Waste catalyst treatment methods: 1. Recycling: Some spent catalysts also have recoverable value. For example, the precious metals in spent catalysts can be recycled and used to prepare catalysts again. 2. Incineration treatment: Burn the waste catalyst directly and control…

Silver nitrate is a commonly used chemical reagent, often used in the preparation of other silver compounds, as well as as analytical reagents, photographic developers, etc. However, impurities in silver nitrate may affect its application effect, so it is very…

low-grade iron oreLow-grade iron ore is a resource-rich but low-grade ore, and its effective separation is crucial to improving the utilization value of the ore. This article mainly introduces the beneficiation methods and processes of low-grade iron ore, including physical…

A method for extracting lead and silver from zinc oxide leaching residue by wet process. The method includes: using NaCl-CaCl2 solution as the leaching agent, leaching the zinc oxide leaching residue with chloride salt to achieve the separation of silver,…

Gold extraction from circuit boards It is understood that in addition to the 30 per cent of inert oxides and 30 per cent of plastics contained in the circuit boards, there are also 40 per cent of…

As a representative enterprise in the field of gold, silver, platinum, palladium and rhodium refining equipment in China, Jinquan's marketing budget in this area is "0". Where does the budget go? Research and development, full! The…

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…
