Refining iridium powder is a complex process that involves multiple steps of chemical and metallurgical techniques. Here are the basic steps for refining iridium powder: Ore Processing: Iridium is usually found in platinum and nickel ores. In the initial refining…
Efficient Silver Recovery： In today's digital age, traditional film usage has declined, yet the silver in waste film remains valuable. This article explores an efficient method to recover this silver using centrifugal electrodeposition equipment. Principles of Centrifugal Electrodeposition Centrifugal electrodeposition…
Platinum refining involves a series of steps to obtain high-purity platinum. Here's a concise overview: Leaching: Platinum and other metals are dissolved in a solution with strong oxidants like aqua regia and NaClO3. Silver forms a precipitate while platinum dissolves.…
Wang water is an exceptionally potent oxidizer, capable of dissolving metallic gold. This ability stems from its composition, which includes concentrated nitric acid and concentrated hydrochloric acid. These components furnish ample oxidizing potential and chloride ions, facilitating the oxidation of…
What is the behavior of impurities during the silver electrolytic refining process? Answer: During the silver electrolysis process, based on the differences in properties and behaviors of each element, the impurity behaviors are classified as follows: 1. Metals that are…
A catalytic converter is a key component of a vehicle's exhaust gas treatment system, used to reduce harmful emissions. Catalytic converters typically contain three precious metal catalysts, rhodium (Rh), palladium (Pd) and platinum (Pt). Their content in catalytic converters depends…
