The *** of iridium catalyst is about 980 yuan per gram.
As a rare platinum group metal, iridium has a high market value due to its wide range of industrial and scientific applications, especially in the catalyst industry. Currently, the cost of iridium catalysts is influenced by a variety of factors, including the market for iridium, the amount of iridium in the catalyst, and the cost of the refining process. According to the latest market data, the *** of iridium catalyst is roughly around 980 yuan per gram. It should be noted that this ** is not fixed, but will fluctuate with changes in market supply and demand, raw material costs and other economic factors.
The best methods for spent catalysts usually include dry, wet, and wet-dry. The details are as follows:
1.Dry method: The waste catalyst is heated and melted together with the reducing agent and flux through the heating furnace, so that the metal components are reduced and melted into metals or alloys for **.
2.Wet method: chemical leaching is used to dissolve the valuable metals in the catalyst by acid or alkali solution, and then separated and purified by chemical precipitation, electrolysis and other means.
3.Combination of dry and wet method: Combining the advantages of dry and wet methods, a part of it is processed by the dry process first, and then further extracted and refined by the wet process.
4.Non-separation method and separation method: according to the specific composition and goal of the catalyst, select the appropriate technical route for processing.
In short, in practice, the choice of which method depends on the composition, content, type of carrier, value, rate, technical ability and cost of the catalyst.
