How to extract silver from silver-tungsten alloy
To silver tungsten alloys in dilute nitric acid, energetic response due to the silver can dissolve in dilute nitric acid generated, but tungsten can't dissolve in dilute nitric acid, this filter can get rid of tungsten, then filtrate transpiration crystal crystal, eventually will be heated, crystal get silver may be powder (get) the final two steps should be done in an airtight container, because may contain no response from the filtrate of nitrate, nitric acid heating can differentiate into toxic gases, and the final step heating can also differentiate into, exhaust using alkali absorption.
