Continuous method of removing impurities from crude silver nitrate

摘要

Herein is disclosed a continuous process for manufacturing purified silver nitrate solutions comprising the steps of: a) transferring a crude silver nitrate solution, together with a slurry comprising silver oxide, to a multistage agitated reactor, thereby forming a mixture; b) maintaining a continuous weight percent undissolved solids inside the reactor with a differential densitometer such that silver oxide is 10 to 80 weight percent of the undissolved solids; c) transporting the first mixture through the reactor over a period of 15 minutes to 3 hours to form a reaction product; and d) filtering the reaction products through a continuous filter to form a silver nitrate filtrate. <IMAGE>
