The concentration of gold in the electrolyte. The concentration of gold in the electrolyte determines the number of gold cyanide ions that diffuse to the cathode surface, resulting in a low concentration of gold, slowing down the deposition rate of…

Recently, many customers at home and abroad have requested technical articles on refining spent three-way catalysts to recover platinum, palladium, and rhodium. In order to provide a wide range of answers, I have written this article. From the perspective of…

Extraction method of silver from lead-zinc ore Silver plays a key role in lead-zinc ore as a co-occurring element. Smelting converts 95% of silver into crude lead, while refining converts 99% of lead into lead anode mud. There…

The extraction and refining of silver is mostly carried out in cyanide medium and sodium thiosulfate medium. There are not many studies on the extraction of silver in hydrochloric acid and nitric acid medium. 1. In hydrochloric acid medium, silver…

Loaded catalysts for platinum and palladium recovery Various types of supported catalysts enjoy wide use in the chemical and petrochemical industries. For example, they enable hydrogen peroxide production via the anthraquinone method, synthesize urea,…

Electroplating a platinum group metal surface layer on other metal substrates instead of the overall metal parts of platinum group metals can greatly save the amount of use. Among them, Pt plating, Pd plating and Rh plating are more widely…

From the perspective of environmental protection, directness, labor saving, and recovery rate, we recommend the use of smelting enrichment-hydrochloric acid iron removal-extraction separation-classic refining process. After nearly six years of experimental research and production implementation, this process has become a…

1. Alkali fusion separation: Mix the material evenly with a certain proportion of sodium hydroxide and sodium peroxide, and calcine at 800°C for 8-12 hours. After cooling, take it out and break it into pieces. Use water to leach the…

Plating platinum group metal surface layer on other metal substrates instead of platinum group metal overall metal parts, can greatly save the amount, of which Pt plating, Pd plating and Rh plating are more applications. Platinum plating is mostly used…
