   Sponges sell ruthenium by adding magnesium oxide in the precipitation step to precipitate iron oxides such as hematite or spinel or hydrated iron oxide, and iron can be recovered from the leachate. The former are preferred because they are easier to achieve solid-liquid separation. The bismuth ruthenate recovery leaching mixture includes valuable metal-rich solution leaching, and the residue solid is in the form of a suspension. The leaching mixture can be fed to the solid-liquid separation step as known in the art. In order to separate the leachate from the solids, the solids can be processed to recover valuable metals therefrom and or disposed of as waste solids. Iron can be recovered alternatively by forming oxides by pyrolysis. A part of the bismuth ruthenate leaching solution can be removed by the stream, and then the sponge ruthenium precipitation step is carried out. For example, a stream of magnesium oxide can be combined with the stream to form a mixed hydroxide precipitate such as nickel and cobalt. Hydroxide to produce products and valuable metal-poor leachate. The remaining part of the leachate may contain nickel and cobalt, and these nickel and cobalt can be recovered separately to restore the pace. For example, a part of the sponge ruthenium leachate can be subjected to a solvent extraction step to obtain a cobalt-rich extract and a cobalt-reduced leachate.

   The extract of cobalt-rich ruthenium for sale can be processed to obtain cobalt-containing solutions and concentrates. Leachate depleted in metals. The cobalt-reduced leachate can be processed, sold as osmium, and the leachate stream depleted in valuable metals. Pure ruthenium gold coins can combine and process valuable metal-poor leachate to regenerate the leaching agent. In particular, ruthenium ingot and hydrochloric acid can be regenerated. In addition, magnesium oxide used in valuable metals can be recovered in steps. With reference to the figure, the discharge stream of the valuable metal-poor leachate can be processed in steps to remove impurities therefrom. The bismuth recovery can then process a portion of the purified valuable metal-poor leachate in a step, for example, by precipitation of bismuth ruthenate hydroxide or sulfide to obtain recycled metal chlorides such as magnesium chloride. A part of the metal-poor leachate of purified value can be subjected to a thermal hydrolysis step to obtain a magnesium oxide stream. The magnesium oxide reduction leachate produced by the hydrolysis step contains, the sponge sold ruthenium can be subjected to an additional evaporation step to obtain recycled waste gas from human-computer interaction pyrolysis, which can be used for pre-evaporation, not shown, to enrich the concentrated solution and reduce energy costs. But by adding gaseous hydrogen chloride to the solution, the degree of partial or pre-evaporation can be reduced or even eliminated. Hydrogen chloride can be formed from chlorine. Sponge Ruthenium In this way, bismuth ruthenate can reduce or eliminate the energy required to evaporate water.

   In the alternative embodiment shown in the figure, the leachate is treated in two or three purification steps to recover the valuable metals precipitated from the solution by adding the magnesium oxide provided by the stream. After each bismuth ruthenate recovery and purification step, the treated percolate is subjected to a solid-liquid separation step to obtain a solid, and the bismuth ruthenate can be sent for disposal or further treatment to separate valuable metals from the reduced percolation of valuable metals. filtrate. The treated leachate is then treated. Sponge ruthenium recovery step to obtain valuable metal reduction leachate, which can be recycled through a thermal hydrolysis step; and mixed nickel cobalt hydroxide product, and then sell ruthenium, which can be further processed to separate valuable metals . Or the bismuth ruthenate can be processed sequentially to the leachate to produce a nickel-containing product and a cobalt-containing product. It should be understood that sponge ruthenium can sequentially increase the amount of leaching solution by sequentially adding additional amounts of magnesium oxide to precipitate a specific ruthenium investment or a group of metals. It should also be understood that sponge ruthenium can adjust the leachate in various ways, including the sale of ruthenium coins with different regulators such as alkali. The advantage of using magnesium oxide is that the required amount of magnesium oxide can be produced by this method, and the addition of magnesium oxide does not add any additional ions in the leachate, which may require the use of additional processing steps. Controlling the leaching agent, especially the redox potential, sells ruthenium to convert the sulfide in the sponge ruthenium to the sulfide ore material in the leaching step into hydrogen sulfide instead of sulfate ions.
