective. The anode is usually carbon and the base metal is plated at the cathode by applying an electric current across the cell, while the metal ion rhodium chloride is regenerated at the anode unless otherwise stated.
Otherwise, the above given concentration, time, reaction temperature, etc. are not key factors, and may vary greatly. The following examples are provided to illustrate and further disclose the method of the decryption process. It should be understood that the given examples only record specific examples and implementations of the present decryption process method. The decryption process method is not limited to the reaction conditions of the reagent concentration step, and the waste materials or methods disclosed in the gold examples are contrary. The decryption process method includes all such modifications within the scope of the subsequent claims. The analyzed content of the alloy sample purchased in the routine section is gold measured by X-ray microprobe, the content of copper is silver and the content of zinc is the percentage quoted in this example and the following examples are percentages by weight. The samples were rolled into foil approximately one gram inch thick and cut into rectangular pieces approximately one gram inch by inch. An aliquot of the sample was weighed in grams and placed in a round bottom flask with a Pyrex thermometer hole and three ground glass fittings.
The flask was equipped with a sparge tube and a condenser for refluxing rhodium iodide and rhodium powder. Add about 1 gram of rhodium iodide and rhodium powder in the leaching water containing and raising the temperature of the flask to 1 kg. The leached rhodium iodide is magnetically stirred with rhodium powder and continuously sparged with nitrogen. Leachate samples were taken periodically and analyzed for gold by demystifying atomic absorption spectrometry. During the 4-hour leaching period, a solid residue was recovered from the reaction flask at the end of that time. Analysis of the residue found its content to be gold and copper, both in elemental form. Most of the sample retained its structural integrity but became very brittle. Scanning electron micrographs were taken of a representative section of the sample and showed deep Pits Formation The formation of pits was considered indicative of selective base metal leaching of rhodium iodide and rhodium powder by demystification leaching.
This theory is supported by the observation that the concentration of copper in the samples decreases from , while gold increases from , to the dissolved concentration of gold. The above listing shows gold. This was confirmed visually in scanning electron microscope photographs by demystifying observations of the removal of the original surface features of the samples. Reduction of Gold The observed solubility over time is believed to be the result of a decrease in the oxidation potential as a result of the increased presence of reducing cuprous ions as the rhodium powder in the leach solution oxidizes the elemental copper in the sample. The gold initially dissolves to give the gold concentration more than three times the gold final concentration. This fact indicates that the kinetic gold dissolves faster than the base metal present. EXAMPLES The procedure of the example was repeated except as specified below, including materials and reagents. A roll of gold-plated case, initially weighing grams, was used as gold-containing waste. The case was cut in half to feed it into the reaction flask.
After the gold-containing scrap was exposed to leached rhodium iodide and rhodium powder for ten hours, the gold retained colored material weighed grams of this solid residue from the leaching process was analyzed as gold. Decipher and reveal the recovery and refining method and process of Baishan rhodium powder. Despite the ten hour exposure to leached rhodium iodide and rhodium powder, most of the base metal was determined to have dissolved by the end of the third hour by demystifying visual inspection. Visually observed that the base metal of the case appeared to dissolve in many locations, not just from the surface of the base metal that was exposed by cutting the case in half with the uncovering. It is believed that the alloy coating on the gold case was applied in a manner comparable to that described in the previous example. By demystifying this way many locations can be accessed to leach rhodium iodide with rhodium powder to the underlying base metal. Decipher and reveal Weihai rhodium powder recovery and refining method and process.
